Roberto Firmino has been worth his weight in gold to Liverpool since arriving in a £29 million move from Hoffenheim back in June 2015
Brendan Rodgers signed a lot of duds during his tenure at Anfield, but the Brazilian forward certainly wasn't one of them
Firmino has been one of the most important players for Liverpool since Jurgen Klopp replaced Rodgers in October 2015
Without him, the team simply doesn't function nearly as well. Unlike most strikers, Firmino isn't obsessed with scoring goals
He's a real team player who works tirelessly when he's on the pitch. Former Liverpool striker Dirk Kuyt called Firmino the 'complete player' in April and it was hard to disagree with his assessment
"He's a great goalscorer but he's also a team player in everything he does. I don't know him quite well, but if I see him playing he just wants to win with the team and he's not the type of player who wants to score for himself," Kuyt was quoted as saying by Goal
"That, for me, is the biggest thing about Firmino. "He's scoring great goals but he's also giving great assists and then you are, in my eyes, a complete player, a great thing for Liverpool
"I think he's also a very hard worker, he's selfless. I watch almost all the games and I see then he's always giving his all
Sometimes he's not scoring goals or giving assists, but he is always giving his all
" Firmino executes a no-look nutmeg v Cardiff During his time at Liverpool, Firmino has scored a few audacious no-look goals
But against Cardiff City, he managed to execute an incredible no-look nutmeg. Seriously
Chased to the byline by Víctor Camarasa, Firmino has no choice but to improvise
And didn't he just. Watch the video here… Here it is in slow motion. Now that's what you call cheeky
What a player. Liverpool fans on social media all went crazy after the clip was posted online
Here are some of the best tweets… No doubt kids up and down the country will be trying to execute the no-look nutmeg now

10 Signs You're Being Too Hard On Yourself - Duration: 4:39.
10 signs you're being too hard on yourself you probably don't realize that
you are putting too much pressure on yourself this happens frequently because
our world demands perfection that forces its people to push their limits
unfortunately this practice is not always good considering the fact that
people have different capacity in dealing with problems if you think you
have these behaviors you should consider stopping or slowing down a little bit in
this video I'm going to share with you some behaviors that reveal you're
putting too much pressure on yourself but before that please subscribe click
the bell and watch this video until the end to know the complete information 10
behaviors that reveal you're putting too much pressure on yourself number one you
are tired of trying after multiple trials you probably stopped trying or
struggling you feel so desperate because things are failing apart quickly and
there's nothing you can do anymore if this happens to you there's a chance
that you've put your best effort and pressure to yourself that you don't see
opportunities anymore number two you start looking back again
most people are really great in recalling history past experience and
bitter events this sets them back since they make people think unnecessary
things indeed past events can be the lesson however once is enough and being
stuck there is not an option of relaxed people number three you think you are
bad people who are not forced will not feel good at all in fact they feel
burdened and they don't feel like life is fair when this happens desperations
follow and you eventually force yourself too hard to achieve something that is
impossible to be achieved number four you don't love yourself when
you think you are bad you start blaming yourself you start hating yourself for
not being capable or unskilled you also curse yourself to death because it seems
like everything is fighting against you when this happens
you actually put too much constraint in yourself and you will not gain anything
in the end number five your life is full of negativity if you feel like you are
going into a creative ways or when you feel like your life doesn't go anywhere
enjoyable and it just come to you there is probably something wrong one thing to
blame is that you work too hard that you don't enjoy the process anymore if this
happens you will only think the negative not the positives like usual number six
you always feel depressed what is the more obvious sign compared to feeling
and looking depressed it is very easy to pick up the desperation from others and
if others tell you so there's a problem with you there's a high chance that you
feel so because of forcing yourself to expectation that you cannot meet number
seven overthinking another great sign that you may experience when attacked by
extreme pressure is overthinking now you become extremely skeptical and you
overthink everything it's like you are afraid of making mistakes and
unfortunately it makes you perform less than desired number eight unrealistic
expectation yes expectation is the greatest turtles that
you possibly cannot face it is unfortunate but it is important for
people to keep everything realistic number nine you are not easily satisfied
you always want more and more you always want to be better than your currently
are you always want something greater for you though it is really good to have
expectation you should be grateful and satisfied sometime otherwise you are in
the loop of endless satisfaction pursuit number ten you don't take a break it is
always suggested that you stop for a while to enjoy what you've earned or
create it take some time a week or so to reflect and enjoy otherwise you are
forcing yourself to take what you cannot take well those are the ten behaviors
that reveal you're putting too much pressure on yourself so really cool

REMEMBER WHEN... Rough Seas ► All 4 Adventure TV - Duration: 1:13.
How good is it going out in the big boat?
All time.
Look, it's good when it's clear, and we've got the clear blue skies and the calm waters.
But it's not always like that.
This is going to be a bone-jarring 3 hours ahead of us.
The 5-metre groundswell predicted isn't a problem, as the distance between the waves is huge.
The chop on top is what is giving us the grief.
On the way out, the crew pass overhead.
And as you can see, it's a lonely old ocean out there.
How messed up was that trip?
Mate, the ocean was just a mess. It was puss.
Jackin' up.
Now Simon has a novel seat in rough water on the motor.
He reckons it's the smoothest spot on the boat.
Personally, I think he just enjoys it.
It's a bit rough.
Ten years of All 4 Adventure. I can't believe it.
Mate, that is a Decade of Dirt.

Ash PUMPS Misty's BUTT?! (Secrets Revealed!) - Duration: 25:18.
hello how are you guys doing today my name is black Tarzan and today I'm super
excited to bring you this brand new video of ash pumping Misty's but I know
what you guys are thinking Wow does Ashley really pump Misty's but it
like can you show this on YouTube yeah I can and if you guys want to see it you
all you have to do is just follow the four steps that I'm about to tell you
and you will be able to see this amazing clip because you know YouTube lets me
program the YouTube algorithm lets me program all my videos to not show you
certain video footage unless you do what I say it's a feature only available to
those people who have like really high amounts of subscribers you know I have
like 87 thousand subscribers so obviously it lets me do it
so yeah so to be able to see ash pumping Misty's but all you have to do is number
one you have to be subscribed with notifications turned on number two you
have to like or dislike this video number three you have to just leave me a
comment and then number four you have to share the video I'm gonna be listing all
the instructions down below in the description if you guys can't hear me
very well or I'll leave it in the I'll also leave
a comment just in case you know you guys get really lost so yeah go ahead do all
those steps subscribe the notification is turned on be sure to like this video
leave a comment and share this video and you will be able to see Ash and Misty
having some smoky time so definitely be sure to do that anyway let's get right
into the video let's go
okay so before I show you guys the clip of Ash and Misty you know of ash pump
and Misty's but let's first talk about misty because we have to understand the
important story that goes behind this now misty first appeared in like the
first or second episode of Pokemon you know we saw her she was like ash Ash's
Pikachu was hurt and Ash had some problems and he needed some help so you
know misty had a bike and ash was like don't miss can I get you a bike and
misty was like no but ash was it you know he's a straight-up thug he doesn't
care about nothing so he just went in a few collab Misty's
bike he just sped away with it I mean this is like it's crazy I mean like
people in the hood do this all the time but ash is about a straight-up you know
just go to light a poor innocent girl who can't even defend herself and
literally still it was bike I mean a lot of people just thought oh it's a cartoon
but you know I should have been more you know responsible he maybe should have
asked for permission or rented it you can't just go up to someone and just
like legit just like taking steal their bike like that's kind of messed up but
yeah you know ash he just you know I'm saying he just went up and he took her
by anyway so after that he speeds into the the forest and you guys know what
happens I mean you can watch the second episode of Pokemon I'm not gonna go over
most of you are younger though I mean I'll tell you there's this term called
Gen one or like I'm a gen Warner it's like you you y'all kids need to go out
there and you'll need a watch the first season a Pokemon if you haven't because
it's really good I think it's I mean I like the new ones too
get me wrong that the old ones also have a special thing to it I think a lot of
people take the old Pokemon episodes for granted but those were hyped to guys
like not gonna lie anyway so we don't see misty for a long time and then you
know later up in a couple of episodes ash nice Missy again and she's like yo
can I have my bike back ash is like yo I'm sorry your bike got trashed like I
don't know what to tell you mr. like your buddy got crashed I you know burned
it and I don't have the money to pay you back and so misty was like alright then
you know you don't have the money to pay me back I'm gonna have to follow you and
be your companion and go everywhere with you and don't second-guess these guys
you know it's it's October over here so it's kneading season
I'm not sick and just just needed I mean I'm just blowing my nose all right
anyway so it's kind of weird she's like well if you don't have the money for my
bike I'll just follow you around and we can just do stuff together and you know
a lot of slow curious because they're like two young people and they're
traveling around the world together so I mean one has to wonder what goes on
after hours you don't like what happens and so that's why I made this video to
show you because the creators of Pokemon just released this new footage of Ash
and Misty just going at it so remember guys if you want to see this clip you
got a number one subscribe and because I'm about to show it right now so the
final warning is number one you need to be subscribed to the black Tarzan
channel but the notifications turned on number two you need to either like or
dislike this video number three you need to leave a comment and before you need
to
what do you need to do
number four you need to share this video
now some of you guys on the last video we're having some technical difficulties
and I am going to tell you that if it doesn't work with the first account now
some of you are mobile some of you are on a laptop or a desktop or a tablet or
whatever Kindle or Kindle Fire or whatever anyway what's going on is if
you're on mobile because most people use mobile and it doesn't work for you
create a new account or use like your mom your sister your brother whatever is
account sign in subscribe and do all the steps and then refit but like close and
open the video and restart the app or a browser or whatever and it should work
for your computer you know restart your browser try with a different account and
it should work there's no reason it shouldn't work a lot of people who are
just saying that in the comments are really literally just trolling there's a
lot of trolls on my channel but it will work for you so just keep subscribing
make new accounts or whatever and yet you should be able to see it because I'm
not just gonna give it I'm not just gonna show you this content free because
you know I worked hard to find this I had to contact a lot of like Pokemon
officials and secret you know Pokemon agents so I'm not just gonna release it
to you guys for like nothing I mean that doesn't make no sense so go ahead and
I'll people probably provide a technical support in the comments so let me know
anyway
yeah anyway you know I think Ash and Misty are going to have a very
successful future together I mean I do end up seeing ash proposing
to misty and then getting getting married you know it's a possibility that
could happen so don't think I mean in my opinion some people say like he might be
with another female in Pokemon anime but I mean there's some good competition I
mean you got Serena which the story people people made Pokemon literally
change the whole story they put her back in his childhood
just to like introduce Serena so Serena's like the huge competition and
right now 50/50 split I really don't know is it going to be missed you or is
there gonna be sore arena or is it gonna be may I I don't think it's gonna be me
it could be it could be there's some I've been poking some strings here I did
make a video about hash in May I made a video about all the pokemon female urges
but I did make a video about ash in May so it could happen guys leave me a
comment below like saying who you think ash is gonna end up with because it's
very hard to protect us in the future but Misty is like one of those special
characters because they brought her back I need ash and miss you were super
friends and they brought her back to the new Aloha series Pokemon anime so what
does that tell you I mean that tells you that misty was a huge and super
important character in the anime that they were gonna even bring her back as a
new special character they didn't even do that - Serena forget sir they didn't
really do it
yeah guys just I literally I just woke up I was like I'm gonna make this video
because a lot of people need to see this new leaked footage so that's why I kind
of wait for Bellefleur it's literally
it's like 9 a.m. I woke up like 2 hours ago
I'm starting to get better with my sleep patterns and I'm starting to take care
of myself and actually go to sleep on time so that's the best plus I really
don't know what else I should say on this video I mean I've gone through a
lot of other things yeah
testing
shit
all right so let's go over misty
misty is a character whose first appearance was in the very first episode
of the anime series in the first episode she first meets ash after fishing out of
the water when she was trying to get away from the Frank espero ashlynn takes
Misty's bike from her in order to escape the sparrow which is then wrecked by
pikachu thunder shirt misty then tracks down ash and all his adventures
until he can pay her back up although she eventually forgets about the body
and becomes one of Ash's closest friends in the process however at the end of
their journey through Johto region Misty's bike has been fully repaired as
she departs to return home to swimming suit to assume her duties at agenda
she's currently a Cerulean City junior after the older sisters
testy
Oh
misty has short hair orange hair tied into a side ponytail she has green eyes
and fair skin she wears a yellow tank top that shows her midriff red
suspenders blue denim shorts that stop her at her thighs and red sneakers with
yellow lining and white laces her whole midriff is showing but her bellybutton
is usually not grown on however it is visible when she is in her two-piece
swimsuit in Sun moon she later maintains her original outfit
in her return to Pokemon series Sun and Moon beneath her outfit is her strapless
two-piece swimsuit which is worn by her counterpart in both games pokémon red
and blue in SM 43 when Regents collide misty has a key stone hidden at the back
of her ponytail in one episode in pokémon chronicles her primaries hop is
replaced with a yellow sleeveless hoodie shirt but maintains her denim shorts
with her sneakers from her primary outfit and color of her denim shorts
were purple her new outfit at the advanced
generation series when she meets up with ash and Brock and Hoenn consists of
yellow sleeveless vest with a dark blue but the dark blue collar red swimsuit
yellow shorts and whorin shoes personality misty has a slight
inferiority complex mostly due to the three older sister Daisy the oldest
violet second from oldest and Lily third from
oldest who formed the group the three sensational sisters their synchronized
swimming group and refers to misty as the run or the weaker one
this complex the mitten diminishes over time as misty grows closer to them until
misty
resumes her duties at the cerulean sea gym leader her sisters were the ones who
directly ran the gym although Ashe although when ash came
along to get his cascade batch it was misty who battled him pour it explicitly
referring to herself as being one of the gym leaders during this instance misty
specializes mainly in water type Pokemon which are her favourite type but she's
had other types and she also deeply admires Laurel Laurel a as a ice type
pokemon trainer misty aims to become a world-class pokemon trainer and her well
trained pokemon reflects her aspirations of becoming so her least favorites have
a pokemon is the butt type pokemon a deep
as she is
now she has a deep-rooted fear of them except for the kind she sees as cute or
pretty however misty Misty's fear lessons over
the course of the series but is not to the point where she's totally gotten
over it as shown in a real cleffa anger as your series continues she gradually
shows herself to be kind and sensible sometimes she would restrain Brock from
girls off and pummel him away from that by the ear recommending him for his
behavior this trait continued with hit with the
friends who join ash on his journeys after she parted ways with him following
their journey through the johto reason misty is a great Fisher making good at
making lures for her fishing and an amazing battler due to being a gym
leader biography
misty can be very nice to her friends but will then quickly change moods in a
short amount of time particularly anger she is quite proficient in anything
having to do with water type with water as she can be seen in certain episodes
where she has the ability in fishing swimming an overall water type Pokemon
training even though she wanted to stay with ash misty felt obligated to watch
over the gym since her sisters would be gone on their world trip the two went
their separate ways and Misty resumed her duties as gym leader at Cerulean
City Gym advance generation series in this series misty wears a pale yellow
vest sleeveless jacket and a dark blue button and a collar of the same color
she wears yellow shorts a Princeton leotard under her vest and a burnt
orange high tops and white socks Missy only appeared as a guest star and
the remainder of the Pokemon series in one of her cameo appearances the indie
advanced generation series her togepi evolves into toget togetic mister
releases togetic after it chooses to stay behind to defend the mirage kingdom
and Togepi paradise
after ash finish finishes competing in the Hoenn league he returns home to
Pallet Town to find misty waiting for and however she isn't
the only one to rejoin ash May Max and Brock join him as well for the battle
frontier challenges she travels with the passion for two episodes and then
returns to her gym shortly afterwards misty returns alongside with Barak in
sm0 42 when ash returns to cancel after his travels in a low on for his school
project of his classmates she is one of the special guests along with Brock who
is one it is the one who pinched Brock's ear to meet up with him ash holding him
after the exploration she is the only one who releases a loli in Pokemon
compared to Kanto Pokemon and helping Lana to find her PO polio under the
depths of the lake she stays ELISA stars each a Brock's as crobat and Ash's like
an rock to rescue their friends Pokemon from Team Rocket the next day they
traveled to Cerulean City for extra curricular lessons and after Brock tells
ash about his younger brother Forrest who currently runs the patch where city
gym miss he tells them her sisters are travelling much to Brock's depression
in sm0 43 misty shows to them the inside of the newly rebuilt
Cerulean City Gym and became thankful for her Psyduck
to guard the gym she also uses this to battle against malos tini and Lena
Lana's papi Leo in a handicap but when Saida gets with a severe headache and to
unleashed confusion on both pokemon misty calms it despite it it hurts
its head misty later battles ash against using this website is so hard to read on
I apologize guys what does it say
she also reveals key stone hidden at the back of her hair clip of her ponytail as
she mega evolves her diary dos despite her strategy her mega guru dose
was defeated by Pikachu who uses the Z move the gigavolt hot - after giving
Lina Malo and Lily some Cascade badges she and Bronk will told by ash to visit
him at a low low which they agreed before ash and others depart misty
became interested in Ash's earring as she admits that she teases ash making
them laugh oh man that's cool Oh should we go through the trivia yeah
why not why not go clear trivia guys
by some trivia guys Missy is the first victim of a reoccurring gag in the enemy
where Ash's Pikachu destroys every main female characters bike this gag was also
transferred to Mei and Dawn however this gag did not affect iris
Bonnie or Serena because they did not have buns iris and Bonnie were shocked
directly by Pikachu while Serena wasn't shocked at all
all right that's pretty much it for today guys I really don't have any more
information about misty at this time I hope you guys enjoyed watching the video
thank you guys so much for watching my name is black Tarzan thank you guys so
much for watching I really appreciate it peace boots

Lab Notes: Terpin Hydrate failures, Urushibara Nickel failure, and Additional Sodium Work - Oct 28th - Duration: 12:35.
Greetings fellow nerds.
This week there is very little sodium work, as i'm waiting for more chemicals to arrive in the mail.
I also landed a new job.
So things have been hectic as i settle in so my videos are going to come out less often but once i have a good routine going i should be returning to normal video production.
Now in other channel news i have received another community guidelines strike on my channel.
This time against my synthesis of sodium cyanide video.
And to be honest, this is the first strike i actually accept.
Now i personally think the educational value outweighs the danger.
But i can see it from their point of view why they wouldn't like it and removing it isn't contradictory to the policies of youtube.
Nor is the reason excessively broad like when they took down my synthesis of the antimalarial drug pyrimethamine.
So i'm not going to fight this particular strike.
I suppose after indiscriminately taking down so many videos, they had to find a valid one eventually.
But since my channel is closer to being banned, i do hope i last long enough to produce my last great project, the sodium synthesis.
Now i as said before i'm still working hard on it and progress has been steady.
In particular i'm trying to get more catalysts for my sodium experiments.
Buying them through the mail is one option, but as i wait i wanted to try making some.
Now one catalyst candidate that's been suggested to me a lot is something called terpin hydrate.
It's based off of 4-terpineol and is actually the product of hydrating the double bond.
The original alcohol group undergoes a migration by passing through an alkene intermediate.
What we essentially get is two tertiary alcohols on one molecule.
Now i'm not sure if this would do us any good, and it might make the resulting alkoxide too polar to be soluble but we might as well give it a shot.
Now i looked for literature on how to make it and it seemed simple enough,
mix a source of terpinenes like tea tree oil or turpentine with dilute sulfuric acid and stir for a prolonged period.
So i did that, i mixed about 200mL of tea tree oil with 200mL of water and added 30g of sulfuric acid and then stirred.
The literature says this should yield a precipitate of terpin hydrate overnight.
Then i stirred for about three days and at the end of it, nothing happened.
I then left the mixture in the back of my fume hood for three weeks and finally a tiny clouding of stuff seems to be coming out.
It's not very much though.
I'm not even sure if we could recover that.
Now some literature sources suggest high concentrations of acid so i tried again with 50mL of tea tree oil, 20mL of water, and 50g of sulfuric acid.
Looks like we're getting some reaction.
But even after a few days I wasn't seeing anything solid.
At this point i kinda abandoned this line of inquiry.
Not because it can't work, i'm sure i'm probably doing something wrong.
But i think my efforts are best spent on more promising avenues like finding an off-the-shelf catalyst.
I may yet revisit terpin hydrate as a catalyst if everything else doesn't pan out.
I'm still leaving this flask in the back of the fume hood in the hopes the reaction continues.
Anyway, as found in a previous lab notes video.
4-terpineol from tea tree oil was found to be a workable catalyst, but decomposes with time so a large starting amount is necessary.
4-terpineol also needs to be isolated from tea tree oil by fractional distillation, which is not all that easy at the temperatures required.
Now a way to solve both problems is to hydrogenate tea tree oil.
This is already well-known chemistry.
Basically add hydrogen to the double bond and hopefully make the resulting alcohol resistant to decomposition.
This would also make all olefinic impurities aliphatic which should be as inert as the mineral oil we're using to run our reactions.
Unfortunately this does not happen by itself.
If you feed hydrogen into an alkene, nothing happens.
So we need a catalyst.
The most common catalyst in the laboratory is palladium on carbon.
If you want actually see palladium on carbon being used for hydrogenation then i recommend checking out Applied Science and NileRed,
both of those channels perform hydrogenation of vegetable oil to make margarine.
They're excellent videos and i've linked them in the video description.
Now palladium on carbon is within the abilities of the amateur to make but like making tertiary alcohols,
it's a rather involved process and you also need to buy palladium.
The effectiveness makes it cheap since you can use very little, but the initial cost might be prohibitive.
So to make my hydrogenations more amateur friendly, i decided to try and make another catalyst called urushibara nickel.
It's not as effective as palladium, but the required chemicals aren't too hard to get.
First i had to make nickel chloride.
Nickel chloride can be purchased online but nickel metal itself is often easier to get.
You can even hack it out of nickel metal hydride batteries and it will work.
So to convert nickel metal to nickel chloride i added it to hydrochloric acid.
But nickel reacts very slowly at room temperature so to speed it up it needs to be boiled.
Eventually this forms nickel chloride.
I made a lot of it since i wanted to do other experiments with nickel and I don't have nickel chloride as a stock reagent.
I then boiled it dry and eventually obtained nickel chloride.
Now making urushibara nickel precursor isn't that hard.
Zinc powder is obtained and a one tenth mass equivalent of nickel metal is weighed out in the form of a nickel salt.
Like our nickel chloride from earlier.
We then add water to both and heat them up until they boil.
From what i read in the literature the more vigorous the reaction the better the resulting catalyst, and thus why we're boiling everything.
Now looking back at this point i think i screwed up.
If you look over at the zinc it seems be rather pasty.
I don't think that's zinc, i think it's more zinc oxide.
The zinc powder i was using must have oxidized over the years over to zinc oxide.
What i should have done before i started was wash the zinc with dilute sulfuric acid.
Zinc oxide easily dissolves in sulfuric acid but zinc metal actually dissolves very slowly because it has high hydrogen overpotential.
Unfortunately i didn't think of that in time, so i went on to the next step.
Mixing the boiling nickel chloride solution directly into the boiling zinc paste.
Now this extremely vigorous reaction is actually perfectly normal.
We're getting a very exothermic metal displacement reaction with the nickel depositing very fine particles onto the zinc.
It's so exothermic that it's boiling the mixture further.
So my crappy zinc still has enough good zinc in it to make this reaction work.
Although i still think i would have been better off using good zinc.
Anyway looking back i should also have used a bigger flask to contain the reaction.
Luckily I had the foresight to install a splash arrestor on the flask before i started to deal with exactly this sort of occurrence.
As you can see i definitely got my money's worth here.
Anyway, I let the reaction continue until it stops.
Next we filter our mixture to get our precursor.
Be sure it wash it with lots of water and finally with some methanol to get rid of all the leftover salts.
And here it is after drying.
Yeah i really think i have way too much zinc oxide.
Hopefully i get some activity out of this but if i don't, i know what to fix.
Anyway, this is the Urushibara nickel precursor.
Basically it's ultrafine nickel deposited on zinc particles.
In this form it's stable indefinitely but not directly useable.
To make it useable for hydrogenation it's reacted with a strong base or weak acid to destroy the remaining zinc and release the nickel particles.
Then those particles are filtered and used for hydrogenation.
But that's best done just before you actually do perform your hydrogenation.
The activated nickel loses activity as it's exposed to air, so it's best kept in this precursor state when you're not using it.
Anyway i'm still preparing for the hydrogenation so i'll get to that eventually.
But as you can see, overall, the process for making the catalyst doesn't seem to be that hard.
If this works as is i'll make a proper video with masses and variables, and if not i'll try again.
Now i've been running a concurrent sodium experiment where i ran with an excess stoichiometric ratio of sodium hydroxide to magnesium.
If you recall i already ran this test awhile back to see if we could avoid using dioxane by making sodium without magnesium contamination.
We found that it was very difficult to finish since the reaction just kept getting slower and slower and even after three days it never finished.
While i decided to revisit that experiment since i had more time now and this time I used huge amounts of sodium hydroxide, almost twice as much and i ran for several days.
Finally the reaction flipped over and all the magnesium was consumed but something interesting happened, the sodium broke up into a very fine dispersion.
You can see it here almost like sand.
Let me see if I can get closer and get a macro shot, and there we go.
It's clearly a spherical metal so it's not the original magnesium just worn down.
When i poured it out most of the slurry passed through the sieve and whatever did collect was very little.
So it seems like a little bit of magnesium is needed to keep the sodium metal together in large globules.
I actually noticed this effect very early in my experimentation but i wasn't certain it was due to excess sodium hydroxide as i was also dealing with glassware destruction at the time.
So I had to consider the possibility it was a glassware contamination problem.
But now it looks like it really is an effect of using excess sodium and letting the magnesium be consumed.
Now you might be wondering how does magnesium prevent the sodium from breaking up.
What i think is happening is the magnesium is imparting a negative charge to the sodium as the magnesium is oxidized by the reaction conditions.
This charge alters the surface tension of the sodium and either allows the sodium to easily coalesce with other droplets of sodium or makes it harder for the sodium to detach and break up.
Perhapes both effects are at work.
We've actually seen a very similar effect way back in the gallium beating heart experiments.
In those experiments the gallium metal changes its surface chemistry in a sulfuric acid solution whenever it's left on its own or when when it touches an iron wire.
In this case we have sodium metal for gallium metal, and magnesium metal for iron.
Bottom line, in order for us to get great sodium coalescence under these reaction conditions we need a small amount of magnesium to maintain the right surface charge on the sodium.
So it looks like we'll always need to run with excess magnesium.
First, because the reaction becomes terribly slow if we don't.
And second, and perhaps the more important reason, because the magnesium maintains sodium cohesion.
You might be thinking that we can use dioxane to recover the sodium droplets from this slurry.
While that might be possible it only underscores the continued need for dioxane.
If we're going to keep using dioxane then we might as well keep with our current methods of using dioxane to separate sodium from magnesium metal.
You know, looking back, i remember lots of amateurs running with excess sodium or potassium hydroxides
when they were doing their experiments since magnesium was the more expensive reagent.
Perhapes a lot of their reaction failures weren't failures at all, but simply loss of product because it was this fine dispersion.
They did report that the resulting slurry was exceptionally reactive, but couldn't collect any large pieces of sodium or potassium metal.
Now that we know product cohesion is dependent on excess magnesium this might offer an explanation.
So you amateurs that were working on this research years ago and kept failing but got highly reactive slurries.
Perhaps you did succeed and didn't know it.
So that's what i've been up to for now as i wait for more chemicals to arrive.
Hopefully they'll get here soon and i can start testing, but if not i'll get to work on hydrogenation of tea tree oil.
Thanks for watching.
At this point i'd like to thank my patreon supporters.
I would never have bothered to research anything this thoroughly or produce lab notes without your approval.
It's because of you that we have come this far, thanks

YOUNG AVENGERS ?? Top 5 Famous Superheroes Turned Out To Be LGBT - Duration: 6:51.
MovieDay OmLamis
The rise of discussion about LGBT in Indonesia made me wonder
Are there fictional characters like superheroes who also have LGBT?
The fact is, there is
Behind the figure of every super-strong hero who is famous
authoritative, handsome, beautiful and helpful
apparently some of them are LGBT people
The following is "5 superheroes who turned out to be LGBT"
Wiccan
Wiccan is a super hero and is a member of Young Avengers
a team of superheroes whose members are on average teenagers
Like the Avengers
Young Avengers also has the duty to protect and protect humans from enemy threats
Wiccan has the real name William "Billy" Kaplan
a mutant from an old man who is also a super hero
Scarlet Witch and Vision
At a glance Wiccan does look handsome and charming
but apparently this one super hero is actually a gay
He has a love relationship with Hulkling
which is his teammate at Young Avengers
If you want to know the romance of these two superheroes
You can browse by yourself, because I myself am not brave enough to see it
Hulkling
Hulkling is a super hero who is also a member of Young Avengers
Hulkling has a similar appearance and strength to the Hulk
but these two superheroes
has no family or love relationship at all
Hulkling is a shape shifter
has the ability to change shape and shape
Hulkling was born with the name Theodore "Teddy" Altman
his parents were aliens
As explained
Hulkling has a love relationship with Wiccan
is his teammate at Young Avengers
This means that Hulkling is gay
This super hero pair is known as
"The most famous gay couple in the Marvel world"
Batwoman
Batman itself first appeared in DC Comics in 1939
Following in the senior's footsteps, Robin appeared a year later
Many controversies arose at that time
many say that Batman and Robin are more than just superhero duos
and they are both gay couples
In 1956, Kate Kane was first introduced as Batwoman
as well as being a "love interest" for Batman
it aims to ward off the controversies
In 2006
Batwoman was reintroduced as a person of Jewish and lesbian descent
DC Comics editorial staff strives to diversify the world of DC comics
and also to be more connected to modern readers
Considering that lately there has been widespread exploitation of similar relationships such as lesbian and gay
Harley Quinn
Maybe many are confused why we put Harley Quinn on the list of superheroes
Harley Quinn itself is indeed a criminal
which is a "sidekick" of Batman's archenemy, Joker
But on several occasions
Harley Quinn has also helped Batman to capture the Joker
In some series like Suicide Squad
Harley and some other super villains instead become the main characters and heroes in the story
This series was taken to the big screen
Return to Harley Quinn
He is one of the most famous comic figures in the world DC
Harley Quinn was originally a psychiatrist at Arkham Asylum
The Joker at that time became his patient
It's not Harley that makes the Joker sane
He was even made crazy by the Joker
Harley Quinn is known to have complicated love relationships with the Joker
At first glance, the Joker only uses Harley and doesn't hesitate to kill him
but on the other hand the Joker sometimes acts like a friend and lover
Harley Quinn is also known to have a love affair with Poison Ivy
this makes him one of the bisexual characters in the comic
Mystique
Mystique's iconic appearance that has blue skin and yellow eyes
especially after the wide screen version by beautiful actress Jennifer Lawrence
make this super hero (or super villain) easy to recognize
The initial member of X-men has the shape shifter capability
make it can turn into anyone
Mystique is a transgender because of his abilities
He is a lesbian, together with his partner Destiny (Irene Adler)
Mystique even adopted a child who was also a mutant, Rogue
That was the five super pagans who turned out to be LGBT members as well
sorry if there is one that you like or your super hero

to get a video update about the next unique cool movie
