The prof is absolutely amazing at explaining things. He is what makes these videos not just fun but actually interesting and understandable.

These guys make fantastic and educational videos. their series on Au was outstanding.

Fact: Lighter boats go faster. Fact: Sodium is light. Fact: We should make boats out of sodium! =D

it's not so much a matter of weight but more so a matter of displacement. the more water an object displaces, the more buoyant it is. this is why ships are able to stay afloat despite weighing thousands of tons. so in fact, a ship sinking isn't the ship getting heavier, it's the ship displacing less water. sure weigh can affect the buoyancy as well but you don't want to so much as make lighter material as much as make a bigger vessel.

It is about time that somebody did a slow motion video.

I've been so fascinated by these slow motion videos! I hope y'all find more things to video in slow motion❣ I've learned so much from all of you. Thank you. 😊

These slow motion videos are great. Its one thing to make a video where your audience learns something, but in these videos it seems Dr. Poliakoff and the other people with PHDs are learning a fair bit as well.

High speed video of anything that happens quickly is cool... getting the explanation is what makes this freaking cool.

Love seeing these slo-mo experiments, not just for the slomo, but also for the interesting explanations of the reactions and why they happen as they do. Can't wait for the others.

Turn on HD, hit fullscreen and enjoy! Thank you guys for these great videos.

Yes, the explanation of what's really happening there add a great deal of value to these videos. Can't wait for the next ones!

Can't wait for even more videos~ It's always so exciting to see experiments being explained and SLOWED down XD

I absolutely love 4:10 where the visible vapours are reverborating up and down, oscillating to balance the pressure in the flask with the pressure in the fume hood.

These reactions in slow motion were very good idea, I love them! Can't wait for more!

not only was this video pretty informative, it was relaxing.

In a way its very beautiful, kind of elegant when slowed down, but it all happens so fast that you can't enjoy it with the naked eye. Can't wait to see some of the other reactions.

I want to know what would happen if you mixed every element known to man at precisely the same time in one container.

I'm not too sure about these predictions of violent reactions.... after all a lot of these lelements won't react with each other. The elements that are reactive will probably be scrabbling over the same partners. Only so much oxygen or whatever to go round meaning the violence of the reactions might not be as energetic as expected.

Because if you added them in equal amounts and had enough of each to see it, all the trans-uranic radioactive nightmares would near-instantly produce radiation and heat sufficient to blow you apart if you were anywhere near it. Let's say you had a gram of each. The astatine alone would give off about a megawatt of radiation constantly, and it's not even the most radioactive thing we know of (by a long shot). The heat from that alone would cause a grenade-like explosion. When you have all the 26 trans-uranic elements in there too, there's no other possibility. You could get an incredible (though probably not nuclear) blast as a result, along with some intense radioactive contamination of everything around. One gram of every element known all at once would produce a fantastically deadly dirty bomb.

Being able to see things in slow motion adds a whole new dimension to understanding things that happen at high speeds. Another amazing set of videos are the shuttle high speed launch videos (2 vids). You get to see things that just aren't visible to the naked eye. The engine nozzles vibrating is my favorite, along with the oscillating of the SRBs as they pass the cam at something like 7hz? They explain it all in the vid too. Slow motion is amazing. Can't wait to see the following vids! :)

Extremely enjoy these videos !

I was worried that these slow motion videos would just be pretty images without any added value. However, the professor's breakdown of what is actually happening in the reaction is very very intersting. Fantastic video.

Destin + Periodic Videos = Awesome. That's just science.

This is really quite truly impressive. I thank you guys, because this is exactly the sort of thing we need to get more people interested in chemistry.

Awesome! Can't wait for the others!

He has got a good point...he made it more exciting than I thought it would be...I was like 'its just sodium reacting with water, all we are gonna get is a small explosion' but its his way of analysis that makes this video worth watching...

When I was a kid, we lived across the street from a cylindrical water tower that was partially cut down, resembling an amphitheater. My older brother 'liberated' a one pound chunk of sodium from his H.S. chemistry lab, & dropped it into a pail of water centered in this amphitheater (then ran). It took so long to react that it went off at midnight. It sounded like a large bomb, & made a flash that lit up the city like daylight. We then watched thousands of lights go on all over the city!

Beautiful shot of that in the beginning of the video !

I'm not a scientist, so I really appreciate these videos. The amount of details is right for the target audience (even a little too much I think if you consider the average youtube viewer). I Think this is a fantastic way of bringing science closer to average people like me, and I'd be happy to know that some of my tax money is spent this way (which it isn't as I'm not from the UK).

Smarter Every Day + Periodic Videos has to be one of the greatest collaborations ever... This may be better than peanut butter and chocolate in a Reese's

This slow motion series is so great.

These videos are great. I wish they would of had videos like the ones you guys are sharing when I was taking chemistry. Thanks

I really Love this videos, and great explanations from the professor.

Woop Woop Can't wait to see the other videos!

This is beyond awesome. I love the video but I love it even more after it is explained to me. Thank you for making this (and the others)!

Nice one, can't wait for the rest!

really love your videos! keep up the good work!

pumped for next week!

I love this. I can not wait until next week.

Hi Brady! These videos are just pure awesome. Keep up the good work:)

Thanks! Wonderful job task you have done :)

Science... why you so awesome?! This is easily one of my favorite channels on KZread. Thank you for doing this. :)

Thank you for another interesting video

I love it when my favourite youtube channels collaborate :)

This is a great channel.

So pumped to see Cesium go up

I love this channel.

Thanks Braddy!!!

Fantastic video. I love the slowmotion video's

Hahahhaaaaa! You, professor, amaze me everytime I click on your videos. You, explain this wonders so clearly, you Beakman's british father!

Lovely vid you guys have wayy to much fun

Wow. Intense and awesome reaction!!! I have no idea why we make such complicated Experiments in school to see a exothermic reaction when u just need a small piece of sodium and a drop of water.

wow! amazing how different such a well known experiment can be when altered slightly

Definitely one of my favorite sodium videos!

I'm REALLY looking forward to the Cs.

AMAZING SCIENCE VIDEO!!! You can really see what's going on when you slow things down! Of course there just has to be one genius to dislike the video

Watching how energetic the contribution is, it makes me wonder what the feasibility of a sodium/water engine would be.

awesome series!!!!!11

Another great video (clicked liked before even watching :p). Also looking forward to the upcoming videos. High speed footage is a great addition!

thank you, this is fantastic! cant wait for the next one:)

I learned lots, thanks!

Imagine a plate of sodium with a thin layer of oil on its surface. If that plate was left outside in the rain, would each successive water droplet break through the surface of the oil? If it did, would it create a collage of mini-reactions? or would the water want to pool and cause less, but larger reactions? I dont have the means or knowledge to do this myself, but i think this reaction would look pretty awesome.

That was a very educational video and i hope to watch more :-)

what matters the most is that is made a very awesome video ! :) Excited for more :D

Congratulations from Brasil, please keep making this excelent videos to contemplate the internet with more helpful videos, not more of stupid videos...A hug to all producers!

That's one of the the reasons why I take so long editing videos - checking I haven't made a mistake like that.

Wow, I can't wait to see the other alkali in slow motion! Awesome video with a huge drool factor!!

Wow I loved the end of the second try. It's pretty cool that Na can become molten metal in this reaction.

Thank you very much for these videos! Excellent to show to my 10 year old girl to get her interested in the wonders of chemistry.

And now I wait with great anticipation.

In gen chem we talked about this reaction today. My professor said that because of the reaction was so vigorous, which is why it doesn't sink. Now i got research to do, thanks. And its not much less dense than H2O other than by 3.0 x 10^-2. Great info, must show my professor.

We did this in my high school physics class many years ago. Someone managed to cut off a sizable chunk for the bar of sodium and dropped it into a toilet in a nearby bathroom. As I recall, it blew the toilet to pieces. That was the end of our sodium experiments. Crazy stuff!

This reminds me high school day's when the teacher put a small sodium piece into water and followed it w/ burning match. Nice speedboat turned out to be. Didn't have this kind of explosive end though. Extra footage later of the slo-mos would be nice to have .. but later.

Thank you for this video, it was a nice suprise when I woke up.

Love this reaction. Thanks

Amazing!

The professor is correct with respect to why the reaction forms something of a geyser in the beginning frames of the explosion. The effect is similar to that of a shape charge seen in explosive munitions. Something for SixtySymbols to investigate. ;-)

excellent chemistry !

That's right! Destin is working together with periodicvideos to make this slow motion videos.

This is really interesting!

I remember playing with this in school. My chemistry teacher was by no means a safety fanatic either, and we'd often get big splatters of molten sodium on our uniforms

I so can't wait. Seriously, generating the big boom with that little amount of sodium seriously peaked the cool meter.

This is the kind of thing that is more awesome (and probably more educative) with a higher framerate... Still, this is awesome as it stands :)

This discussion was on on point with the slow mo.

I'm excited to see the other alkali metals!!!!

Thanks!

More slow motion videos please!!! :D

brady, at around 4:09 you can clearly see the smoke\vapor doing a wave like motion back and forward. i understand its a physics issue, but can you make a short explanation to what that is? awesome videos, btw!

Have been waiting for this one, excellent! I suggest magnesium v fire (slow motion) if possible :)

(the ions kind of alternate back and forth in the solid form of NaCl, sharing their charge with each other in the form of Na+ and Cl- to maintain stability in a crystal lattice*) is what i meant to say at the start there

Great video, I can't wait to see Cesium.

I'm very excited to see the rest. Obviously, Francium wouldn't be tested, but why not Lithium? I love it as much as Debbie loves Boron.

Dear Brady, Can you make a video about the importance of Chemistry in the medical field? Thanks

A few weeks ago, on the Ri channel, I saw a video of a reaction between caesium and flourine which was pretty intense but also didn't last very long. I was wondering if there's going to be a slow motion video on that or, if not, if you could make one.

Make a bag of sodium shavings, throw it in boiling water, and what will be left of your carbonized body will have my respect (he lied).

So awesome

This this and more of this. I've stopped watching a lot of channels because they got their hands on a slow mo camera, and that's all the channel turned into. Slow mo is great, just when it has commentary to go with it.

I heard the mention of thermocouples. Ever considered doing a video on the Seebeck effect?

This stuff is amazing :)
