I don’t understand why these videos get a dislike. This is all fantastic stuff.

I think it would have added to the chemistry aspect of lithium in discussing Castle Bravo that it was due to miscalculations of the percentages of the lithium isotopes that were expected to participate in the reaction that caused the miscalculation of the yield.

This professor is the best chemistry teacher I have ever had! Thanks for the channel!

Please! Keep remaking your element videos. The old one was disappointing, but even as a huge chemistry buff I learned a lot from this video. Can't wait for more!

Hi Brady, I am absolutely in love with this channel, and I thank you all for making this happen for so long. I was wondering if you would be interested in hearing a video suggestion(s). I really find the chemistry that is a part of the pharmaceutical and healthcare industries to be very interesting, and I was wondering if you could make more videos that pertain to those fields. For example, maybe you could do a video on the chemistry of current cancer treatments. I know you have done videos on medicines and drugs before, like aspirin, but I hope you can make more of these kinds of videos in the future. Keep up the great work, and have a fantastic day!

'Fun' facts which they left out: The Castle Bravo nuke was 1000 times stronger than each of the Hiroshima and Nagasaki nukes. And at the time of the detonation, an estimated 20,000 inhabitants of the area got radiation poisoning which caused an untold amount of birth defects throughout the following years. And the surviving victims received a measly $5,550 each in 1954 (about $48,900 in 2016).

I worked in a chem lab serving the mining industry for 13 years. Towards the end of the time the accountants decided that broken glassware could only be replaced every three months. Thus if you needed 17 flasks, crucibles or beakers to run duplicates and a blank on 8 samples and you didn't have 17, you had to find some way to work around it. Consequently most things took longer to do. The lab closed within three years of this, partly due to strangulation by bean counters.

It looked to me that the Li had burned out. I'm not nit picking but why not fill the beaker first with LN2 and then light and lower.. I'm also thinking of the oxidation product in a N2 atmosphere. Lithium Nitride?

How do lithium batteries work and why are they better? I would love to see a sequel. Great video as always Sir Martyn and Brady.

Soooo, when will you make a video about alkali metals and coulomb explosions? I think this theory is quite well accepted by now. And even if it isn't, it definitely deserves a video where you explain it. :)

I am a new subscriber and wanted to say how much I appreciate all of these wonderful videos made by the University of Nottingham.

Lithium is my alltime favorite element. Ever since I was a kid I've loved nukes and at the age of 6 I already knew most of the tests by heart like BravoB etc. Though for the first time I have to add one use that the Professor didn't mention; Lithium can also be used in submarines where it can purify the air and re-release oxygen from being bound with other elements and compounds. This is why subs theoretically can stay submerged for so long.

Lol I think the professor has the same bomb fascination as myself. I didn't learn anything here, but in all of the other videos I learn something.

You completely glossed over why the bikini atoll bomb was much more powerful than expected. The lithium duteride was composed of 60% lithium 7, which was calculated to be inert. Needless to say, it was not, and turned what was supposed to be a 4 megaton detonation into a 15 megaton one.

What of the metallic hydrogen experiment that was compressed to a metal state.

I'd like to see something about the effect of wood charcoal (oak in particular) on distilled alcoholic beverages, as far as actually putting small amounts into bottles of, say, scotch or bourbon. It really seems to make a difference.

I wasn't expecting all that content. Very scarry!!!

I always get a confused sense of awe, inspiration, and fear when I see the videos of the Atomic/Hydrogen bomb tests.

Does anyone know the name of the old video of the guy explaining the deuterium atoms that was used in the video?
