By popular demand, this is the full version of my reaction to NileRed’s Atomic Trampoline

"And so I immediately started blasting-"

Guessing the high beryllium content is why this specific type is rarely made now. a piece of that breaking would create its own biohazard.

I love how the recipes for all these metallic glasses read (to anyone without a background at least tangentially related to materials science) as just the most random recipes.  It literally feels like they just pick 4 or 5 elements out of a hat at random, and then throw darts at a dartboard to determine the ratios between them... I have so much respect for the people who work with and understand this stuff 😂😂😂

"As long as he doesn't eat it..."

If only we could be sure about that...

I'm watching a youtuber I like, watch a youtuber I like, watching a youtuber I like.

1:15:37 in the aerospace industry we work with surface roughness around 16 microns, and we’ll reject parts for having a scratch you can only see under magnification. it’s actually wild how important smooth surfaces are for any high heat/pressure application

My late father was certified to deal with 'special steels', which was the British euphemism for nuclear  hard in the 70s.

tbf, if i'm close enough to a nuclear weapon that is throwing Beryllium out, I have bigger problems then Beryllium poisoning

So, the answer to why nobody makes bouncy disks is because nobody wants to deal with beryllium unless necessary.

Tyler, I just wanted to say that ever since I discovered your channel( a couple weeks ago) your videos have taught me so much in the nuclear energy/general science fields.  Not only are they entertaining with your commentary, but you do an excellent job in explaining the science and safety involved with particular situations.  It's so refreshing to see your kind of channel on YouTube!  Best of luck and I hope your channel keeps growing!

The fume hood is operated at air pressure lower than the room it is in.  A blower constantly pulls air and contaminants out of the hood.

Fun fact about beryllium: In the late 90s(*) it was used in an alloy for components of some Formula 1 engines


*technically also in 2000, though teams were told in 99 to phase it out completely by the end of the 2000 season with a straight up ban from 2001 onwards

The filter being slightly below the window doesn't really matter much, the pressure in the fume hood is lower than the ambient pressure because there's a constant pumping of air out of it, this causes the air from the surrounding area to be sucked into the fume hood at all times, the flow of air is always inwards, and effectively no air from inside the chamber can exit. This constant flow of air also takes all but the heaviest particles with it, this is literally what they are designed to do, the amount of air that moves through one of those fume hoods is honestly shocking, it moves a tremendous amount of air and creates a very strong draft, especially when the door is very low.

I would deeefinitely be wearing a respirator mask for this. No one ever expects a piece of equipment to explode.

NileRed made a short where he did something similar to what you said you would have wanted to to see at 1:12:52
The sound it makes when it bounces between two discs is quite fascinating.

Actually, I’ve seen a video about an hardened steel anvil that was just as bouncy, if not more so than his glass. They took an antique harden anvil, milled down the surface to where it was flat again, and the hard and steel was ridiculously bouncy for the bearing.

the mould vacuum wasn't pulling it efficiently because he didn't put the entire system in a deep enough vacuum he just stopped it at ~1,000 microns and argon purged

The way he highlighted the strength of the metallic glass has me wondering what would happen if you tried to do the same technique to form a prince Rupert drop from it, honestly

My nuclear weapons knowledge grows by the day 😂
Great video as always, love the longer versions
