I watched this earlier it was a fun watch as is most of Nile’s videos. I hope he does the follow up video and uses the oxygen reactive gas and makes the most dangerous pop rocks like he mentioned.
Does he ever talk about where he gets his gear? I know some of it is secondhand salvage... but I feel like there's some "family" component, or at least was at the beginning.
Early on there was a lot more salvaging and makeshift components, and "I know someone who knows someone". Nowadays, though, I think the channel gets more than enough support that the answer is "I spent $12k and bought it".
It's the reactor from htlab but it might be a re-brand [0][1]
Alibaba.com seems the place to be, although I keep seeing the same product (literally same picture) but under different brands so who know who actually makes this [2]
