My dad talks about making this stuff as a teen. It started with a chemistry kit that came with all sorts of dangerous things they would never in a million years sell targeting to a kid again. This peaked his interest in chemistry and he came across nitrogen triiodide while researching at a library with actual paper books lol. The ingredients were of no difficulty to obtain back then. They made this stuff and had fun setting some of it off. But he then told me that the next day he and his buddy thought let’s go set off some more. But he thought about it and they both said but what if the stuff on the edge of the jar has dried? Yes they made a fairly big sample. They were too nervous to open it so he told me he dug a hole and carefully moved it and hurried it. It sucks that people do bad things with chemicals as I would love to play around with things like this carefully in a safe setting without risk of other being hurt.
