I know the Drano Bomb is a pressure bomb, but because its produces Hydrogen (Or its supposed to) I think it would class as pyro, if the mod thinks I am wrong, by all means close this thread down. But I have seen alot of these bombs and instructions floating around on the internet. But I live in England and I dont think we have Drano here, I know that it is Hydrochloric acid that reacts with the metal, but the stuff over here just doesnt work. If anybody has tried this with English brands, can they please let me know which one, or whats wrong with our brands.

Draino is usually NaOH with aluminium shards.

It classes as pyro, but I have a rule about pressure devices: We do not speak of them. They are over done, unsafe, and boring. So, what happens when somebody mentions them? That's right! They get their thread locked and warned, because if they keep it up, they're gonna get banned.
