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.
