We tested if a coke bottle could be used as a good storage for the Oxyhydrogen. This, however, didn’t work out well. You can hear the gas escape out of the bottle at 1:06. The second “explosion” is just the rest that’s left. The oxyhydrogen was generated by a Smack’s Booster. Do not try this at home, this is extremely risky and you can get seriously injured by the explosion.
