One time I filled a Mylar balloon with H2 by electrolysis. It floated very nicely but I was too cowardly to keep it in the house. It made a nice fireball when lit outside but no particularly notable explosion. Encouraged by this I filled one of those grocery store vegetable bags with H2 + O2 from the same electrolysis setup (combine both outputs this time). Stoichiometric mixture! The boom was so loud I thought it was going to break my windows from about 20 feet away. |
