Of course, when I found out from "The Golden Book of Chemistry Experiments" that heating wax and sulfur together made a far more pungent gas, I thought that this would be a very funny thing to fill balloons with. I was planning on moving my operation outside but didn't see the harm in filling a balloon or two in my room. It turns out that producing larger quantities are a very bad idea in a small bedroom. My mother was an RN and found out that what I was doing was not only very irritating but was actually dangerous. So that was the end of that. Especially after my little brother had burned off his eyebrows with some flash powder that I had made a week or two before.
Very cool book. Thanks for the link. I used pool acid and aluminum foil for my hydrogen generator. 3 balloons would easily raise an M-80. Cotton string soaked in potassium nitrate makes a durable slow fuse to gain more altitude.
