Re: 4th of July Rocks
Actually there are three ingredients in black powder or gun powder. They are potasium nitrate (salt petre), sulfur, and charcoal. When I was a kid I made my own gunpowder and it was a real blast (pardon the pun) to actually watch it burn. I wanted to make my own model rockets but never made the right mixture for the fast burn rate I needed. I would not recommend anyone make this without being extremely careful in where you ignite it.
