| The basics of pyrotechnics |
| gunpowder materials 1. potassium nitrate (saltpeter) 2. sulfur 3. charcoal procedure 1.mix 75% saltpeter with 10% sulfur and 15% charcoal |
| rocket propellant materials same as gunpowder procedure 1. 72% saltpeter 24%charcoal 4%sulfur |
| notes: the finer the powder, the faster it burns and the better it performs. to make a pop or a small explosion, pack powder into something and seal it tightly, then make a tiny hole and insert the fuse. gunpowder or other extremely flammable material burning inside a sealed space will cause it to explode. using this principle, u can make a potato gun powered by hair spray. www.spudlauncher.com to make rockets, just pack propellant into a tube and let it harden. afterwards, make a hole in the center of the propellant. these are called core burners. burning propellant from the core will make it burn faster with more power, causing it to fly. |
