How to Make Flash Powder out of simple household items
•Sugar
•Salt Peter (Potassium Perchlorate)
Step
1Go to a local hardware store or pharmacy to purchase Salt Peter/Potassium Perchlorate, make sure its the purest possible (Stump removers and fertilizers works best). There are now some new products that are 99.9% pure Potassium Perchlorate, also make sure the package you buy is powdery, if its not then crush it until it is fine powder.
Step
2I will not give you exact measurements for this powder, however you will need a mixture of half sugar/charcoal and half Potassium Perchlorate. Mix this slowly and carefully, make sure if you mix these two chemicals in a plastic bag or anything of the sort first spray it down with anti-static spray. You must mix these two products until the powder is grey and as fine as possible. To make this more explosive, add 10% sulfur during the mix which will create a moderate burning fuel, be very careful with sulfur as it is highly sensitive to friction and impact.
Step
3Once you have mixed the two(three) substances you can now add another chemical into the mix which will act as an even greater oxidizer. Take a sparkler and shave it until all the stick is turned into powder (or however much you need depending). When heated these chemical byproducts will react with each other creating an explosion.
.Tips & Warnings
Make sure you measure both the sugar and Potassium Perchlorate as precise as possible.The legal limit for flash powder in fireworks is 50mg, don't be caught with over this limit.Be very careful when mixing the sunstances.The finished product and many of the chemicals used are high flammable and explosive, handle with care
