How to Make Stable Flash Powder
Here I shall show you how to make stable flash powder for all your uses in firework. It's not real flash powder, but the result is pretty good and not so sensitive like real flash powder. In my country, fireworks with flash powder inside of them are illegal, so I decided to make my own.
To make it you will need:
- Aluminum powder
- Potassium nitrate
You can find aluminum powder in paint stores or you can make it. Some stump removers are 100% potassium nitrate, but I bought mine online.
The ratio for the flash powder is 5/3/2 in weight. The aluminum powder is lighter than the rest, so it will all seem like the same amount.
Just throw everything together and start mixing in a pestle and mortar.
NEVER USE A BALL MILL FOR THE MIXING—IT CAN IGNITE THE FP.
After all the mixing, you should have a gray substance with no clumps.
Just do whatever you like. Just one thing—I'm not responsible for anything you do. I made this flash powder bomb.
