WATER STAR A FIRE

Ammonium Nitrate - 14,0 grams
Ammonium Chloride - 1,5 grams
Zinc Dust - 34,5 grams

Note that as soon as all the components are mixed, it will become extremely water sensitive!
Even a tiny amount of water will ignite the mixture. You must use this composition immediately after it is made - DO NOT STORE IT - for any length of time, and do not mix it with other chemicals.
It's recommended to only mix this formula & conduct this experiment
outside.

Take about a teaspoon full of the mixture and make a small pile of it on the ground. Make sure the ground is dry and that there are no flammable materials nearby (dry grass, paper, etc.).
Press a little indentation into the top of the pile and add a drop of water.
QUICKLY STAND BACK! In a second or so it will bubble, hiss and smoke, and instantly burst into a blue-green flame.

WARNING

Don't store this mixture, it will eventually absorb enough water from the air to ignite on its own.
Use all that you make each time.
Do Not make large quantities at one time.
This is NOT something you want to mix on a rainy day.
