WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments
- This experiment demonstrates the eruption of an iron volcano.
- First let’s prepare a suitable site for volcano.
- Pour 4-5 spoons of sand in a hill-like shape on a fire-proof surface.
- Make a socket on the top the sand hill.
- Weight out equal amounts of iron powder and potassium nitrate. Mix the components thoroughly.
- Place the mixture into the socket.
- It is hard to ignite an iron-potassium nitrate mixture. It could stand the action of a burner flame for a while. One of the ways to overcome this difficulty is using red-hot coal. Heat the piece of coal with a gas burner till it becomes red-hot. Put the coal on top of the reagents mixture.
- The active burning begins. The release of gold sparks and white smoke is observed. The substances are heated to a bright-yellow color and resemble lava.
