Elephant Toothpaste......

This one's a classic. Nicknamed "elephant toothpaste" for the cylinder of foam it produces, this reaction shows the rapid decomposition of hydrogen peroxide. The reaction is produced by mixing concentrated hydrogen peroxide (mixed with a little bit of dish soap) and potassium iodide. When the potassium iodide is added to the hydrogen peroxide solution, it acts as a catalyst, rapidly breaking down the hydrogen peroxide into oxygen and water. The oxygen escapes from the beaker, quickly pushing out large amounts of foam from the dish soap. It looks like elephant-sized toothpaste.
