Is this edible or is it just a science experiment?

This is just a science experiment. Do not eat it! This is the trick: The hydrogen peroxide is a chemical compound used sometimes as an antiseptic. Its molecules are very similar to those of water but they contain more oxygen (H2O2). When you mix the soap with hydrogen peroxide and add potassium iodide (non-toxic, even added to table salt to make it "iodized"), the peroxide molecules break down very quickly into oxygen (a gas) and water. The soap dissolves in the water and the oxygen tries to escape, and in doing so, it produces foam. The escaping oxygen makes the tiny soap bubbles move. So, if you eat it you will be eating soapy water with salt!
It is safe enough to try it in a classroom!

ngfcake: You sure know your science!
Liz: That would really be cool in the classroom, the kids would be so surprised! I know I was!
