The sodium iodide reacts with the hydrogen peroxide (H 2O 2) by removing an oxygen atom. The 30% hydrogen peroxide is not something you would put on a cut or scrape, but it works perfectly for this demonstration. That is usually 3% hydrogen peroxide, and your local salon probably uses 6%. This is 10 times stronger than the hydrogen peroxide that you have in your medicine cabinet. The hydrogen peroxide used in the demonstration is 30% hydrogen peroxide. First we pour in the hydrogen peroxide, then the soap and finally the sodium iodide. This large demonstration uses hydrogen peroxide (H 2O 2), sodium iodide (NaI) and soap. So if you want to see it again just come on in! Our EXTREME Scientists do the Elephant’s Toothpaste demonstration in our Extreme Science Theater located on the lower level of the science center. It is, of course, not toothpaste so please do not try to brush your teeth with it! The kids safe version below is harmless but certainly wouldn’t taste very good. It is so big that only an elephant could use toothpaste this large. This demonstrations is called Elephant’s Toothpaste because the chemical reaction produces a large foamy mess that looks like toothpaste squirting out of a tube.
