It's half-term week, so myself and my daughter Sophie have been generally messing around, but wanted to try out a safe version of the Elephant's toothpaste experiment.

This is a bit of a dribble compared to the strong concentration of chemicals used in the normal demonstration, but it is a lot safer and you can happily do this in the kitchen without any thing blowing up/getting permanently burned/stained/etc

Here's the sciencey bit behind the experiment: The yeast acts as a catalyst to remove the oxygen from the hydrogen peroxide. Since it does this very fast, it creates lots of bubbles. The reaction is also exothermic - it creates heat as well as foam.

Much better explanations can be found online with the help of google, we just looked up how it was done after seeing it a few times :)
