elephant toothpasteAnyone who's ever built a baking soda and vinegar volcano will tell you that there's nothing quite like the joy of creating a safe and educational eruption out of household ingredients.

But why stop at a tiny papier-mâché volcano? What if the eruption could be just as safe, only, say, ten times larger and less messy to boot.

The Elephant Toothpaste experiment is all of that and so much more. Though there are many possible catalysts (listed at the link above), the primary goal of any Elephant Toothpaste experiment is to make hydrogen peroxide decompose as fast as you possibly can.

Find the right ingredients and the result is nothing short of magical.
