Elephant Toothpaste

It’s time to turn your home into a laboratory. Learn about static energy and re-create homemade lightning. See a rocket ship launch with the science of chemical reactions. Here are 17 experiments to get those brain gears churning — click through to see them all. We’ve even ranked the messiness factor from one to five sponges so you know what to expect.

It’s A Lesson In: Chemistry. The magic of this experiment is in the yeast, which breaks hydrogen peroxide down into water and a lot of oxygen. All that air then gets trapped by the soap water and then explodes forth in the form of a foamy volcano. Ask your scientist to touch the bottle; it will be warm because energy is being released. You’ll want to set down a cookie sheet or mat to catch the mess.
