Try this wacky and easy to do experiment at home with your kids, and watch colorful tubes of foam erupt into elephant toothpaste!
The first experiment, according to Mark Zabawa, associate professor of chemistry and biology at ILCC's Emmetsburg campus, included mixing potassium iodide and hydrogen peroxide with detergent to create a foam resembling "elephant toothpaste." The second included using leaf blowers to demonstrate kinetic energy. [3]
Elephant toothpaste [ edit ] no, it isnt actually toothpaste for your elephant, thats just the name. elephant toothpaste is just a reaction caused by the decomposing of hydrogen peroxide, also when doing this experiment be careful, the fizz is hot.
