The latest experiment from Rick Crosslin, MSD Wayne Township Scientist in Residence, appears to be toothpaste fit for an elephant, but in reality, it’s a giant foaming reaction using chemical elements.

With just a few ingredients you can make something that looks like foamy toothpaste being squeezed from a tube, but so big that it looks sized for an elephant!

Each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst; a catalyst is used to speed up a reaction. 

The elephant toothpaste demo is one of the most popular chemistry demonstrations, in which a steaming tube of foam keeps erupting from its container, resembling a smooshed tube of elephant-sized toothpaste. The classic demo uses 30% hydrogen peroxide, which is not safe for kids, but there is a safe version of this demonstration that is still very cool.
