What was the third thing added in the experiment on Jay Leno? - thing

A few nights ago, there was an experiment with Jay Leno. It was an experiment of soap suds. The first detergent added hydrogen peroxide was very high (10 of the force) and the second thing easier, the color has. I do not know what third was added, but he made an incredible expansion glob of soap scum. It was really cool. My children are home schooled, and I want to have this experience in court as part of its chemical reaction unit. Thank you.
