This lab is a crowd pleaser! Kids will make foamy "elephant toothpaste". This one should be done outside or in the sink! Kids will explore the chemical reaction, and experiment with what type of container makes it foam the most.
This lab requires hydrogen peroxide, which is a skin and eye irritant. Adult supervision is required.
This lab has an option for 6% hydrogen peroxide and 9% hydrogen peroxide. The higher the percentage, the more aggressive the foam is.
