ELEPHANT TOOTHPASTE

The bottle with 120 volumes of H202 expanded faster than all the other bottles with lower volumes. The 20 volumes re-acted slowly. It took about 3 minutes to expand over the top of the bottle.

I predict that as we use more hydrogen peroxide, the elephant toothpaste will expand.
