What was in the cave water?

We found out that there was a specially modified enzyme in the cave water. An enzyme speeds up a chemical reaction. It breaks up large molecules into smaller ones. Enzymes are found in your body (stomach) and washing powders.

If we put liver or kidney containing the enzyme Catalase into Hydrogen Peroxide it breaks it down quickly into oxygen and water. Here is a video clip showing the reaction.
