Elephant toothpaste type of reaction
Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide (H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. Because it requires only a small number of ingredients and makes a "volcano … WebMar 18, 2024 · The elephant toothpaste reaction is just the speeding-up of a chemical reaction that usually happens very slowly. Hydrogen peroxide ― that antiseptic liquid that usually comes in a brown bottle and bubbles up when you put it on a cut ― is a chemical compound that's made of two hydrogen and two oxygen molecules bonded together.

WebLooks like a variation of elephant tooth paste. Whatever that mystery liquid is (I suspect hydrogen peroxide but I’m not for certain) caused a bunch of hydrogen and oxygen to be released. The hydrogen is less dense than the surrounding air and so it floats and takes the toothpaste with it similar to a blimp. Cheshie_D • 2 yr. ago
