The Elephant Toothpaste experiment is a fun and educational chemistry demonstration that showcases a chemical reaction producing a foamy substance resembling toothpaste. Here's a breakdown:

Materials:
1. Hydrogen peroxide (H₂O₂)
2. Yeast (or potassium iodide as a catalyst)
3. Dish soap
4. Food coloring (optional)

Procedure:
1. Mix hydrogen peroxide with dish soap in a container.
2. Add food coloring for visual effect (if desired).
3. Activate the reaction by adding yeast (or potassium iodide).
4. Observe the rapid formation of foam, resembling overflowing toothpaste.

Science Behind It:
Hydrogen peroxide decomposes into water and oxygen gas when the catalyst (yeast or potassium iodide) is added.
The released oxygen gets trapped in the soap bubbles, creating a large volume of foam.
This reaction demonstrates catalysis, gas production, and chemical decomposition in an engaging way.
