Baby Elephant Toothpaste Cool Science Experiment
In this fun and easy experiment, we are going to make a cool concoction called baby elephant’s toothpaste by creating a chemical reaction.
- Plastic water bottle
- Dish Soap
- Yeast Packets
- Measuring spoons
- Hydrogen Peroxide
- Food Coloring
- Warm water
- Cake pan, tray, or other vessel to catch the foam eruption
- Small container of bowl
- Pour one half cup of hydrogen peroxide into the water bottle.
- Squirt a few drops of dish soap into the water bottle.
- Add several drops of the food coloring of your choice into the water bottle.
- Now in a separate bowl, mix one teaspoon of yeast with two tablespoons of warm water. The yeast mixture will be a little clumpy.
- Make sure you have placed your water bottle into the cake pan to contain the eruption.
- Now pour the yeast mixture into the water bottle and enjoy watching the chemical reaction occur.
How it Works:
In this chemical reaction, the yeast acts as the catalyst. A catalyst is the substance that increases the rate of the chemical reaction without being consumed itself. The yeast catalyzes and causes the hydrogen peroxide to release oxygen molecules. The resulting foam that squirts from the bottle like toothpaste is the tiny oxygen bubbles released during the chemical reaction.
Make This A Science Project:
Try different amounts of yeast. Try different temperatures of water. Try different sized and shaped bottles.
