Elephant Toothpaste: A Fun Science Experiment

Decent Essays

Elephant toothpaste is such a fun science experiment. Elephant toothpaste is very unique with its name and what it is. It really does look like elephant toothpaste so the key factor in this science experiment, is the random and fun factor. It is a very common experiment done in the classroom. You only need a few easy to find ingredients to make the foamy substance. The foamy reaction is caused by the rapid decomposition of hydrogen peroxide. The supplies you will need are:
1. 16 ounce plastic bottle
2. ½ cup hydrogen peroxide 6%
3. 1 Tablespoon of dry yeast
4. 3 Tablespoons of warm water
5. Liquid dish soap
6. Food coloring
7. Small cup
8. Safety goggles
9. Tray
You will begin my putting your safety goggles on because the hydrogen …show more content…

The second step would be to add your favorite food coloring. You could get creative and add more than one color to make rainbow toothpaste. Next you will need to add the dish soap, 1 tablespoon of it to be exact. In a separate bowl mix warm water and the yeast for at least 30 seconds. Make sure to mix it well so the chemical reaction can start immediately. Now pour the warm water with the yeast mixed in into the bottle and watch the magic happen! The Foam is so cool! The foam that was produced is special because each bubble is filled with oxygen. The catalyst is the yeast and it helps remove the oxygen from the hydrogen peroxide. Yeast is a microorganism that is alive. We used Baker’s yeast and is the name of the strain of yeast used in bread dough to rise. Hydrogen Peroxide is a clear liquid which can bleach clothes and can be used to kill germs in skin cuts and scrapes. Because it did this exceptionally fast it created a lot of bubbles. If you could be close enough to the bottle you could have felt that the bottle heated up. This is because it caused an Exothermic reaction. This is means it not only created the bubbles it created heat. Putting the live yeast with the
