Mentos and Diet Coke Challenge
Two liter of Diet Coke
1. Place Diet Coke two liter OUTSIDE on a flat surface
2. Open Diet Coke
3. Add 7 Mentos
4. Run and watch the reaction.
Why do Mentos turn ordinary bottles of diet soda into geysers of fun? The answer is a little more complicated than you might think. Let’s start with the soda . . .
Soda pop is made of sugar or artificial sweetener, flavoring, water, and preservatives. The thing that makes soda bubbly is invisible carbon dioxide (CO2), which is pumped into bottles at the bottling factory using lots of pressure. If you shake a bottle or can of soda, some of the gas comes out of the solution and the bubbles cling to the inside walls of the container (thanks to tiny pits and imperfections on the inside surface of the bottle called nucleation sites). When you open the container, the bubbles quickly rise to the top pushing the liquid out of the way. In other words, the liquid sprays everywhere. https://www.stevespanglerscience.com/lab/experiments/original-mentos-diet-coke-geyser/
1 empty plastic bottle
Liquid dish soap
3% hydrogen peroxide
½ cup measuring cups
1 Tablespoon measuring spoon
Food coloring (optional)
large bin or tray to catch the foam.
1. Put on safety glasses
2. Go OUTSIDE with supplies
3. Carefully pour ½ cup of hydrogen peroxide into empty bottle.
4. Add a big squirt of dish soap and swirl gently to mix.
5. Add food coloring if you would like.
6. Place bottle in bin or set on tray
7. In the ½ cup measuring cup mix together one tablespoon of yeast and three tablespoons of warm water.
8. Pour the yeast mixture into the bottle and quickly step back.
9. Rinse the foam down the drain when it is time to clean up.
Observations and results-
You probably saw lots of bubbles and foam in this activity. What makes the foam appear? When the hydrogen peroxide comes into contact with the yeast it starts breaking down into water and oxygen. Oxygen is a gas and therefore wants to escape the liquid. The dish soap that you added to your reaction, however, traps these gas bubbles, forming a foam. The reaction continues as long as there is some hydrogen peroxide and yeast left. Once one of them runs out it stops making new foam. If you tried the activity without dish soap, the reaction probably will still made bubbles—but not foam. https://www.scientificamerican.com/article/make-elephant-toothpaste/
