1: Put safety glasses on
2: Using a 50ml grad cylinder, measure 118 ML of hydrogen peroxide 12%
3: Add a large squirt of dish soap
4: Then add a few drops of food coloring
5: Mix
6: In a separate container, add 14.3 grams of yeast and 42.9 grams of warm water, then mix
7: Pour the yeast mixture into the bottle
8: Step back.

If we add a stronger percentage of Peroxide the reaction will be more explosive and vigorous.

What if we used 12% Hydrogen Peroxide contrary to the 3%?

# data[].attributes.body
When we first tested the Elephants Toothpaste Experiment, we used the following:
1: Yeast
2: 3% Hydrogen Peroxide
3: Dish soap
4: Food coloring

The result was very underwhelming from what most expected but that is okay, we still were able to witness the Chemical reaction. The food coloring did not do much we could have added a more considerable amount; however the yeast combined with the dish soap created a foamy substance spewing out of the bottle.

Ways to identify a Chemical reaction in comparison to a Physical change as follows:
1: Drastic change in temperature/heat release
2: A change in color due to reaction
3: Bubble Formation
4: Expansion
5: Creation of a new Substance
6: Change in odor

The catalyst is very important in this reaction. By simple terms, a catalyst is a substance (chemical) that can be added to a reaction to further accelerate the process. The decomposition of the H2O2 would be horrendously slow if no catalyst was added.

A decomposition reaction is when a compound element is broken down or decomposed into multiple other compounds.
The decomposition in this reaction is the breaking down of Hydrogen Peroxide.

Having this be an exothermic reaction, this means that instead of absorbing energy (like an endothermic reaction), it releases the energy. This is evident when the decomposition occurs and the reaction becomes heated.

Elephants Toothpaste can be described as an exothermic, chemical reaction caused by the decomposition of hydrogen peroxide.
