Introduction

Elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide -a chemical compound form by one single bond-, it is often use in classroom demonstrations. This reaction gets its name from the ingredients. First, hydrogen peroxides are big in the toothpaste industry right now. Second, toothpaste can be thought of as a soap because it cleans your teeth. It’s a fun, simple project that everyone can accomplish.

What is the Elephant Toothpaste?

The elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide. This is often used for classroom demonstration because it requires only a small number of ingredients and makes a "volcano of foam". This is sometimes known as the "Marshmallow Experiment".

Materials:

- A plastic bottle (we use a pint).

- One cup (to measure the amounts).

- Safety glasses.

- A funnel.

- Hydrogen peroxide (also known as hydrogen peroxide) of 20 vole. The can find in drugstores or salons.

- Yeast.

- Hot water.

- Liquid detergent.

- Food coloring (color that you like).

Procedure:

With safety glasses put, we take about three quarters of a cup of hydrogen peroxide in the bottle (the glasses are absolutely necessary, since hydrogen peroxide can irritate the eyes).

Then, add a dash of food coloring (about 8-10 drops) and a tablespoon of liquid detergent. Gently move the bottle to mix substances.

Meanwhile, in a small cup, mix a tablespoon of yeast with three hot water (rather warm, if the experiment does not work too hot) and stir well for 30 seconds.

Finally, pour the contents of the bowl into the bottle ...and the show begins!

Explanation:

The result of this experiment is given through an exothermic reaction:

2H2O2 --------- > 2H2O + O2

This reaction is triggered by yeast, which contains an enzyme called “catalase " , which breaks down hydrogen peroxide ( H2O2) into water ( H2O ) and oxygen ( O2).

This oxygen is released to do so quickly, so a lot of bubbles in their attempt to "escape”. These bubbles are so many and they are so fast, wanting to go out all at once, make this kind of “elephant toothpaste “.

Conclusion

According to our experiment, a chemical reaction took place. A massive foam erupted for the glass jar and flowed out continuously. After we put in practice this experiment we realized that what caused this reaction was actually the potassium iodide and yeast. The objective of the experiment is to release the surplus Amounts
