HONOURABLE MENTION

ELEPHANT'S TOOTHPASTE

I was testing what elephant's toothpaste looks like and to see how hot it is.

Hypothesis

What is the best way to replicate a small amount of the world record for elephant toothpaste?, Mark Rober’s world record to be specific.

Research

Elephant's toothpaste is a warm foamy material caused by the quick release of the oxygen in hydrogen peroxide using potassium iodide or yeast mixed warm water as a catalyst. How quickly the reaction continues will depend on the absorption of hydrogen peroxide. Because it requires only a small number of ingredients to makes a "volcano of foam"is what it looks like if you use potassium iodide, this is a well known experiment for children to perform in school or at parties. The attempt is also known as the "marshmallow experiment", but is not the same as standard marshmallow  experiment.

Variables

When I started I used soap 3% hydrogen peroxide,dawn dish soap and normal yeast. That stayed the same the for the entire time except for ½ cup of 6% hydrogen peroxide and tablespoon of dish soap also the mix of warm water and yeast.

Procedure

First when you start you need 20 volume or 6% hydrogen peroxide ½ cup of that,1 tablespoon of dish soap (I use dawn ultra dish soap but you can use any type of dish soap) and warm water mixed with yeast.


 

Observations

Elephant’s toothpaste is a weird foamy substance that explodes.


 

Analysis

With all the variables I tried the best combination is ½ liquid clear 20 volume (6%) hydrogen peroxide,1 tablespoon of dish soap and yeast mixed with warm water.

Conclusion

The answer to the  hypothesis is the best way to make elephant toothpaste is with ½ liquid clear 20 volume (6%) hydrogen peroxide,1 tablespoon of dish soap and yeast mixed with warm water.

Application

This experiment was just to learn about chemistry and to have fun.

Sources Of Error

There are several sources for possible error. Some are:

  • using dry yeast
  • using 3% hydrogen peroxide instead of 6% (or 20 volume clear developer)
  • not using the right proportions
  • using soap that's not dish soap

Citations

If you were to make my version of elephant toothpaste you will need all these ingredients ½ liquid clear 20 volume (6%) hydrogen peroxide,1 tablespoon of dish soap and yeast mixed with warm water.
