Background Paper
For my Topic, I chose elephant toothpaste. I did the same experiment two years ago. Elephant's toothpaste is a very simple but very fun project to do. All it takes is an empty soda or water bottle, a funnel 6% hydrogen peroxide, Dawn dish soap, any color of food coloring you would like, a glass measuring cup, yeast, very warm water, and a spoon. But if you want to be really safe while doing the project, you may also need goggles, a lab coat or even a poncho, and some gloves.
When all of those ingredients are mixed, it creates a reaction. When the hydrogen peroxide is mixed with the yeast, it speeds up the decomposition of the hydrogen peroxide. When the oxygen spreads through the hydrogen peroxide and yeast mixture, it creates bubbles, and the Dawn dish soap that I told you about previously speeds up the foaming reaction from the decomposition.
The reaction from the mixture is considered exothermic, meaning it produces heat and even steam when mixed.
Many different types of scientific laws and theories are used for elephant's toothpaste, which include. The law of conservation of mass states that the matter of the experiment cannot be created or destroyed during the experiment. In my specific experiment, the hydrogen peroxide decomposes into water and oxygen gases, the total mass of the hydrogen peroxide dawn dish soap, water, and yeast. Equals the same weight of the end reactants.
Another type of law of thermodynamics. Especially the first law of thermodynamics, or the conservation of energy. The reaction of the elephant's toothpaste is exothermic. Which means it releases the energy as heat or steam, which makes the foam and bubbles from the elephant's toothpaste feel warm. It shows the transformation of potential chemical and thermal energy that goes into making the foam from the elephant's toothpaste.
Elephants' toothpaste also uses the laws of chemical kinetics. This field deals with the rates of chemical reactions. Luckily enough, elephant's toothpaste uses several different principles of kinetics. One of them is the yeast. The yeast plays a major role in the process of decomposition, and it speeds the decomposition of the hydrogen peroxide by lowering the activation energy without being consumed itself. It also uses the rate of reaction. The rate of foaming can be affected by the concentration of the hydrogen peroxide or the temperature of the mixture. Or maybe even the amount of yeast/dish soap added into the demonstration.
My experiment of elephants toothpaste mostly covers the field of chemistry. Because it demonstrates chemical reactions, decompostiotin and exothermic reactions. And some physical changes like the bubble and foam forming from the yeast mixing with the catalysis/yeast.
It even covers a little physics. Because of it activation from the yeast and the heat it releases. And also stem because it is a visually engaging for introducing fundamental science principles in school settings like science class or even a stem class.
All in all elephants toothpaste is a very intriguing topic with many different outcome. From the colors and the amount of foaming and also the amount of hydrogen peroxide and yeast added its a very versatile project that I am very excited about doing this year for Knights Of Science

Investigation Paper
For my Topic, I chose elephant toothpaste. I did the same experiment two years ago. Elephant's toothpaste is a very simple but very fun project to do. All it takes is an empty soda or water bottle, a funnel, 6% hydrogen peroxide, Dawn dish soap, any color of food coloring you would like, a glass measuring cup, yeast, very warm water, and a spoon. But if you want to be really safe while doing the project, you may also need goggles, a lab coat, or even a poncho, and some gloves.
First, you need to grab your safety gear. Which includes
- goggles
- a lab coat or even a poncho
- gloves
Then get your space prepped for the experiment.
Gather all of your ingredients needed, which include
- An empty bottle
- A funnel
- 6% hydrogen peroxide
- Dawn dish soap
- Food coloring
- Glass measuring cup
- Yeast
- Warm water
- And lastly a spoon.
First, you need to measure out ½ a cup of hydrogen peroxide and carefully pour it into the bottle, then you add a pretty decent amount of Dawn dish soap to the bottle and give it a swirl. If you would like to add color to the toothpaste, then you grab the desired color and also mix it into the bottle.
Grab your measuring cup again and make sure it's cleaned out. Into the measuring cup, you’re going to add 1 tablespoon of yeast and three tablespoons of lukewarm water. Mix that up for about 30 to 35 seconds.
Then you are going to get your bottle with your hydrogen peroxide, Dawn dish soap, and food coloring. And pour the solution into the bottle. But make sure that you quickly step back after pouring in the mixture into the bottle because the reaction is very quick. Don't forget that the experiments show an exothermic reaction. Which means it gets hot. So don't try to play with the elephant's toothpaste after the reaction.
The outcome of this experiment can vary by the amount of hydrogen peroxide or even by the amount of yeast used. For a bigger reaction, Try adding more yeast to hydrogen peroxide or even more hydrogen peroxide to yeast.
And if you mixed all of your ingredients in the right volumes. You should have gotten a very good reaction. And that is how you make elephant's toothpaste step by step from scratch.
