Is Elephant Toothpaste a good science fair project?
With just a few simple ingredients, you can make something that looks like toothpaste being squeezed from a tube—but so big, it must be for elephants! This activity is not recommended for use as a science fair project.
How do you make elephant toothpaste science fair project?
Instructions
- Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water.
- Pour 1/2 cup hydrogen peroxide into the empty bottle.
- Add a few drops of food coloring into the bottle.
- Add a squirt of dish soap into the bottle.
What is the hypothesis for elephant toothpaste?
Elephant toothpaste explained Either will cause the hydrogen peroxide to break down very quickly. The dish soap and food coloring aren’t needed for the reaction. But they create the show. As hydrogen peroxide breaks down into water and oxygen, the dish soap will catch the liquid and gas to form bubbles.
How do you explain the elephant toothpaste experiment?
The oxygen gas forms bubbles. These bubbles would usually escape from the liquid and pop quickly. But, adding a little dish soap provides additional surface tension, allowing the bubbles to get trapped and creating lots of foam. This foam looks like a giant squeeze of toothpaste—almost big enough for an elephant!
What is the conclusion of the elephant toothpaste experiment?
Our hypothesis stated that the trial using the 30% solution would be the fastest and it was proven correct. It was the fastest because it had more pure hydrogen peroxide making it have more oxygen when broken down and pushing the foam out faster.
What is the conclusion of the Elephant Toothpaste experiment?
What causes elephant toothpaste to react?
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.
What causes Elephant Toothpaste to react?
What is Devil’s toothpaste ingredients?
Devil’s Toothpaste is really the same as the famous Elephant Toothpaste experiment, just executed with higher concentration hydrogen peroxide. In this case, [Integza] is using 50% hydrogen peroxide combined with potassium permanganate as a catalyst.
What are facts about elephant toothpaste?
– a catalyst can make a reaction occur, and the reaction can be rapid and quite showy. – potassium iodide, manganese dioxide and potassium sulfate are catalysts for hydrogen peroxide – there’s a lot of oxygen hiding in hydrogen peroxide, enough to really make things move – when soap has lots of oxygen released into it, it turns into soapy foam
What is the science of elephant toothpaste?
‘Elephant’s Toothpaste’ because the large stream of foam looks like toothpaste big enough for an elephant! Hydrogen peroxide is a molecule made up of hydrogen atoms and oxygen atoms. It can be expressed using the chemical formula, H 2 O 2. Under the right conditions, hydrogen peroxide will
