How do you do the elephant toothpaste trick?

In a measuring cup mix together one tablespoon of yeast and three tablespoons of warm water. Stir for about 30 seconds. Pour the yeast mixture into the bottle then quickly step back, and watch your reaction go!

What makes elephant toothpaste explode?

Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container.

What activates elephant toothpaste?

The sodium iodide reacts with the hydrogen peroxide (H2O2) by removing an oxygen atom. This essentially produces water and oxygen gas (H2O + O2). The oxygen gas produced gets trapped in the soap which produces the big ball of foam. The reaction produces oxygen gas, water and iodine.

How do you make elephant toothpaste kid friendly?

Make Elephant Toothpaste Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Swish the bottle around to mix the ingredients. Set the bottle in a sink or outdoors or some other place where you won’t mind getting wet foam everywhere.

What happens when you mix hydrogen peroxide and yeast?

When yeast was added to hydrogen peroxide, a chemical in the yeast causes a reaction in which the hydrogen peroxide breaks apart to form oxygen gas and water. The oxygen was in the bubbles you saw. This reaction causes the temperature to go up.

What is the best catalyst for elephant toothpaste?

Suitable catalysts include yeast, manganese dioxide, “rusty” manganese metal and potassium iodide. Catalase, an enzyme present in our blood, also catalyzes the decomposition of peroxides, including hydrogen peroxide, which would otherwise be harmful.

How do you make exploding foam at home?

Here’s How: Carefully pour the hydrogen peroxide into the plastic soda bottle. Add 10 drops of food coloring to the plastic soda bottle. Add 1 T. of dish soap to the plastic soda bottle, and swirl the bottle around to mix everything up.

Can you touch elephant toothpaste?

It is safe to touch because all that foam is just soap, water and oxygen. Let your kids have some fun with the foam too. Just be sure to have a towel handy!

How do you make a big foamy snake?

You only need a few materials to make a foam volcano.

1. 1/2 cup of liquid hydrogen peroxide.
2. 10 drops of liquid food coloring.
3. 1 tablespoon of liquid dish soap.
4. 1 packet of dry yeast.
5. A 16-ounce plastic soda or water bottle OR a bucket that size.
6. A small cup to hold your yeast and at least 3 tablespoons of warm water.

How do you make elephant toothpaste step by step?

Elephant Toothpaste Experiment Instructions Step 1 – Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water. Step 2 – Pour 1/2 cup hydrogen peroxide into the empty bottle. You’ll see here that we have two bottles.

Why is the elephant toothpaste experiment so dramatic?

The elephant toothpaste experiment is so dramatic because the reaction happens quickly. Hydrogen peroxide breaks down naturally over time, especially when exposed to light, but in this reaction the yeast causes that breakdown to happen much quicker. This is because yeast is a catalyst – a substance that can help the reactants react

What is the chemical equation for toothpaste reaction elephant toothpaste?

Elephant Toothpaste Chemistry. The overall equation for this reaction is: 2 H2O2(aq) → 2 H2O(l) + O2(g) However, the decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion.

What happens when you mix toothpaste and foam together?

Mix two solutions together and you get an amazing eruption of foam that looks like a giant stream of toothpaste exploding from the cylinder. Some people refer to this foam as Elephant’s Toothpaste (when the reaction is in action, this name will totally make sense).
