What is the hypothesis for elephant toothpaste?

Here, our hypothesis is about hydrogen peroxide. So the experiment needs to change the proportion of hydrogen peroxide in the elephant toothpaste. An experiment also needs a control — a part of the experiment where nothing changes. The control could be no hydrogen peroxide (and no foam).

How does the elephant toothpaste experiment work?

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!

How do you do the foam experiment?

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.

What happens when you mix hydrogen peroxide and yeast?

What’s happening in there? 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 formula for elephant toothpaste?

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.

Overall Reaction: 2 H2O2 (aq) → 2 H2O (l) + O2 (g) Page 2 NCSU – Dept. of Chemistry – Lecture Demonstrations Kinetics Safety: Wear proper protective equipment including gloves and safety glasses when preparing and performing this demonstration. Concentrated hydrogen peroxide can cause burns.

Who invented elephant toothpaste?

YouTuber and former NASA engineer Mark Rober has destroyed the Guinness World Record for tallest-ever elephant toothpaste fountain. Rober and his team created the fountain of colorful, reactive foam using what amounted to a pseudo rocket thruster made of wood.

Can you touch elephant toothpaste?

Elephant toothpaste is safe to touch after 3 minutes. All materials can be safely disposed of in the sink, ensuring to wash with warm soapy water.
