What does the dish soap do in elephant toothpaste?

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!

Can you use 3% hydrogen peroxide for elephant toothpaste?

What is Elephant Toothpaste? This large demonstration uses hydrogen peroxide (H2O2), sodium iodide (NaI) and soap. … That is usually 3% hydrogen peroxide, and your local salon probably uses 6%. The 30% hydrogen peroxide is not something you would put on a cut or scrape, but it works perfectly for this demonstration.

Why is yeast used in elephant toothpaste?

The foam you made in this classic Elephant’s Toothpaste reaction is extra-special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst; a catalyst is used to speed up a reaction. It quickly broke apart the oxygen from the hydrogen peroxide.

What is the science behind elephant toothpaste?

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. The soapy water traps the oxygen, creating bubbles, and turns into foam.

Can Elephant Toothpaste kill you?

The original elephant toothpaste reaction, which uses a much higher concentration of hydrogen peroxide, can cause both chemical burns and thermal burns. 1 While it produces a larger amount of foam, it’s not safe for kids and should be performed only by an adult using proper safety gear.

Can you use hair developer for elephant toothpaste?

A tray to place the bottle in to catch the foam (I used an aluminum tray.) ½ cup of 6 percent hydrogen peroxide or 20 volume hair developer. (You can purchase the hair developer from Amazon.com or at Sally Beauty Supply. I used Matrix 20 volume developer.)

Is Elephant toothpaste hot or cold?

The 500 ml of water has a heat capacity of around 2100 J/K. So, the solution gets about 12 K hotter.

Does elephant toothpaste get hot?

The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water and oxygen. The bottle felt warm to the touch because this was an exothermic reaction in which energy is given off in the form of heat.

What percent of hydrogen peroxide is best for elephant toothpaste?

What You’ll Need:

  • A clean 16-oz plastic soda bottle.
  • 1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution; you can get this from a beauty supply store or hair salon)
  • 1 Tablespoon (one packet) of dry yeast.
  • 3 Tablespoons of warm water.
  • Liquid dishwashing soap.
  • Food coloring.
  • Small cup.

Common sense warning: Do not eat or brush your teeth with elephant toothpaste!

What is Devil’s toothpaste?

Can you play with 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!

What is the best catalyst for elephant toothpaste?

The secret ingredient is actually sodium iodide, which acts as a catalyst (something that speeds up a chemical reaction, and in this case, it’s the decomposition of hydrogen peroxide). When hydrogen peroxide (H2O2) decomposes, it breaks down to form water (H2O) and oxygen (O2).

What is the conclusion of elephant toothpaste?

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.

Why does elephant’s toothpaste lose mass?

Hydrogen peroxide is unstable and breaks down over time into water and oxygen gas, but the catalyst potassium iodide speeds up that decomposition into a matter of seconds.
