The elephant toothpaste demonestration is one of the most significant and popular concepts of chemistry. So in this blog, you will learn what is the mechanism of how steaming a tube of foam continuously erupts from the container. So you will also come to know how it resembles a smoosh tube of elephant-sized toothpaste.

However, the earlier demonstrations use 35% of hydrogen peroxide which is not safe for kids.

When you are with me then how is it possible I will not clear you an elephant toothpaste. So here I will show you a safe version of the demonstration that practically works. Therefore make sure it goes like this:

Materials for elephant toothpaste

  • Take an empty 20-ounce plastic bottle (or another container)
  • You can take 3% hydrogen peroxide solution (available at nearly any store)
  • A packet of active yeast (from the grocery store)
  • Liquid dishwashing detergent (such as Dawnâ„¢)
  • Warm water
  • Food colouring (optional, but it looks nice)

    • Make Elephant Toothpaste

  • Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food colouring 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.
    • ElephantToothpaste
  • In a separate container, mix a packet of active yeast with a little warm water. Give the yeast about five minutes to activate before proceeding to the next step.
    • ElephantToothpaste
  • When you are ready to do the demo, pour the yeast mixture into the bottle. The reaction occurs immediately upon the addition of the yeast.

    • Can I touch the foam?

    The reaction typically breaks down the hydrogen peroxide so you are left with mostly just soapy water and yeast. There can, however, be un-reacted peroxide which could irritate skin and eyes. For that reason, it is recommended that you do not touch the foam.

    (If you use the 3% hydrogen peroxide found in most pharmacies, then the foam can be touched safely.)

    How It Works

    Make sure you have to take Hydrogen peroxide {) which is a reactive molecule. And readily decomposes into water (H2O) and oxygen:
