Junior Scientist

Hi, everyone! My name is Fabian and I am this week’s ‘Junior Scientist’.

My experiment is called ‘Elephant Toothpaste’. You must have your parent’s permission to do this experiment. Elephant Toothpaste is a foamy experiment that looks like giant toothpaste fit for an elephant.

 

This is me setting up my experiment items! The materials I used is on the table.

This is me pouring the dry yeast mixture into the bottle which contains the hydrogen peroxide.

This is the ending result of my experiment on Elephant Toothpaste.

 

Materials:

  • Hydrogen Peroxide (6% solution (20-vol)) (1/2 cup)
  • Dry Yeast (1 tablespoon (1 sachet))
  • Food Colouring (Optional) (8 drops)
  • Bottle/Container
  • Detergent/Liquid Dish Washing Soap (1 tablespoon)
  • Safety Goggles
  • Funnel (Optional)
  • Small Cup
  • Warm Water (3 tablespoons)
  • Gloves

Method:

  1. Wear safety goggles and gloves.
  2. Ask an adult to help pour in the hydrogen peroxide into an empty bottle/container (using a funnel).
  3. Add food colouring and detergent to the bottle/container.
  4. Combine warm water and dry yeast in a small cup and stir thoroughly.
  5. When ready, pour the mixture into the bottle/container (using a funnel) and step back.
  6. Watch it grow and pour out like Elephant Toothpaste!

Notes:

  • Hydrogen Peroxide is dangerous (poisonous), so make sure you ask an adult to help you pour it in.
  • Make sure you do the experiment on a surface that can be cleaning easily.
  • Wear gloves and goggles for protection!
  • You don’t have to use food colouring or a funnel, but it might be a good idea to use a funnel to make it easier.

    I have never heard an experiment call Elephant toothpaste.
