Foam production

Here is another experiment I have done with Alex. Foam production!
What you need:

  • Plastic water bottle
  • 6% or 9% hydrogen peroxide 100ml
  • Dish detergent
  • Food colouring
  • Half a packet of yeast dissolved in warm water

Pour the hydrogen peroxide into the bottle, add food colouring and about 1 tablespoon of dish detergent. In a separate cup mix the warm water and the yeast together. Pour the yeast water mixture into the bottle and watch the foaminess begin!
