  • 150ml 6% hydrogen peroxide liquid
  • 1 Tablespoon (one packet) of dry yeast
  • 3 Tablespoons of warm water
  • Washing up liquid
  • Food coloring
  • Small cup
  • Safety goggles

  1. Carefully pour the hydrogen peroxide into the bottle
  2. Add 8 drops of your favorite food coloring into the bottle
  3. Add about 1 tablespoon of washing up liquid into the bottle and swish the bottle around a bit to mix it
  4. In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds
  5. Now the adventure starts! Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!

  • Always remain aware of your surroundings and follow local COVID-19 advice, including the Hands / Face / Space / Ventilation guidance.
