MakerSpace Activity: Fizzing Bath Soaps

This activity involved a bit of preparation but was popular and had links to the Science curriculum in the Year 2 mixtures unit and in Maths with measurement. We set it up as a series of stations which students had to move through, following the instructions at each stage.

  1. Take a bowl.
  2. Add one tablespoon of Epsom salts.
  3. Add a quarter cup of bicarb soda.
  4. Add a couple of drops of food colouring.
  5. Add one drop of essential oil.
  6. Add acidulated water (1 cup of water with one tablespoon of lemon juice added) very slowly (We used a spray bottle), mixing between each addition until it looks like damp sand.
  7. Mold into patty pans.
  8. Let sit overnight until hard.
