Colour Changing Water

Watch the children’s faces when they discover that they can make the colour in the water disappear! All you need to make this happen is:

  • 3 clear cups
  • 3 different food colourings
  • A little bit of bleach
  • Water
  • Dropper
  • Gloves
  • A stirrer

First, half fill each of the 3 cups with water and add a different colour food colouring to each. Then, using a dropper, add a few drops of bleach to each cup. Using the stirrer, stir away the colour.

Please ensure the safety of the children doing this experiment as it involves bleach. Make sure there is close adult supervision at all times and use the appropriate protective equipment (we used gloves).
