Soapy sea foam

  • Place 2 tablespoons of washing up liquid and 2 tablespoons of water in a large bowl.
  • Add 1 tablespoon of cornflour and a squirt of washable poster paint (you choose the colour!)
  • Mix together using an electric whisk for a couple of minutes at high speed.
  • Soon, you will have lots of soft bubbly foam ready to play with.
  • You could hide some shells and toy fish beneath the foam and have an ocean treasure hunt.
