Make a motion ocean!

What you'll need

  • Clear jar with lid
  • Water
  • Blue food colouring
  • Glitter
  • Baby oil
  • Plastic floating toy

How to do it...

  1. Fill the jar halfway with water.

  2. Add drops of food colouring until you like the colour you see. Shake in some glitter.
  3. Pour in baby oil until the jar is three-quarters full.
  4. Place a floating toy on top of the oil, then screw on the lid tightly.

  5. Shake the jar gently to set your ocean in motion.
How does it work?
Water is denser than oil. Plus, the two liquids never mix. So when the water moves, it pushes the oil around, making shapes like waves!
