Clever celery

Getting ready

Celery can be really clever – all plants can in fact! Let's see what happens when we leave celery in coloured water...

First, ask an adult to help you get together these things:

  • celery sticks with the leaves still on
  • chopping knife
  • chopping board
  • large plastic cup or glass
  • 1 bottle of food colouring (darker colours work better)

If you want to make a walnut boat to float in the coloured water you'll need these things too:

  • walnut shells 
  • nutcracker
  • paper
  • felt tips
  • cocktail sticks
  • strong glue or plasticine
