Summary: Simple science experiments using kitchen and pantry items are fun to do and a great way to help your children learn. Young children are naturally curious and will thoroughly enjoy doing simple science experiments.

This experiment aims at exploring air pressure – children will be baffled and work hard to come up with a theory.


  • A clear plastic squeeze bottle
  • Eyedropper
  • Water
  • Coloured water


  • Fill the plastic bottle with clear water
  • Float the eyedropper vertically in the coloured water by sucking water in the dropper until it floats upright (it is best to test this in a tall glass)
  • Place the dropper in the bottle and put the top on tightly
  • Allow the children to experiment with the bottle – squeezing it and observing what happens to the dropper and the water inside it
  • What happens if the top is open?
  • Note: Never tell the children the answer if you know it. They will get more pleasure and develop their problem solving skills better if they are allowed to explore rather than be told.
