Surface Tension Experiment

Speedboat Matchsticks

Materials you will need: • Water • A Bowl • Liquid Dish Soap • Wooden Matchsticks

Steps:

1.  Fill a bowl with water and place a few matchsticks on the water.
2.  Drop in a small amount of dish soap into the centre of the bowl and watch the matches shoot across the surface of the water like power boats.

It works because the soap gives off an oily film that rushes outwards, breaking down the surface tension of the water and pushing the matches away.
