Water Surface Tension 1

Experiment No. 10

Experiment: To show that water has a skin

Materials:

You will need:

Paper Clip
Water
Basin
Blotting Paper

Method:

1) Half fill the basin with water

2) Try and float the paper clip on the water - it's very difficult!

3) Try placing the paper clip on a piece of tissue or blotting paper. Allow the tissue or blotting paper to sink and see what happens.

Result: The paper clip floated on the surface - though we had to be very careful, or it sank.

Conclusion: Together with lots of other liquids, water has a thin skin.
