Water Surface Tension Experiments

Below is a video showing a water surface tension experiment. There are many surface tension experiments of water or other liquid surface tension experiments. Below is a simple water surface tension experiment that you can do at home using just a glass of water and a paperclip.

What is surface tension?

Surface tension is the force required to break a film of length 1 centimeter. Surface tension is measured in dynes per centimeter.

What is the surface tension of water?

Water has different surface tensions at different temperatures. At 20 degrees, water has the surface tension of 72.8 dynes/cm. The surface tension decreases as the temperature of water increases.
