Surface Tension Experiments – Some simple but amazing tricks

The first thing that comes in our mind is, “what is surface tension?” Surface tension is a natural phenomenon which describes a force with which the molecules of a liquid attract each other. There are several surface tension experiments which are fun, simple and safe to follow.

Popular Surface Tension Experiments:

Some of the popular surface tension experiments which are quite amazing and useful in explaining surface tension are:

  1. Take a glass and fill it with water until it forms a convex shape on top of it. Now take ten to twelve quarters and one by one put them in this glass. But remember to be slow and careful while doing so and the quarters should be placed with their narrow edge in center of the glass before you let them go. It’s really astonishing to see that the water on the surface becomes more convex without overflowing.
  2. Another interesting experiment is to take a tissue paper strip, needle and a glass filled with water. Now allow the tissue paper strip to float on the surface of water and gently place the needle on this tissue paper. Soon you will see that the strip will sink in the water but the needle will stay on the surface. This is a simple experiment to display surface tension which makes heavier object to float on water.
  3. This is a really cool surface tension experiment. All you need is a piece of paper, tiny bit of soap and a basin filled with water. Cut this paper in a shape of a boat and make a hole in its center. Now make a narrow opening which goes from the back of the boat to the hole in the center. Place this paper boat on the basin filled with water and put tiny bit of soap in the hole of the boat. This will make the boat to quickly propel forward.

Conclusion:

This article sheds light on surface tension experiments which are simple to follow and fun to try at home.
