How to do pepper and water surface tension science experiment by teaching kids about surface tension.

The reason the pepper sits on the water is because of the high water surface tension. The water molecules are strongly attacked together.

Pepper is hydrophobic, meaning that water is not attracted to it. Because of that, the pepper does not dissolve in the water and it floats.

Why does the pepper shoot to the sides when dish soap touches the water?

Science behind this experiment
Soap is able to break down the surface tension of water - that’s part of what makes soap a good cleaner. As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap, and carry the pepper along with them.
