Pepper and Soap To do this fun pepper and soap experiment, you will need: - a clear dish- water- pepper- dish soap

Pepper and Soap HEY WHAT HAPPENED??? Surface tension on water makes a strong 'skin' which is tight and not very elastic. The pepper stays on the water until soap or detergent touches the skin. Soap and detergent reduce the attractive forces between water molecules--that is, they reduce surface tension. The skin stretches, scattering the pepper.”
