    • Pepper and Soap
      To do this fun pepper and soap experiment, you will need: - a clear dish- water- pepper- dish soap
    • Pepper and Soap
      1st: Prepare a dish with clear water
      2nd: Sprinkle the pepper inside the water
      3rd: Dip your index finger with soap for 2 second and take it out
      4th: Dip your hand inside the clear water
      5th: Observe the clear water “Running Away”.
    • 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.”
