  1. 1. Science Project <br />By : KohTzeHeng Roy(Leader)<br />Koh Zhao Hui<br />Lim Jin Yuan <br />Yap Wang Qing<br />
  2. 2. Pepper and Soap <br />To do this fun pepper and soap experiment, you will need: - a clear dish- water- pepper- dish soap<br />
  3. 3. Pepper and Soap<br />1st: Prepare a dish with clear water<br />2nd: Sprinkle the pepper inside the water<br />3rd: Dip your index finger with soap for 2 second and take it out<br />4th: Dip your hand inside the clear water<br />5th: Observe the clear water “Running Away”.<br />
  4. 4. Pepper and Soap<br />HEY WHAT HAPPENED???<br />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.”<br />
