            PEPPER  EXPERIMENT
                 SURFACE TENSION

Introduction :
   
      This is a simple and easy experiment which can be done by kids.. This explains the concept of surface tension. The materials which we need in this experiment, we can get from our house..

Materials Needed:

Tray

   

Pepper powder

Dish washing liquid

Procedure:

Step-1:

Pour some water into the tray.


Step-2:

Sprinkle some pepper powder in water. Apply some dish washing liquid on your finger.
