Transparent jar

Rubber balloon or a piece of stretchable rubber sheet


Few chick peas or black gram or dry green peas


  • Put the seeds in the jar
  • Sew the string to the centre of the rubber sheet and put some tape to keep it tied securely.
  • Stretch and tie the rubber sheet on the mouth of the jar
  • Now run your fingers up and down the string by first tugging at it slowly and then rapidly.

Pull the string first slowly, then vigorously to show movement of particles as in solids, liquids and gases.
