The Jumping Rice

The procedure: rub in the plastic spoon to the piece of woollen material then keep it above the plate with the dry rice. The grains of the rice will jump up and get stick to the bottom of the plastic spoon and fall back to the plate in the different directions.
The result: During this procedure the part of the electrons of the spoon went to the grains of rice which got stick to the spoon and the got the same electrostatic charge as the spoon’s charge. The grains of rice fell down and started jumping because of the same amount of the charge, which pushes each other to the different directions
