Equipment:
Pepper
Plastic box
Wool scarf
Method:
Dust a thin layer of pepper into a small transparent plastic box.
Put the lid on and then rub the lid with the wool scarf for 30 seconds
Now, watch the lid. You should begin to see specks of pepper jumping up and sticking to the lid of the box.
How come?
The motion of rubbing the lid with the wool scarf causes static electricity to build up thus attracting the pepper!
