- small scraps of paper
Rub a plastic pen on the wool sweater and hold it near small pieces of paper. Watch the small pieces of paper stick attach to the pen.
When you rub the plastic pen to the wool electrons move from the sweater to the pen. Next positive charge of the paper is attracted to the negative charge of the pen thus the small pieces of paper attach to it.
