Rub a comb quickly against the piece of wool, nylon or fur for about a minute
Hold the comb near a trickle of water from a faucet.
The charged comb should attract the water toward it.
Why does this happen? By rubbing the comb, you're covering it with little negative charges. The negative charges are attracted to the positive charges against the water.
