heres a idea

What you will need:

A comb

Thread

Small pieces of dry cereal (O-shaped or puffed rice of wheat)

What to do:

1.) Measure a twelve-inch piece of thread and secure one piece of cereal to the end. Attach the other end of the thread to something such as a table but make sure that the cereal does not hang close to anything else.

2.) Remove oils, dirt, and hair strands from the comb by washing it. Make sure that it is entirely dry before you use it.

3.) Fill the comb with static electricity by rubbing it on a sweater or by combing long, dry hair with it a few times.

4.) Lift the comb near the cereal. The cereal will move towards the comb. Hold the comb where it is until the cereal moves away on its own.

5.) Bring the comb near the cereal again. This time, the cereal will move away from the comb.

6.) A balloon can also be used in place of the comb.

What happens: Electrons are moved from hair or a sweater to the comb. Because the comb was charged with a negative static charge the comb, which was neutral, was attracted to it. When they meet, the electrons are taken away from the comb and put into the cereal. Because both items had the same static charge, the cereal was not attracted to it and moved away
