Got a plastic comb? Then you can make magic. Turn the faucet handle until a very thin, steady stream of water comes out. Run the comb through your hair several times. Slowly bring the comb with teeth facing toward the water. Amazingly, the water will bend toward the comb.
Thank your lucky atoms for this one! Atoms are the microscopic building blocks of our world. They're made up of protons (with a positive charge), electrons (negative charge), and neutrons (no charge). Static electricity is caused by electrons moving from one object to another when they are rubbed together--such as scooting your socks across the carpet.
When you comb your hair, the object that loses electrons (your hair) becomes more positively charged, and the object that gains electrons (the comb) becomes more negatively charged. A charged object begins to attract molecules around it. As the charged comb attracts the molecules of water, which can be moved easily, the stream bends toward the comb. You may also notice that the strands of your hair start to stand up slightly. This is because the strands are more positively charged and start to push each other away.
