First you need to gather up all of the materials you will need. Below is a list of the following items needed to conduct this experiment:
• 1 plastic comb
• A sink
• A water faucet
Are you ready? Let’s get started. First, you need to turn on the faucet so that the water runs out in a small, steady stream. The water stream should be no more than 1/8 inch thick. Next you’ll want to give the plastic comb and electrical charge. You can do this by running it through your hair (as long as your hair is dry) a few times or you can rub it quickly and repeatedly against a sweater. Finally take the comb and slowly bring it towards the water. What happened? Did you see the water bend?
So why did the water bend? Basically, the water is neutral and doesn’t have any electric charge. Because the comb is near the water and it is electrically charged, the water then becomes attracted to it and moves towards the comb. Cool, huh?
Here is another idea that you could do to change up the project a little bit and see what happens. You could try using a balloon instead of a comb. Make sure you charge the balloon the same way you charged the comb.
