Bending Water Category: Science
Dated: 2010-06-12
 
You can bend a water stream with a comb without touching it!

Steps to be taken

   1. Comb dry hair with a nylon comb or rub it with an inflated latex balloon.
   2. Turn on the tap so that a narrow stream of water is flowing.
   3. Move the balloon or teeth of the comb close to the water (not in it). As you approach the water, the stream will begin to bend toward your comb.

How It Happens

When two objects are rubbed against each other, some of the electrons from one object jump to the other. The object that gains electrons becomes more negatively charged; the one that loses electrons becomes more positively charged. The opposite charges attract each other in a way that you can actually see. One way to collect charge is to comb your hair with a nylon comb or rub it with a balloon. The comb or balloon will become attracted to your hair, while the strands of your hair (all the same charge) repel each other. The comb or balloon will also attract a stream of water, which carries an electrical charge.
