Does hair color change how much static electricity builds up? You rub an inflated balloon against four natural-hair wigs: black, brown, blond, and red. After six rubs in one direction, you hold the balloon over tiny paper squares.
You count how many paper pieces stick to the balloon. Each wig is tested five times. All four hair colors pick up nearly the same number of paper pieces.
Hypothesis
The hypothesis is that the color of hair does not affect the amount of static electricity it will produce.
Rubbing different materials together builds up charge, but the amount may depend on the material's traits. You rub a balloon against natural-hair wigs of four different colors and then hold the balloon over small paper squares. Each color picks up nearly the same number of paper pieces, showing that hair color does not change how much charge builds up.
Electric charge causes objects to push or pull on other things nearby. After rubbing a balloon against natural-hair wigs, the balloon pulls tiny paper squares toward its surface. All four hair colors produce a similar effect, showing that charge transfers through rubbing regardless of hair color.
The triboelectric effect depends on the materials involved, not on how they look. Rubbing a balloon against wigs of different hair colors — black, brown, blond, and red — tests whether color changes how much charge builds up. All four hair colors pick up nearly the same number of paper pieces, showing that charge transfer comes from the material itself, not its pigment.
Method & Materials
You will use a balloon, copper plate, ground connection, jumper wire, and four natural hair wigs of different colors. You will rub the balloon on the wigs and measure the amount of static electricity produced.
You will need a balloon, copper plate, ground connection, jumper wire, four natural hair wigs of different colors, a flat tray, ruler, piece of letter size paper, and a pen knife.

The results showed that the black, brown, blond, and red hair wigs produced almost the same amount of electrostatic charges. This proves that the color of hair does not influence the amount of static electricity produced.
Why do this project?
This science project is interesting because it shows that the color of hair does not affect the amount of static electricity it produces, even though the physical properties of the hair can.
Also Consider
Consider repeating the experiment using a comb instead of a balloon, or try different types of hair like curly, wavy, and straight. What if the hair is wet? Do you think the amount of static electricity produced will be greater or less?
