Does the color of hair affect how much static electricity it will hold? If brunettes hold the most amount of static electricity, then the red haired subjects will hold the least amount of static electricity. For this project, two of each color hair will be rubbed with a lightly colored-balloon for thirty seconds. Then the balloon will quickly be put on the wall and timed for how long it takes to fall down. Then it will be recorded and the results will need to be analyzed. The brunettes still held the most, but the blonds held less static electricity that the red haired people. The hypothesis was rejected in this experiment.

Everyone loves to stick balloons to the wall with static electricity. Balloons are made of natural latex. Static electricity is a build-up of electricity in one area or on an object. There are three main parts in electricity protons, electrons and neutrons. When testing static electricity in hair with balloons, it is important to understand static electricity, hair pigments, and balloons.

Most balloons are made from natural latex, which is made from rubber trees. The natural latex is highly regarded and biodegradable. Synthetic latex, which is not biodegradable is also used in some circumstances but is more cost effective. The sound of balloons popping is actually not from pressure, but from the tightly stretched pieces of latex snapping back at the speed of sound. The sound is resembles a sonic boom, like a jet produces.

Static electricity is a build-up of electricity in one place. Atoms are composed of three parts; positively charged protons, negatively charged electrons and neutrons, which have no charge. A positive and negative charge on one object is called static electricity. When electrons are transferred from one object to another object, the object becomes charged due to the friction. When an object loses it’s charge it becomes neutral.

There are two kinds pigments for hair. Eumelanin is a dark pigment found in black and brunette hair colors. Phoemelanin is a light pigment found in red hair. Small amounts of brown eumelanin can produce a blond hair color. People with dark hair may still produce a yellow-orange hair color; it is largely masked by the dark eumelanin pigment and cannot be seen very easily.

When testing static electricity it is important to understand static electricity, hair pigments, and balloon . There are two different types of hair pigments emeulanin and pheomelanin. Static electricity is composed of three parts . Balloons are made from rubber trees. If brunettes hold more static electricity, then the red haired subjects will hold the least amount of static electricity.

8 lightly colored balloons

2 red haired subjects

2 brunette subjects

2 blonde haired subjects

Pencil

Timer

Choose at least two people of each hair color to be subjects

Blow up the eight balloons all the same size

Start by having him/her rub the balloon on their head for thirty seconds

Then stick the balloon to the wall

Time how long the balloon sticks to the wall

Repeat with every person three times

Analyze the results and formulate the conclusion

The results of the experiment were not as expected. The time it took for some of the balloons to fall was very long. The longest time was subject number two, she had a...
