Hair color and static
The hypothesis that hair color will not affect the amount of static electricity produced is proven to be correct.
Natural hair is made from keratin which is the same type of protein that is also found on nails and skin. The static charges in our hair are carried by keratin. The proteins that determine the color of hair do not affect the ability of the keratin to carry static. Therefore, the color of hair does not influence the amount of static electricity produced by the hair. However, the physical properties of the hair, such as its thickness, can affect the amount of static charge produced on.
The experiment can also be done using a comb instead of a balloon.
Try to repeat the experiment using 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?
