Sometimes electric charges build up on the surface of a body when it is rubbed against another one. The rubbing action causes electrons in one body to move from one place to another. This moving and interchanging of electrons leaves a surplus amount of positive charge on one body and an equal amount of negative charge on the other. Hence, when these materials are separated, the charge imbalance is retained and upon coming in contact with another body of opposite charge, a limited electric shock is felt. This shock may not be of the same magnitude as that from conventional electricity, but it is strong enough shake you up momentarily. The static electricity can be produced in a very simple way with the help of an experiment. This experiment can prove to be a good idea for students in search of ideas for Science project. Lets us perform the experiment by following the below given steps.
Walking on Carpet
After putting the shoes on, step on a carpet. If you do not have a carpet available, simply stand on a piece of carpet.
Developing static charges
Rub your feet on it and keep doing it for a few minutes to develop static charges in your body.
The shock felt
When you touch the other person or metal object, you will receive a shock strong enough to make you jump. This is because of the static electricity that is created - as explained earlier in the introduction.
