Static Electricity Experiment

Static Electricity Experiment

This experiment regarding static electricity tries to educate and entertain student by making use of some very simple objects. As we all know opposite charge attracts whereas similar charges repel each other. This experiment will put that property to test. So let’s not beat around the bush and start what we came here for!

Things you will need:

  • Wool
  • Can – Aluminum
  • Your hair
  • Balloons with their strings intact – Two

How to do it:

  • Firstly take the balloons and rub them against the wool one by one. After doing that bring them closer to each other. Are they attracted to each other or repel each other?
  • Secondly take one of the balloons and rub it on your hair repeatedly and then carefully take it away.
  • Take the aluminum can and put it down horizontally on a flat surface. Rub the balloon on your head and place it next to the can. The can will follow the balloon around wherever you drag it.

What happens?

When you take a balloon and rub it against your head or a ball of wool it leads to the creation of static electricity. This is caused due to electrons moving from one place to other due to attraction towards the positive protons. The balloon when rubbed on a head full of hair takes negative particles from the hair and leaves them as positively charged.
