Static Electricity (Balloon and Woolen Cloth)

Experiments | 7-12 yrs | Video

REQUIREMENTS

  • Balloon
  • Shreds of paper
  • Pure woolen fabric

HOW TO DO

  • Rub the balloon hard and quickly on the woolen cloth. Do this a few times. Why do you think this is required?
  • Bring the balloon close to the paper shreds.
  • You will see that some paper shreds rise and stick to the balloon’s bottom. In case they didn’t, maybe you didn’t rub the balloon hard enough. Or perhaps, the woolen cloth was not pure. Make changes and try again.

WHY THIS HAPPENS

Rubbing the balloon against the woolen fabric creates static electricity. This involves negatively charged particles (electrons) jumping to positively charged objects.

When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.

TRY THIS

Do this static electricity experiment with a balloon and woolen cloth. You will find out what happens. It will seem like magic!
