• A Balloon
• Strong Lungs
• A Woollen or Nylon Sweater (Jumper)
A sticky experiment!
Steps:
1. Blow up the balloon and tie the end so that
the air does not escape.
2. Take the balloon and rub it vigorously
against your jumper/sweater or your head of hairs about ten times.
3. Now hold the balloon against your jumper/sweater or hairs
for a minute.
4. Let go of the balloon. What happens? Does
it stick?
When a balloon and a jumper/sweater or hairs are rubbed
together; each will gain a different type of electrical charge. The
balloon becomes a negative charge and the jumper/sweater or hairs
becomes a positive charge.
Opposite charges attract each other.
