Electricity Experiments: Balloon Static
 
Stuck on You
Materials you will need:

• A balloon
• Strong lungs
• A woollen or nylon sweater (jumper)

A clinging 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
