Ellie Electricity's Wild Hair

Objectives

To observe how a charged balloon can make hair repel and show that an object with static electric charge acts like a magnet

 

Materials

• Balloon

• Tissue paper

• Hair (long, fine hair works best)

Procedure

Inflate the balloon. Charge the balloon by rubbing it against the hair. See what happens.Then tear the tissue paper into small pieces. Lay them on the table. Hold the balloon over the paper. Observe what happens.

Conclusion

Electrons move from the hair to the charged balloon. Now, each of the hairs has the same positive charge. Items with the same charge try to move away from each other. In this case, the hairs all try to stand up and move as far apart as possible. After rubbing the hair, the tissue paper "jumps" onto the charged balloon.
