Charging by Induction

Today we did a silly activity to show charging by induction. Everyone was a proton or an electron in a conductor connected to the ground. I scared some of the electrons away into the ground with a negatively charged balloon to leave the conductor with a positive net charge. Then I attracted some electrons out of the ground into the conductor with positively charged candy, leaving the conductor with a negative net charge.

Homework tonight is Electrostatics III.
