Electroscope project

In class we learned about eltroscopes. We learned that the electrons from the ballon transfer to the tinfoil and makes it move. So for our project we needed a paper clip, ballon, cardboard circle, tinfoil, tape, and a clear cup. We put the cardboard over the cup and make hole in it to put the straightened paper clip in. On the paper clip we had two tiny pieces of tinfoil. After that I rubbed a blown up ballon onto a sweater and put it close to the top of the paper clip. After I did that the two pieces of tinfoil moved away from each other. They did this because of the electrons.
