I have a science experiment about static electricity. I have a sheet of copper which is attached to an alligator clip. This is then supposed to be attached to a ground connection. Can that be anything metal like a screw? Does it have to be something very large and metal?I‘m discharging the static electricity from a balloon and pieces of paper using the copper. It seems that when I used just a screw, the balloon still had quite a bit of static electricity. When I used a large metal object, it did not.
