I followed the directions in a book to make a simple electroscope out of electrical wire and aluminum foil in a jar. I passed the wire through a cork and into a jar and hung a thin strip of foil on the wire. The other end of the wire poked out of the cork, and I put a tight ball of foil around it. If I put a charged object near the foil ball, the leaves of foil inside the jar are supposed to flare apart. But they don't. I can hear some crackling around the foil ball, but nothing happens inside the jar. What am I doing wrong?
