How to make a homemade electroscope
The homemade elctroscope consist of a vertcal copper metal rod, which has a kind of sphere on the top and at the opposite end two sheetd or flakes of aluminum foil. When an electrified object is brought closer to the sphere, the rod is electrified and the electrically charged aluminum lamellae repel, separating.
For this experiment, the following materials are needed: a glass jar with metal lid, aluminum foil, a piece of copper wire, scissors, silicone for gluing and a balloon. Procedure: First you make a small hole in the lid, so that the wire can pass. After introducing it there, you make a hook in the lower part, and in the upper one, a spiral. Then, cut two pieces of aluminum foil, about 4 by 2 cm, not too large. Then, make a small hole in the top of each piece. That will allow you to hang them on the hook. And finally, put the lid on the jar, and go! When approaching loaded bodies, the leaflets will separate.
