Electroscope - A simple indicator device for determining the electric charge. It is very simple to do at home with your own hands. To do this, we need a piece of foil and a jar with a plastic lid.
For better stability, a cocktail straw and a plastic ball are wrapped inside the foil.
Please note that for weightiness at the ends of diverging plates there are small twists, they can adjust the sensitivity of our electroscope.
