An electroscope is used to detect the presence of electric charges, to determine whether these charges are positive or negative, and to measure and indicate their intensity. By the help of this electroscope we will see the movement of electrons.Things Required:Aluminium foil, as thin as possibleGlass jar, 1 qt. (1 litre)Soft plastic lid to cover

“Never use an electric appliance while you are in the bathtub!”Although it is not a great conductor of electricity, water can easily conduct the current that flows from the power outlet of your home.
