Answer:

            Here's how to make a telephone  

Material needed is as follows - 1. Two paper clips 2. Two paper cups 3. About 3 yards (2.7 meters) of string 4. Pin Here's what to do -: Make a hole in the center of the base of both cups, using the pin. Tie one paperclip to one end of the string. Pull the other end of the string through the hole in one of the paper cups. The paperclip should be inside the paper cup. Insert the free end of the string into the hole in the bottom of the second paper cup. Insert it from the outside of the cup. Pull enough string through the hole to enable you to tie the second paperclip to the end of the string. Pull the cups apart so that in each cup the paperclip rests flat on the floor of the cup and the string is taut. take one cup, and have a friend take the second cup. Walk away from each other until the string is taught you're now ready to use your paper cup phone.

How to make your own Electroscope:

You can build your own electroscope at home using simple things you can find around the house, such as:

a glass jar,

2 little pieces of aluminium foil cut into small round shapes (and you need to put a whole in one end of each foil);

A copper wire (spiral one of the ends of the wire to make a large surface area);

Some electrical tape,

A plastic lid cut into a circle the same size as the jar opening (you can use the plastic lid from any plastic container);

A small plastic tube (you can use a straw) shoved through the plastic lid.
