Make a kite 1.build the frame by making a small cross 2.tie the corners to the points of the cross 3.add a tail to the frame 4.tie a long string to the cross 5.fix a sharp piece of metal to the top of the longer stick 6.fasten a key to the end of the long string 7.tie a silk ribbon to the string above the key Metal: pull the electricity from the cloud Tail: keep the balance of the kite Key : conduct the electricity into the condenser Ribbon: made it safe to hold the string

Shed Franklin and his son stand inside a door or some cover, fly the kite when a thunderstorm appears to be coming on. When a thunderstorm comes over the kite, the sharp piece of medal will pull the electricity from the cloud. The kite and the string will become charged.
