简述：
Almost everyone has heard of Franklin's famous experiment,but few of us actually understand how the experiment worked.On a stormy day,Benjamin Franklin went outside with a kite in his hand.When a storm cloud passed over Franklin's kite the negative charges in the cloud leaked onto his kite,his kite string,his key,and a Leyden jar attached to the key by a thin metal wire.Franklin however,was unaffected by the negative charges because he was holding a dry silk string which insulated him from the charges on the key.When Franklin reached out his knuckle to touch the key he received a shock,because the negative charges in the key were so strongly attracted to the positive charges in his body that a spark jumped from the key to his hand.Franklin's experiment successfully showed that lightning was actually static electricity.
