Ben Franklin discovered electricity while flying a kite.
There are several flaws in this story, one being that Ben's discovery occurred when he was flying a kite with a key tied. The American founding father was already interested in electricity before even conducting the famous experiment that many others tried first. Some historians are sceptical as to if the kite thing even happened at all based on his vague reports. But regardless, Ben's hypothesis sparked curiosity (no pun intended) and encouraged others to confirm it themselves.
