I thought this was an interesting tidbit, so I thought I'd share:
On this day in history, in 1752, Benjamin Franklin conducted an experiment to prove that lightning is electricity by flying a kite in a thunderstorm. Earlier, in 1750, he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin's experiment (using a 40-foot-tall iron rod instead of a kite) and extracted electrical sparks from a cloud. On June 15, Franklin conducted his famous kite experiment and also successfully extracted sparks from a cloud (unaware that Dalibard had already done so, 36 days earlier).**

That’s all. Class dismissed. No running in the hallways.
