think about Benjamin Franklin twenty-five years before Declaration of Independence naming the first "battery" (out of the concept of lined-up artillery) by connecting a series of lynden jars (basically capacitors) - he also invented the concept of +/- positive and negative
now we've got space telescopes and probes leaving the solar system
imagine what's coming in another 300 years

That's an amazing fun fact.

Another fun fact is that it was impossible to deduce from any of Ben Franklin's experiments what material was transferred and what material remained in place to give rise to "charge" as we think of it. So he picked a convention that we've continued to use even after we learned that his negative charges were the material that gets transferred by friction.

somewhat more "fun" and impressive (despite useless) are "Franklin Bells" which way before anyone figured out electric motors, was the first example of electricity to mechanical energy
but it must be said, as genius as Franklin was, sadly he bears the original sin of owning slaves EVEN AS AN ABOLITIONIST and didn't free them until after his death (via will) - it's more than a little f-ed up

Franklin also invented the lightning rod, something which we take for granted these days.

of course incredibly crude
