Mine is kind of weird so here ya go.
My Astronomy teacher was once talking about some guy (I think it was Plato) arguing with another philosopher type guy about why a rock would fall faster to the ground than a feather. One guy said the feather has more a divine essence so that is why, it wants to go to heaven, and the rock is evil or whatever. Blah Blah all the other guy had to do was crumple up the feather and drop it and it would fall faster obviously blah blah. The point was that we would of discovered pretty much gravity almost 500 years before the guy with the apple and such. So then he said think of what we would have 500 years from now, space travel and such, we would have today if all he did was crumple the feather.
All in all I'd have the guy crumple the feather.
I don't know details about this but I'm pretty sure it happened or something, I mean after all it was in a book.
