There's one thing that's pretty cool, no matter who you are. Science experiments.
Not the boring calculations, and theories, and all that stuff. But the actual experiments that people do to prove all those crazy ideas the scientists have are true. Whether it's a simple thing, or an insanely difficult thing to do, it's always pretty cool to watch.
Large Hadron Collider? WTF? But show me the stuff exploding when you collide stuff...I'm there.
Things falling slowly in a vacuum? Hell yeah!
