Waterfalls

My guess it's the same reason people are impressed with mountains or oceans. I don't know about you, but the sound of the ocean rocks me to sleep better than anything. And mountains are really, like, big. Yeah, they are just natural phenomena, but that doesn't make them less impressive.

What about rainbows? And shooting stars? All stars for that matter. Maybe it's just that some things make you feel small, so you're impressed.
