Messing with my suite mate

So on Sunday Night after the Giant's somehow won against the 49'ers. I thought it was a fluke. :) But anyways I decided to have fun with my friend next door, while he was sleeping I borrowed a few of his things. I took his magnets, bottle caps, and his old lighter. I decided to use magnets and the bottle caps together to make a weird/abstract sculpture and stick it to the lighter. I wish I took a picture, but that's what I'm not going to talk about. It was the magnetism that made me think. How can something just come together like that? I have a little knowledge about magnets from grade school, but there was something about how they react to each other. It's a mystery to me even though is proven by science.

It got me thinking about out talk yesterday with gravity. Its something that people try to describe but you can't really describe it. I'm a little confused any thoughts?
