An Australian company has developed a neat little tool called the BottleMate that easily pops the caps off of bottles while preserving their circular shape. Normally, if you have to open a bottle with a sealed cap, you end up bending it somehow with a bottle opener which really messes up the shape of the cap itself.

In any case, this is a pretty neat product I think and something that might make me start a personal collection of bottle caps just for fun. Thanks Dan for the heads up on this!
