In the picture below you should notice a curved line about an inch up from the bottom of the glass. It's a small ridge on the inside of the glass and it's purpose is so cool. Stack another glass on top of this one and that ridge prevents the second glass from going all the way down. That prevents the glasses from becoming stuck together and eliminates injuries from breaking glass when trying to pry them apart and the cost to replace them. Simple, but ingenious solution!
