Glowing Arc Reactor Coasters Are Just Enabling Tony StarkS

It wasn't dealt with much in the movies, but in the Iron Man comic books Tony Stark is constantly battling alcoholism. And that's what makes these light-up glowing coasters ironic. On the big screen, he used the technology he developed to fight crime and make the world a better place. But in the comics, he would have probably been more inclined to turn the arc reactor into drink coasters just like these.

Available exclusively from ThinkGeek in a set of four for $30, each aluminum coaster is powered by a pair of watch-sized CR2032 batteries. The embedded LEDs make any drink placed on the coasters glow a eery blue tint, and to maximize the life of those tiny batteries the LEDs automatically shut off after five minutes. The life of a superhero isn't easy, but who says it has to be dry? [ThinkGeek]
