ThinkGeek has created a set of coasters that reveals the anatomy of your brain.
The glass coasters comes in sets of 10 pieces, with each one printed with a slice of brain specimen, and is labeled so that you can stack them up in the proper order when they are not in use.
The image of a whole brain can be seen when you look at it from a right angle—these would definitely be a hit with your science-loving friends.
Head over here to purchase the coasters.
