It's easier to dedicate yourself to solving a complex maze when in the back of your mind you know that should frustrations arise, you'll be able to simply hurl it across the room for some instant stress relief. Shouldn't all puzzles be as relaxing?
Available in three different skill levels including easy, medium, and hard, these spherical mazes, about the size of a softball, are a better way to relieve stress as they help keep your brain sharp at the same time. And at just $US10 ($14) each, if one happens to end up smashed to pieces on the floor for unexplained reasons, replacing it isn't going to break the bank. [ThinkGeek]
