This Maze Mug Seems Like a Great Way To Kill Time/Spill Your Drink

If you've already tired of the hundreds of games on your smartphone, here's another way to kill time on your long morning commute—and possibly even finally beat your caffeine addiction. This double-walled insulated mug features a series of mazes on the outside that has you skillfully piloting a ball bearing through the various corners and dead-ends.

And in the process, you'll probably end up spilling the majority of your coffee. Keep at it for a week, and you'll not only have mastered those mazes, you'll probably also be less dependent on a kick of caffeine in the morning. And for $25 who could ask for more? [Amazon via 7Gadgets]
