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 skilfully 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 $US25 who could ask for more? [Amazon via 7Gadgets]
