A Snack Safe That Only Unlocks After You Walk Far Enough
The Snack Safe is a lockable container for treats that won't open until you've walked a set distance. To get to the food inside, you first have to earn access by walking.
Matty Benedetto of Unnecessary Inventions built the device around a pedometer-controlled locking mechanism and introduced it on his invention website.

Before you can have a snack, the snack box demands a walk. You might work up an even bigger appetite just trying to open it.
