Inventor Mikal Hart shifts geocaching in reverse.  Hart’s “Reverse Geocaching Puzzle Box” is a locked box that needs you to deliver it to a secret location.  The box won’t unlock until you take it to this pre-programmed destination.

The GPS-enabled box presents users with a deceivingly simple button and a small display.  You press the button and the display reads a distance. Players only have 50 chances to move the box to the correct location before the box locks forever.

There are many more geocaching adventures. Take a look at all the Lost & Found videos here.
