North Paw Directional Anklet Kit (video)
Always know where magnetic north is and get an awesome science experiment in one package with the Paw Directional Anklet Kit that you assemble yourself and then use to continue your experiment. Once you assemble the anklet with all the enclosed parts, you get to test it out on your ankle. It has a compass module that powers eight pager vibrating motors that surrounds your leg.
Wearing the anklet is supposed to train your brain to know where magnetic north is, but then, your brain starts to tune out the vibration and you just know where the direction is. Studies suggest that after using it for a long time, once a person stops, they’ll experience a weird sense of direction. It’s a great little gizmo for those who like to experiment with science or outdoor enthusiasts who don’t ever want to get lost. The kit costs $159.99.
