Getting a walnut out of its shell is probably one of the biggest challenges you're ever going to face. Getting to that sweet snack is an immensely difficult task, which means you are going to need an immensely effective tool. I think I may have something here that will cure your nut-cracking woes: the Walnut YoYo. Simply place the coveted treat inside the orb and then smash it against a hard wall to release it from its prison.
Designed by Xiaofei Wang and Beibei Wu, the Walnut YoYo puts a clever spin on a task that is otherwise frustrating and mundane. Just don't get too carried away with it at family functions--no one appreciates getting knocked in the head with a walnut.
