Next time you need to fill up some time on a rainy day, pull this out of your bag of tricks . . . .
Use a child. Tip their head back and ask them to balance an Oreo on their forehead. I know, it sounds weird. Buckle your seatbelt. It's gonna get crazier. The goal is to move the Oreo into their mouth without using their hands. Only flexing face muscles and using funny faces to move the cookie . . . .
Have a contest. Have a camera ready!
