Gyroscope Twin Pack

A vintage throwback with some very current fun potential, this double gyroscope kit brings back the cool science contraption that's been on the market since 1917. Used to illustrate various physical properties, such as momentum, inertia, and torque, gyroscopes seem to defy gravity as they spin and perch in a series of amazing tricks, such as balancing on the rim of a water glass. Great for exploring physics concepts, or just playing around, gyroscopes are spinny retro fun! (Tedco, $9.75)
