`Oh, snap!’ A record-breaking motion at our fingertips

Researchers studied the physics of a finger snap and determined how friction plays a critical role. Using an intermediate amount of friction, not too high and not too low, a snap of the finger produces the highest rotational accelerations observed in humans, even faster than the arm of a professional baseball pitcher.
