How fast can a human move their finger?

With naked fingers, a snap accelerates in 7 milliseconds. Its rotational velocity, which is an object's rotation rate, is an astounding 7,800 degrees per second — three times as fast as a pro baseball player's arm. Turning down the friction by lubricating fingertips resulted in a slowdown.
