Finger snapping

Common card · No. 272589

Snapping (or clicking) is the act of creating a snapping or clicking sound with one's fingers. Primarily, this is done by building tension between the thumb and another (middle, index, or ring) finger and then moving the other finger forcefully downward, so it hits the palm of the same hand at a high speed. A Georgia Institute of Technology study in 2021 analyzed finger snapping, and found that a given audible snap sound occurs in just seven milliseconds. For reference, the blink of an eye takes place in 150 milliseconds.
