a FACT U should know #5

Ang tunog na naririnig kapag pinapitik (snap) mo ang middle finger at hinlalaki ay hindi nanggaling sa friction ng dalawang daliri kundi galing sa paghampas ng middle finger sa ilalim ng hinlalaki.

The sound produced when snapping the middle finger and the thumb is not from the friction of the two fingers but from the striking of the middle finger to the thumb's lower part.
