Update: my hand hurts now, but in fact it is possible to lay down a pinky, then snap three times successively with ring, middle, then index, which makes three different snaps (descending in pitch).
I gotta say, surprised everyone is attributing the “snap” sound to hitting the pad of your thumb.
All y’all veteran snappers, try this. Lift up your pinky, then snap. Makes a much higher pitched snap. Now lift up your ring finger, then snap. No snap at all. Your pinky and ring finger make a sort of tube, and your thumb is striking one end of it (the crevice between thumb pad and ring finger tip) to make a tone. I’m even able to smack that spot with a finger on the OTHER hand and make a (quieter) snap.
Hope this helps.
Probably some manufacturing artifact. Maybe the machine needs somewhere to grip the tubibg as the micro hole punchinator 6500 does its thing
Cool! What part did you learn??
