Stick your thumb in a coke bottle and "pop" it out.
Clap you hands when flat and then when cupped (much louder).
The majority of the sound is from the rapid change in air compression.
In the case of the fingers, the air pocket made by the lower 2 fingers when rapidly struck by the releasing middle finger.
Others can "snap" their fingers by actually using the thumb with other fingers in a fist (like the coke bottle above)
Another example is the "pop" made by rapidly pulling your tongue from the roof of your mouth.
The homophone for a metal fastener is "bolt" and for a sound made with fingers is "snap."
That is a snap.
Pressure and friction
O-o snap
Snap.
A "snap" or "click". Snapping your fingers, or Clicking your fingers.
snap your fingers
By snap I assume you mean snapping your fingers, if that's the case, the answer is no, the sound generated from your fingers are caused by friction and when you fail to make a sound it just indicate that there is insufficient friction, thus it is just a technique that not perfected!

There are no health advantages when you snap your fingers. But its also not dangerous at all. Snapping your fingers breaks the vacuum seal created by the synovial fluid and the breaking of that seal causes the popping sound. There are no health advantages by doing this.
