I couldn't even get past the first paragraph of this nonsense. The sound produced when snapping your fingers is most definitely not the result of your bones vibrating. The sound from snapping comes from your middle finger compressing the air in the pocket you create between your ring finger and the palm of your hand.




Agreed. Completely wrong


Unfortunately, you are creating another myth. Myths are created when proper research is not done. Same in this case.


Just wanted to agree with the other three comments above. You really should do more research before attempting to advise people.


Joints are the meeting points of two separate bones, held together and in place by connective tissues and ligaments. All of the joints in our bodies are surrounded by synovial fluid, a thick, clear liquid. When you stretch or bend your finger to pop the knuckle, you're causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume. And as we know from chemistry class, with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking. :p It is the Internet.... google it.


yea... nothing you said in this article is even remotely accurate. seems like you just made this up and thought it sounded smart. it doesn't.


It's difficult to have any confidence in your knowledge of the functions of the human body when you publish such utter nonsense. Like Alex stated, a simple experiment will prove your hypothesis of the source of finger snapping noise wrong. I figured this out by myself before i reached my teenage years. I won't be visiting this site for information again!


When snapping your fingers, the sound comes from the impact of the middle finger against the base of the thumb/heel of the palm. Try putting something soft at the impact point, and see if you still hear the sound. The bones may flex a bit, and then "snap back" into shape (I don't know), but a simple experiment indicates the sound is from the impact.

I think I agree with Lindsey, at least on that point.


Ahh, Yoga Journal. I love it when you publish nonsense.
