lol the bones in that picture make a cracking sound because the 3 fingers are clearly broken.
Air escaping the joints releasing tension. But if you crack your knuckles, knees, neck, fingers, etc. too much the bone starts to wear out leading to major problems
I have heard from doctors saying that there are air bubbles in our joints. So when we stretch or push, you are actually cracking the air bubbles.
It is said that we should not be doing it too much like cracking our fingers.
this noise is air escaping the joints.
Wow...i've always wanted to know the answer to that myself, never realised it was just air!
