It's obviously not cracking the bone, but what is it?

When you crack your knuckles, you're essentially pushing the joint into or out of its normal position. A thick, clear lubricant called synovial fluid is found in the joints between your bones. When you crack your fingers, you cause the bones to pull apart, and the pressure on the synovial fluid is reduced. Bubbles form and quickly expand and then burst. Snap, crackle, pop go your knuckles!

My friends dad is a chiropractic and he says it is good for you to crack your knuckles.
