I've been cracking my knuckles, back, neck, knees, etc. for years now and my doctor tells me it's tiny air pockets. He said as long as it doesn't hurt, it's perfectly ok to continue cracking joints.
popping air bubbles trapped in your joints. Forcing so joint to crack however can cause problems later in life
Air bubbles, same as in cracking knuckles...
pottery pieces crack during drying because the clay shrinks too fast and unevenly. If drying is controlled by wrapping pieces in plastic and allowing them to dry slowly, they won't crack usually.
Yes, air will enter rock cracks. But, if water fills the crack, during a deep freeze, the expansion of the water, as ice forms, will often widen the crack (even to split the rock).

What's really happening when you "crack" your knuckles:The noise you hear is actually the creating of small bubbles of nitrogen. This is an absolutely harmless thing to do despite all the "old wife's tales" to the contrary.
Skin cracks when it is cold because the air is extreemly dry and sucks the moisture out of your skin.
To remove the air bubbles, open the stopcock and the air bubbles will remove
if you have a crack in your neck once in a while it's ok to crack it like with anything, but repeatedly & obsessively cracking your neck is not good for you as the 'crack' noise you hear is actually air bubbles popping away at your bones & can permanently damage them.
No. The cracking sound is caused when the small bubbles of air in between your joints pop. It does not cause any problems. People who say that is causes damage are passing on a myth.
Yes they do, the chemicals from the air find a little crack in the paint and then rust causing bubles. :) Hope this helps :) :) :)
The pavlova must stand to cool in oven to prevent cracking. If it cracks it means the air collapsed without solidifying the meringue.
