It's the release of synovial gases that reside inside of the joints. The synovial fluids and gases are essentially lubricants for joint movement. The popping sound is like a bubble of this gas/liquid bursting. It is actually not harmful or damaging in most cases.
If you pull on the joint capsule, the walls of the capsule expand and lower the pressure on the fluid inside it. The gas then comes out of solution suddenly and forms bubbles, which then pop making a popping noise.

NO! Popping your knuckels just pushes the joint out and back into its normal postition. The sound that comes from popping them comes from the gas of the fluid that is between the bones as they are poppin in the fluid. It wont make your knuckles larger, but you might make your grip weaker if you do it too much cause it can start causing problems, such as arthritis.
Yes, fleas do pop sometimes when you squeeze them.
its air leaving the space between your fingers that's why there's a "popping" sound when done.^_^
The word pop means to pop (verb reg) meaning to explode when you pop a balloon it explodes making a popping noise. Pop is also a contraction of 'popular' when discussing current music, culture and art.
Of course. You can pop it really hard, or bending it the wrong way. I don't recommend trying this. (you can also pop any limbs or phalanges do it this way, although the proper way of saying "popping out of its socket" is actually "dislocation".
They used to say that cracking your knuckles would give you arthritis. A doctor friend of mine says that that is not true; that "popping" your knuckles is just releasing gasses in the joints. However, the danger with cracking your knuckles is over-extending them or flexing them too far, which could cause pulled muscles or eventual joint damage.
This means that in the chemical reaction that occured, hydrogen (H2) gas was produced. The splint will make the popping noise because literally there is a small explosion occuring, and water vapor will form.
There are a number of causes that could lead to tiles popping when a pool is drained. This could just be stress on the tiles.
Sometimes it may pop/spatter slightly when a droplet of water comes into contact with the oil; the instant evaporation causes the popping sound.
