People have different ways of doing it. I have 3 ways i can do it.
One is by simply pushing your fingers down towards the palm of your hand.
Another way is by pushing them back into the knuckle, and bending the middle joint of your finger. (if that makes sense..)
Another way is by cracking your fingers sideways. This is more difficult but it's what i do without realising :P Place your thumb on one of your fingers, and your index finger on the other side of that finger, then pull your index finger towards you.
I'm not encouraging you to do it as to all the rumours about Arthritis and wearing down cartilage and what not, but it's become a habit of mine when i get nervous or bored.. it also doesn't help that I'm a figit and need to be doing something constantly :P
When you crack your knuckles, the sound is produced by the release of gas bubbles—usually nitrogen—from the synovial fluid in your joints. This gas is released due to changes in pressure within the joint, creating a cracking sound.
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.
Yes, zebras do have knuckles on their legs. Knuckles are formed by the joint between two bones, providing flexibility and movement in the limb. Zebras use their knuckles to support their weight and move efficiently while running.
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".
Yes, brass knuckles are considered a weapon and are illegal in many jurisdictions due to their potential to inflict serious harm. Possessing or using brass knuckles can result in criminal charges.

You can't. They get bigger as you crack them. Don't crack your knuckles or you'll resort to big knuckles!
Not everyone can crack their knuckles. About half of those people who responded to an online poll could 'always' crack their knuckles, while a third could 'sometimes'. That leaves about 15 percent that said they could not crack their knuckles.
To crack your knuckles you simply pull back your knuckles in a 45 degree angle and it has to be up to 45 or else you might hurt your hand.

No. Cracking your knuckles does not cause your hands to swell.
Yes, depending on how often you do it. If you crack your knuckles a lot then you will continually have to crack them more unless you prevent yourself from doing so. Cracking your knuckles actually releases the nitrogen in between your joints.
The sound you hear when you crack your knuckles is actually the sound of carbon dioxide gas bubbles bursting.http://en.wikipedia.org/wiki/Knuckle_cracking
