A simple answer is "DON'T".
If you want to do an exercise that may help relieve tensed muscles in your back, and maybe when you do that your back will naturally "crack" all by itself, try this: Lean back against a wall so that your entire back is against it and your feet are about shoulder width apart and a foot, or so, away from the wall. Now use your leg muscles to push the small of your back gently against the wall. You may even turn your upper body to the left or right to find the right spot and the right angle. It should be done very slowly and under control. It should feel like a mild stretch. When you find the right spot, press gently into it with your legs pushing that part of your back into the wall, and then the most important part: breathe.
Sometimes when I do this there is a little "pop" that people refer to as cracking. Actually nothing is really cracking, and most definitely it's not your bones. It's really tiny air pockets that fill with gas temporarily and make a popping sound when they form. It's all natural as long as it is done slowly and a part of relaxation. I put both of my hands behind my back on my rib cage and push arching my back. Also you can put your hand on one side of your rib cage on the back and push doing this on both sides.
Go to a chiropractor since you can hurt yourself like I did...
between lower vertebrae I can't figure it out, if it doesn't heal I'll have to go to a doctor.
i did not write the first part i am just adding on to it
if you don't want to go to a chiropractor just find a chair ( the back of the chair must end about 15-20 cm's under your armpits)
sit on it and lean over it until you hear your back crack
like the person above said the best thing 2 do is go to a professional
stretch
yes they can
dont be scared!
You can go to the dentist and have them fill in the crack or file the crack down.

use your hands and feet while sitting down or laying down on the board.
water retention and circulation. try laying down on your back and elevating your leg while you sleep at night.
Egg shells are known to be stronger when standing upright. This is why we crack eggs open on the side.
well, you can't fall. You can trip for sure, that sudden jolt you experience when you trip while standing can happen while laying down.
you dont kiss at all.
Only a second or two, depending on how quickly she has to get up, and whether she's laying on an incline or not.
