Cracking Joints
Cracking or popping of joints is the action of moving joints to produce a sharp cracking or popping sound. This commonly occurs during deliberate knuckle-cracking. It is possible to crack many joints, such as those in the back and neck vertebrae, hips, wrists, elbows, shoulders, toes, ankles, knees, jaws, and the Achilles tendon area.

“Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.”
