The sound produced when you pop your knuckles is primarily due to the rapid release of gas bubbles that form in the synovial fluid of the joints. When you stretch or bend your fingers, the pressure in the joint changes, allowing these bubbles to collapse or pop, creating the characteristic sound. This phenomenon is known as cavitation. The sound itself is not harmful and does not indicate any damage to the joints.
