So my dad and I have disagreed on this subject for about 10 years now. I told my dad that research shows that cracking your knuckles is cavitating the nitrogen bubbles. To which he said, “No it can’t be. that would cause a lot of damage to your body.” His point is well taken because cavitation does output a lot of energy and is notorious for destroying things (e.g. boat propellers). I crack my knuckles every day, shouldn’t my bones get destroyed like boat propellers do?

It’s not cavitation, it’s just gas coming out of solution. Cavitation is specifically the vaporization of the liquid due to a sudden decrease in pressure. The actual fluid in your joints isnt vaporizing, just the nitrogen *in* the liquid.
It’s much more like opening a can of beer. Yes gas, no cavitation.
