Eli5: Why can you only pop your knuckles once?

146 views

Why is it that when you pop your knuckles or other joints you can only do it once and then they won’t pop again for a while?
I know that the pop is from a gas bubble forming and cavitating but why candy you do it a second time?

What is popping is a small gas bubble. Once it’s popped there’s no more bubbles, and you need to wait for more to form

This is a good short vid explaining it

I can actually pop the first joints in both pointer fingers as often as I want with no refractory period. Am I a mutant?

I have a toe that pops repeatedly. Probably something to do with breaking it a few times skateboarding.
