[00:00:00]Everyone loves that satisfying crack when you twist your back, but what's actually happening inside? Inside your joints is a special fluid. When you stretch or twist your back, pressure drops suddenly causing tiny gas bubbles to form extremely fast. These bubbles collapse in a split second. [music] This is called cavitation.

[00:00:24]That loud popping sound [music] you hear, it's microscopic bubbles exploding.

[00:00:30]The crack releases built-up pressure, which is why it feels so good afterwards.

[00:00:36]But doctors recommend not [music] doing it too often. It can irritate your joints over time. So next time you crack your back, you're really just popping tiny bubbles. Mind blown? Like and comment. [music]
