The Science Behind Your Favourite Habit

Your finger joints contain space between them. This space is filled with fluid. More specifically, it's known as the “synovial fluid”.

Now, the pressure between your joints has decreased, leading to the release of gases, such as oxygen, nitrogen and carbon dioxide. This gas is released in the form of bubbles, also known as “cavitation”.

And yes, you guessed it right. That satisfying crack sound we hear every time we crack our joints is created by the popping of those bubbles.
