Although your mama might have told you that cracking your knuckles will cause arthritis, you can’t help but continue to crack them. It’s so satisfying and it makes a cool cracking noise. But where does that sound come from? Well, read on to find out.

There is a gas-filled cavity in your joints that create a ‘popping’ sound when you move it.

A man named Greg Kawchuck led a study to find out more about knuckle cracking. He used an MRI and recording himself cracking his knuckles to see what would happen.

The study, cleverly called the ‘Pull My Finger’ study, used patients that were willing to have their knuckles ‘cracked’. For this project, they used a man named Jerome Fryer.

By the end of the study, the answer was revealed.

 

 

The patient’s fingers were attached to a cable and individually pulled while the MRI recorded the entire event.
The ‘cracking noise’ is created when the tiny gas-filled cavity collapses. It is caused by a bubble that builds up in the fluid and then ‘pops’.

In addition, experts have said that cracking your knuckles doesn’t actually cause arthritis. However, that doesn’t mean knuckle cracking isn’t bad for you. It can actually cause long-term damage to your joints and ligaments.
What are your thoughts on the video? Are you going to stop this addictive habit?
