Synchronized Knuckle Cracking

Ever wondered what it would sound like if a few thousand people cracked their knuckles at the same time? And in a room with good acoustics?

Well, here it is.

As a fan of knuckle cracking, I approve.

By the way, did you know that it is completely unsubstantiated that knuckle cracking can have ill effects, such as arthritis?

In fact, a certain Dr. Donald L. Unger of Thousand Oaks, California, USA, received a Medicine Ig Nobel prize in 2009 for his 1998 paper titled "Does knuckle cracking lead to arthritis of the fingers?".

In it, he investigated a possible cause of arthritis of the fingers, by diligently cracking the knuckles of his left hand — but never cracking the knuckles of his right hand — every day for more than sixty (60) years. He found none.

Now, that's devotion.
