If you do it right, you can get a nice crack sound. I've found that I can usually get at one from a freshly washed item of clothing (and towels) and it only cracks once per fresh wash. I don't understand the mechanism that causes it but find it satisfying for some reason.

"The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom."

(I agree that is a strangely satisfying thing. It does make hanging the wash up for drying slightly less tedious...)
