Knuckle Cracking Simulator Relieves Pressure Points, Drives Mom Nuts
"Stop doing that!!"... One of Mom's favorite and most frequent expressions (often followed by "You'll put your eye out!") can be provoked in so many ways, especially by cracking your knuckles. That slightly liquid sounding SNAP seems to rub the human pleasure center both ways - much like the stroke of fingernails on either one's back, or one's blackboard.
Funny how something that provides so much pleasure to one can cause so much annoyance to another... such is the case with cracking your knuckles. The Yubi-Poki virtual knuckle cracker will keep on cracking even after you've run out of knuckles.
Knuckles "crack" when bent along their axis and that distinctive sound can be coaxed twice per joint by bending first one way, then the other. The sound itself is produced not by a bone breaking, but by a bubble bursting within the joint. So: ten knuckles; 20 cracks... then what? Whip out your Yubi-Poki!
As the newest mugen gadget (one that imitates a favorite sound or action, like opening a beer or a box of candy), this inspired device looks somewhat wicked with its sextet of spikes circling either end but that may just be a play on the designer's concept of Brass Knuckles or wrist cuffs.
In actuality, the Yubi-Poki's spikes come in handy for stimulating acupressure points, something you may need to do after fellow subway passengers get fed up with your latest 20-minute knuckle cracking marathon. The Yubi-Poki costs just 500 yen (about $5.25) and comes in red, white or black. (via TokyoMango)
