This gimmick will make a loud "bone cracking" sound. With it you can surprise, and freak out your friends by pretending that you are cracking your neck (or your elbow, knee or knuckles). The gimmick is small, easy to hide in your hand and to dispose of after the prank.
 
Surprising and fun!
 
• Makes a nice "cracking" sound.
• Easy to use, skin color and practical to hide.
• It can be used simply as a gag or to "break the ice" with spectators.
