Game description : Its a sad fact of life that knuckle popping is not a skill enjoyed by everyone, so our knuckle popping game will keep you up with everyone else. But if you want to go knuckle popping for real, here's how to do it. Firstly, clench your hands so they interlock then suddenly straighten your fingers and push slightly into each knuckle. That push should generate an immediate crack. Wait. Once you have popped your knuckles, it will take some time for the gas bubbles to redissolve into the synovial fluid. This prevents you from cracking them again right away. After you play this knuckle popping game, why not check out and play our other free weird online games?
