Wii Safety Precautions
"Hold the Wii Remote firmly and do not let go. Even while wearing the wrist strap, make sure you don't let go of the Wii Remote during game play and do not use excessive motion. For example, in Wii Sports bowling, the proper way to let go of the ball while bowling is to release the "B" button on the Wii Remote--DO NOT LET GO OF THE Wii REMOTE ITSELF. If you are having so much fun that you start perspiring, take a moment to dry your hands. If you use excessive motion and let go of the Wii Remote, the wrist strap may break and you could lose control of the Wii Remote. This could injure people nearby or cause damage to other objects."
