I took the wrist strap off for my first game of Tennis because I thought it was dumb and would just get in the way. The thing flew out of my hands and hit the ceiling about 10 feet away! Then I tripped on GameCube cords while retrieving it.
My wiimotes have rubber skins for grip and stronger wrist straps just to avoid such an accedent, but I use a projector so I'd be throwing wiimotes through the wall.
How can you let go of the remote anyway? I mean you don't just let go of your racquet when playing.. tennis or something.
but why are his hands sweaty enough to the point where he can't keep his grip on the remote
