Things You'll Need
Instructions
Place the Wii remote wrist strap on your wrist and hold the remote in your strong hand.
Stand facing the screen. Hold the Wii remote so it is facing up, but tilted forward.
Throw the Wii tennis ball up by pressing and releasing the A button on the face of the remote or by flicking your wrist up.
Study the ball as you toss it up a few times. Watch for the moment the ball is at its highest point, almost lingering in the air for a split second.
Flick your wrist downward when the tennis ball is at its highest point. This will create a smoking white flame on the ball and will launch the power serve into the opponent's playing field.
