Instructions
Hold the Wii Remote in your preferred hand with the remote's sensor pointing toward the Wii. Use the wrist strap to ensure you don't throw or drop the remote accidentally.
Press down the "B" button on the back of the Wii Remote while raising the remote to your chest. Hold the Wii Remote as if it were a bowling ball that you are preparing to throw.
Swing your arm as if you were throwing a bowling ball. In one continuous motion, pull your arm down and back until your arm is outstretched behind you, and then gently yet quickly sweep your arm forward.
Twist your hand in the direction you want the ball to curve immediately before your arm reaches the end of the throwing motion.
Release the remote's "B" button immediately after you finish twisting your hand and swinging your arm.
