Here is my best one so far. it is a springboard. fold the paper into thirda then make a tube, Do not crease. Then cupboard fold both sides to the center. Then book fold to the same center. Form the centerfold over a table corner so there is a radius and not a strong crease. Dent one end slightly so the ball stays in place till the release. Stick your finger in the tube place the ball on top then and slide your finger out to release. It usually goes straight up. Anywhere from 12 to 20 inches. Kate
