A method and system for accelerating an item with a rotating platform having a center point, a perimeter, and a radius from the center point to the perimeter. The method and apparatus deliver the item to a center area of the rotating platform by delivering the item to a first radial distance on the rotating platform, wherein the item has a first speed at the center area and tangential to the first radial distance. Also while the rotating platform is rotating, the item is advanced, in an apparatus-controlled orderly path, from the center area to a point relative to the rotating platform that is adjacent a perimeter of the rotating platform and that is located at a second radial distance greater than the first radial distance, wherein the item has a second speed tangential to the second radial distance and the second speed is greater than the first speed. Also while the rotating platform is rotating, the item is advanced, from the point, to a location beyond the perimeter of the rotating platform.
