A chute fabricated of a polymer has an arcuate leading edge, an arcuate trailing edge, a left edge, a right edge, a top surface, and a bottom surface. The chute has a centerline extending between the leading edge and the trailing edge. The centerline is equally spaced from the left edge and the right edge. The chute is curved with an axis of rotation parallel with and elevationally above the centerline and spaced from the centerline and the top surface.
