Abstract: A diverse variety of high speed gravity cableway rides in which a rider on a pulley block car descends a mountainside and generally stops by frictional forces, due to the design of the cable arc, before hitting the lower cable support point. In some forms, the rider may control his speed with a braking device and use a ski-lift to return to the top of the hill. In all form suitably safe embarking and disembarking platforms or procedures are employed.

Abstract: Self-illuminated luminous game balls for nighttime play which may be either inflated or self-supporting and consist of various apparently ordinary looking balls with portable electric lighting assemblies or chemi-luminescent lights, including fireworks inside them for exciting novel effects.A shaft manufactured integrally within a toroidal form is disclosed which firmly holds an electric or other lighting assembly such that said lighting assembly may be removed in its entirety for servicing or replacement, through a flush, waterproof cover designed for such purpose.A conveniently located On-Off switch is also located such that it may be actuated without deflating the ball, and its electrical connections to the batteries and bulbs are designed so that the center of gravity of said heavy batteries and other electronics are mounted near the center of gravity of said ball for optimum handling and closer simulation of a normal play ball.
