A waterfall diversion apparatus is provided consisting of a modified cylinder in which a supply of water which normally cascades over a portion of roller coaster track as a waterfall is temporarily diverted as the passenger carrying cars of the roller coaster pass underneath before the diverter mechanism rotates back to a non-diverter position and the waterfall resumes. The rotating diverter member is a cylinder-like device having a plow like inner divider which when rotated into the path of the water fall diverts the water to the ends of the cylinder where it continues in an outward path to the left and right of the passenger carrying cars of the roller coaster. The modified cylinder is normally obscured from view by the waterfall passing over the exterior surface of the diverter member. As the passenger carrying cars approach the waterfall it trips a mechanism which causes a pneumatically or hydraulically controlled piston to rotate the cylinder until the scoop and plow-like diverter blade moves to an operative position just as the passenger carrying cars are underneath. The water being divergently ejected from the ends of the cylinder, appears to be splashing off of the passenger cars. The timing of the diverter mechanism is set so that even the ride occupants are convinced that they are going to pass through the waterfall. After passing under the diverted waterfall, sensors trip the piston directing the cylinder into a retracted position thus allowing water to continue along its normal arterial flow.
