Roller Coaster Illusion Traveling Up an Incline
Car Travels Uphill
A toy car with a paddle wheel and a shaft on both ends traveling upward on a chute in which water is flowing down, is shown in the accompanying sketch. The paddle wheels travel in a reverse direction causing the ends of the axles to roll on the edge of the chute, thus carrying the car up the incline. If a rack is used on each side of the chute and a small pinion on the ends of the axles, a positive upward movement of the car will be obtained.
