Marblevator, Hill Climb (and Descent)! As the old adage says, what goes up, must come down! "Marblevator, Hill Climb (and Descent)!" reinforces that adage thanks to an N20 styled 200 RPM 6VDC gear motor, a 1000 mAh lipo battery, a speed controller and a lipo battery charger in order to create the physics violating illusion of climb and descent coiled motion. And how does it work? Well it starts with a 6.35mm (1/4") spherical magnet located within the tower that is rotated by a four finned barrel. Without any assistance, the spherical magnet sits below the barrel fins and does not move. However, when an 8mm ball bearing is allowed to descend to the start of the track, the spherical magnet is attracted to the ball bearing and is lifted up into the barrel fins which rotate the spherical magnet around the tower interior. And thanks to the magnetic attraction between the spherical magnet and the ball bearing, the spherical magnet spirals up the coiled track to the top. At the top, the ball bearing is stopped by the track end cap while the magnetic sphere continues to rotate within the fins until the magnetic force is no longer viable. At that point, the magnetic sphere drops down to the bottom of the tower awaiting the descent of the ball bearing where the process repeats. As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.
