What's Going on Here:
Launch your Magnus Flyer.
It moves forward, begins to spin, and lifts up.
When it moves forward, it slams into the air in front of it. The air has two ways to go: above the cups or below the cups. The spin on the cups help the cups grab the air in front of them and carry it over the tops of the cups, similar to a waterwheel. Once the air is behind the cups, the cups dump off the air and shoot it down. As a result of the air being pushed down, the cups are pushed up. The air shoots off the cups in one direction and the cups move in the opposite direction. Newton explained it as "for every action, there is an equal and opposite reaction."
