A great ball contraption seesaw is like a seesaw toy with a long lever whose fulcrum is near the center. It picks up balls from the in basket when the end nearest the basket goes down. When that end comes up, balls roll to the other end. When the far end comes up, balls are dumped into the next module and the cycle repeats.
