The basic design for this project is to have a ‘flowing river’. I purchased an old non-motorized treadmill and I added a motor to it. I could have just got a motorized treadmill to begin with but I was concerned about the weight. Basically any belt that is motorized will work to show this demonstration. As for the boats, I used some wind-up toys from a childrens store that worked great for the simulation.
