One display is known as a marble pump. Patrons turn a wheel and a series of blocks go up and down like stairs. Marbles raise and climb one by one until they roll downwards. “I had a man from
Western come here who spent 45 minutes trying to figure out the engineering of it,” says Suzanne Goodell, publicity and outreach coordinator for Mindport. “It looks pretty simple, but when you start taking into account all the different angles and movements, it’s really complex.”
