Monday's gravity race down Church Hill will be the last unless every cart stops. Grandma Rosa has a cart she began in 1964 and never finished: GOING DOWNHILL, AND STOPPING. Ollie is sure a heavy cart goes faster. He fills it with iron, and the hill shows him what he got wrong.

About the Inventor's Workshop series
Inventor's Workshop is a series of illustrated adventures for readers aged ten to twelve about physics, engineering and technology. Ollie, who builds first, and Amara, who measures first, take half-finished machines from Grandma Rosa's shelf and finish them to solve real problems, with a stubborn homemade robot who refuses anything unsafe. Each book delivers one science or technology topic through a machine that works by real physics, and shows what it trades.
