Brachistochrone Ball Race

The longer-looking curved path can win. Ask students to predict what will happen. Release balls simultaneously from same height to same end height. Key idea: Dropping steeply early builds speed sooner, reducing total travel time. Ask: Why can a longer path be faster? Safety and cleanup: Balls contained in tracks. https://www.google.com/search?q=%22Brachistochrone+Ball+Race%22+science+demonstration+experiment
