Falling Chimney Paradox

Different points accelerate differently; model may bend/break in segmented version. Ask students to predict what will happen. Tip long ruler from vertical and watch top/sections. Key idea: Rotational motion means farther points need greater tangential acceleration. Ask: Why doesn't every part fall the same way? Safety and cleanup: Use light model away from students. https://www.google.com/search?q=%22Falling+Chimney+Paradox%22+science+demonstration+experiment
