Move the sliders to design your auto-rotator.[br]With scissors, cut all of the solid lines.[br]Fold all of the dotted lines (the two body lines first, the hook line second, and then the two propeller lines).[br]After folding the propellers in opposite directions, fluff them up so the auto-rotator looks like a capital Y.[br]Safely drop from a given height, and watch it automatically rotate gracefully to the ground.
