A flat sheet of paper collapses easily under pressure—it lacks structural strength! But once it’s folded or creased, everything changes. Those bends form ridges that act like tiny support beams, distributing weight more evenly across the surface. The folds add rigidity, reduce bending, and allow the paper to bear much more load. It’s the same principle engineers use when designing bridges and buildings—with arches, corrugation, and beams turning simple materials into strong structures. Follow @t
