Hamza is packing up for a nice beach vacation, but he can't fit all his stuff into his suitcase! Origami to the rescue - he takes a nod from the 400-year-old art of Japanese paper folding to make things with a lot of surface area take up less space! We learn about the math hidden in origami: reflection symmetry (line symmetry), vertexes, geometric shapes in origami, folded objects in everyday life, folding in the earth's crust, different folds and stabilizing techniques for paper airplanes, the history of origami, engineering applications using origami, strength in folds, modular origami constructions, and medical origami robots.
