U-Locks, Tepees, Croissants, Rolling Luggage

How It's Made – Season 20

Heavy steel is bent, hardened and coated to form the shackle of a secure U-lock. Fabric coverings are measured and sewn to fit the supporting poles of tepees; layers of yeast dough and butter are repeatedly folded, shaped, proofed and baked into croissants; and durable cases are fitted with wheels, handles and internal frames to make rolling luggage.
