Kelp Caviar, Luxury Sailboats, Dental Crowns, High-Performance Engines

How It's Made – Season 15

Dried kelp is ground and blended into a gel before being formed into caviar-like pearls and packaged in a variety of flavours. Fibreglass hulls, decks and hand-finished interiors are assembled into luxury sailboats; digital models guide the production of ceramic dental crowns; and precision-machined components are combined and tested in high-performance engines.
