How It's MadeSeason 152010 · 13 episodesEpisodes1Kelp Caviar, Luxury Sailboats, Dental Crowns, High-Performance EnginesDried 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.2Leather Briefcases, Crop Dusters, Corn Whiskey, Drag Racing ClutchesBridle leather is cut, reinforced, hand-stitched and fitted with polished hardware to create traditional briefcases. Welded airframes, chemical hoppers and spray systems are assembled into crop-dusting aircraft; ground corn is fermented and distilled into whiskey; and machined plates, friction discs, springs and levers become drag-racing clutches.3Train Rails, Desalinated Water, Racing Wheelchairs, ParquetryRecycled steel is melted, cast and rolled into long sections of train rail before being straightened and inspected. Seawater passes through filtration and high-pressure membrane systems to become drinking water; lightweight tubing is shaped around an athlete’s measurements to build a racing wheelchair; and precisely cut hardwood pieces are arranged into decorative parquet flooring.4Flight Simulators, Bookbinding, Greenhouse Tomatoes, Hurricane-Proof ShuttersCockpit controls, computer-generated displays and motion systems are integrated into realistic flight simulators. Printed sheets are folded, sewn and enclosed in handcrafted covers using traditional bookbinding methods; tomatoes are cultivated under carefully regulated greenhouse conditions; and reinforced shutters are fabricated and tested to protect windows from hurricane-force winds and flying debris.5Worcestershire Sauce, Lawn Bowls, Radio-Controlled Model JetsA complex mixture of seasonings and fermented ingredients is matured, filtered and bottled as Worcestershire sauce. Dense synthetic blanks are shaped, weighted and polished to give lawn bowls their distinctive curved path, while lightweight composite airframes, radio-control equipment and miniature turbine engines are assembled into high-performance model jets.6Pipes, Rock Climbing Gear, Leather Bike Saddles, Luxury Sports CarsFire-resistant briar wood is drilled, carved, stained and fitted with a vulcanite mouthpiece to create a smoking pipe. Aircraft-grade aluminum is forged and heat-treated into carabiners and other climbing equipment; wet leather is moulded over a metal bicycle-saddle frame; and lightweight chassis, powerful drivetrains and carefully finished body panels come together in luxury sports cars.7Replica Foods, Traffic Cone Dispensers, Rocking Horses, London TaxisReal dishes are used to make silicone moulds from which durable plastic replica foods are cast, trimmed and hand-painted. Welded frames, motors and robotic arms form machines that deploy and retrieve traffic cones; hardwood pieces are carved and joined into traditional rocking horses; and purpose-built bodies, drivetrains and passenger compartments are assembled into London taxis.8Miniature Furniture, Garden Steam Locomotives, Hovercraft, Folding BicyclesCraftspeople reproduce the joinery, upholstery and finishes of full-sized furniture in miniature. Precision-machined boilers, cylinders and running gear become working garden steam locomotives; lightweight hulls, flexible skirts and propulsion fans are assembled into hovercraft; and hinged frames with secure locking mechanisms allow bicycles to fold into compact packages.9Crosscut Saws, Haggis, Collectible FirearmsSteel blades are cut, toothed, hardened and sharpened to produce crosscut saws capable of slicing cleanly across wood grain. Organ meats, oatmeal, onions and seasonings are prepared and packed into traditional haggis, while machined metal components and carefully fitted wooden stocks are finished and assembled into collectible firearms.10Alligator Bags, Lockers, Bench Planes, Deployable Flight RecordersSelected alligator hides are cut, reinforced, stitched and finished into luxury handbags. Sheet metal is punched, folded and joined to make storage lockers; cast bodies, sharpened blades and shaped handles become woodworking bench planes; and protected recording units are enclosed in deployable housings designed to preserve aircraft data after an accident.11Grapples, Flavorings, Dog Sleds, Athletic ShoesHeavy steel parts are cut, welded and fitted with hydraulic mechanisms to create industrial grapples. Natural and synthetic ingredients are extracted, measured and blended into concentrated food flavourings; shaped wooden components are joined and reinforced to build dog sleds; and layers of fabric, foam, rubber and supportive materials are cut, stitched and bonded into athletic shoes.12Retractable Cords, Wood Frame Sports Cars, SushiInsulated electrical conductors are wound around forms and heat-treated so they repeatedly return to their compact coiled shape. Traditional timber frameworks are shaped and joined before receiving metal body panels and mechanical components in wood frame sports cars, while seasoned rice, seafood, vegetables and seaweed are carefully prepared and assembled into sushi.13Leather Wallets, French Horns, Soy Sauce, Children's Ride-On CarsLeather is cut, thinned, lined and stitched into wallets with precisely fitted pockets and compartments. Brass tubing is bent, joined and equipped with valves and a flared bell to create French horns; fermented soybeans and wheat are aged, pressed and filtered into soy sauce; and moulded bodies, electric motors, batteries and controls are assembled into children’s ride-on cars.Season 3Season 4Season 5Season 6Season 7Season 8Season 9Season 10Season 11Season 12Season 13Season 14Season 16Season 17Season 18Season 19Season 20Season 21Season 22Season 23Season 24Season 25Season 26Season 27Season 28Season 29Season 30Season 31Season 32
