Wood Toys, Retro Toasters, Laboratory Furnaces, Aerogel

How It's Made – Season 27

Selected wood is cut, shaped, sanded and decorated to create traditional toys. Metal housings, heating elements and timing mechanisms are assembled into retro-styled toasters; insulated chambers and precision temperature controls become laboratory furnaces; and a wet gel undergoes specialized drying that replaces its liquid with air to produce extremely lightweight aerogel.
