How It's Made

Season 30 Episode 8: Glass Sculptures, Racing Pulley Systems, Inductors, Medicine Balls

Molten glass is gathered, coloured and manipulated with heat and hand tools to create sculptural forms. Precision pulleys, ropes and mounting hardware are combined into systems used aboard racing sailboats; insulated wire is wound around magnetic cores to make inductors; and durable shells are formed, filled and sealed into weighted medicine balls.
