S19E13: Space Pens, Reef Aquariums, Metal Caskets, Composite Bike Wheels

Pressurized ink cartridges and precision ballpoint tips are assembled into pens designed to write in extreme conditions. Glass or acrylic panels, lighting and filtration equipment are combined into reef aquariums; sheet metal is formed, welded and upholstered to produce caskets; and layers of composite fibre are moulded and cured into lightweight bicycle wheels.
