10. Ceramic Grills, Pneumatic Punchers, Water Jet Fountains, Hollow Wooden Surfboards

Heat-resistant ceramic bodies are moulded, fired and fitted with vents, grates and metal hardware to produce efficient outdoor grills. Compressed-air cylinders and hardened tooling are incorporated into pneumatic punching machines; pumps, pipes, lights and electronically controlled nozzles become water-jet fountains; and wooden frames are covered with thin planks to create strong but lightweight hollow surfboards.
