Aluminum Canoes, Wooden Stave Bowls, Wheelchair Accessible Vans, Marimbas

How It's Made – Season 21

Sheets of aluminum are formed and joined around supporting ribs to create lightweight canoes. Angled wooden staves are glued into hollow forms and turned into bowls; vans receive lowered floors, ramps and other accessibility equipment; and carefully selected wooden bars are cut, tuned and mounted above resonators to produce marimbas.
