Talking Trash

Designed with plants and humans in mind, there's some serious science in these brightly colored rain wands from Wisconsin. Go behind the looking glass at this Toronto mirror factory where huge panes of glass are scrubbed until squeaky-clean and then sprayed with liquid silver. Making light bulbs is a big turn-on for the team at this South Carolina factory where 1.2 million bulbs roll off the assembly line every year. There's nothing trashy about these old-school trashcans that begin life in Minnesota as giant rolls of galvanized stainless steel.
