Rob Maslin is the designer behind the inventive and thought-provoking fish tank known as 'Free Lunch.' Free Lunch is one part fish tank and one part herb and vegetable garden.
The fish and plants in Rob Maslin's Free Lunch have a symbiotic relationship. The plants filter out the waste water that the fish produce, which in turn helps them grow and keeps the tank clean. A standard-sized tank could support a small herb garden on a four-week cycle. Everyone wins with Rob Maslin's Free Lunch.
