A handful of inventive New Yorkers have dreamed up an ingenious idea for getting relief from the summer heat, filling reclaimed trash dumpsters with water to create an instant urban oasis.

The improvised swimming hole in an industrial section of Brooklyn also has given a new meaning to the age-old term "dumpster diving," which until now referred to the New York bric-a-brac hunter's past-time of wading into refuse-filled containers in search of still-usable furniture and other discarded treasure.

But three inventive architects hit upon the idea of creating a community swimming pool in Brooklyn from unused trash containers for a new kind of dumpster diving.

The trio, part of the Macro Sea design firm, borrowed the giant, brand-new containers from the manufacturer.

"We put sand down to the bottom, then we put a top over that, then we put the water in -- it's 80,000 gallons," explained Jocko Weyland, artistic director at the company.
