At this year’s 19th annual Canstruction: Exhibition, a Food Drive and Design Contest at the World Financial Center in New York City, 26 design and architecture firms have built gigantic, gravity-defying sculptures from thousands of cans of food. Over 100,000 cans were turned into works of art to help City Harvest feed hungry New Yorkers. The exhibition, free to the public, is up now until November 21, and encourages visitors to donate high-quality non-perishable foods, such as tuna, beans, and canned vegetables. More information on the exhibition can be found here. More images after the break.
