Canstruction is no simple canned food drive. It's a design competition and show that challenges 24 architecture and engineering firms to create super-sized sculptures that will help feed hungry families—and inspire others to do the same. The gravity-defying creations, from high-top sneakers to the Brooklyn Bridge, are made from tens of thousands of stacked cans by Thornton Tomasetti, Skanska USA, and Arup, among others. The event, a collaboration between the Society for Design Association, City Harvest, and The American Institute of Architects, also draws a team of judges including World Trade Center Memorial designer Michael Arad and HGTV star Chip Wade to choose winners in categories such as "Best Meal" and "Best Use of Labels." But the true culmination comes on the show's final day when "DeCanstruction" begins and all the food is distributed to hungry families in time for the holidays. Visitors are encouraged to bring a can of food and help organizers reach their goal of collecting 160,000 pounds of food, which can feed 140,000 people.
