Canstruction® is an extraordinary annual design competition and a unique food charity in the world. Now on exhibit are the structures made entirely of unopened cans of food. Teams of architects, engineers, contractors, and the students they mentor created these sculptures for the competition. After public public viewing, they are dismantled and donated to City Harvest for distribution to those in need. Admission is free, but visitors are asked to bring a can of high quality food to the exhibition’s collection station. The exhibit runs through November 13 at Brookfield Place World Financial Center at 220 Vesey Street.
