Canstruction is a unique food charity that holds annual design and build competitions to construct fantastic, giant sized, structures made entirely out of canned food. After the structures are built and the winners declared the creations go on view to the general public as giant art exhibits. At the close of the competitions all of the food used in the structures is donated to the local food banks for distribution to community emergency feeding programs. Since 2007, Canstruction Chicago has raised more than 450,000 pounds of canned food or 369,231 meals for the Greater Chicago Food Depository. This year's sculptures were built from 94,436 cans - more than 85,000 pounds of food.
