Project Runway is famous for its meltdowns, teardowns, fashion faux pas, and moments of total zany brilliance. Nothing reveals which designers are destined to be in and which are already out more than the show's famous 'unconventional materials' challenges. Whether designers are being dropped in the middle of a pet store, or told to make clothes out of burlap sacks, plastic tubing, and corn husks, it's always fascinating to watch.

Over the years Project Runway has delivered some truly insane challenges. On their way to be the next Alexander McQueen, hopefuls have had to play with everything from Hallmark cards to candy to actual trash. Some designers sank, some swam, some sweated it, and there were even some tears.
