After answering the question of how the space potty works, astronaut Mike Massimino now visits the Advanced Water Recovery Systems Development Facility at NASA's Johnson Space Center. Chemists have been working hard to develop a next-generation trash bag for future exploration, including testing different forms of trash...and fake vomit. Watch as Massimino and the scientists lend their noses in the name of exploration and see if NASA's mixture is potent enough in this edition of "NASA Behind the Scenes."
