Smithsonian Antarctic meteorite storage facility. See, when it isn't kicking up the video-games-as-art debate or showing off our future overlords, the Smithsonian also dabbles in the study of fallen rocks from space. So just exactly how clean is the Smithsonian's Meteorite Clean Room? Well, let's just say it's highly unlikely that you'll find microscopic traces of that peanut butter and jelly sandwich that the intern had for breakfast on any of the facility's 15,000 Antarctic meteorites. As shown in the behind-the-scenes video after the break, the research facility goes to great lengths to prevent sample contamination, from the surgical-looking staff prep to dry nitrogen storage. After all, no researcher would like to be the poor sap who studies a contaminated meteorite and mistakenly announces to the world that Mars not only had peanut butter but jelly as well.
