Via Todd Dailey and Kottke, we saw the Ziploc Big Bags and thought: "cool!" Many of our customers are making this, DIY style with Clip-n-Seals. The exact use of the Space Mondo that NASA ordered is still a mystery, but it's even bigger than the Big Bags. Girl Hacker also posted on it and jokes about using them for, "a pseudo-vacuum seal". Our customers actually do that!
