Ever since I was a kid, I've adored the crunchy/creamy sweet treat of astronaut ice cream. Now that I live just five minutes from Johnson Space Center, the freeze-dried confection is the top request when we take visiting friends to the gift shop at Space Center Houston. There is just something idyllic and iconic about the space-age dessert. Ben Krasnow shows how you can build a freeze dryer to sublimate the water from regular ice cream to turn it in to the crunchy astronaut ice cream we all know and love. Bonus point for the mix of science and sugar!
