In his recent post, Chris Gammell used astronaut ice cream as a fun example of how high tech innovation trickles down to consumer-level products. Seeing an image of astronaut ice cream in my G+ feed got me thinking about making some of my own. I managed to accomplish this with a harbor freight vacuum pump, some dry ice and various hoses and fittings. The process is known as freeze-drying and allows water to pass directly from ice to vapor, thus allowing the ice cream to maintain its physical structure while it is dried.

Here’s the famous footage of the Apollo 15 astronaut that dropped a hammer & feather on the moon to prove Galileo’s theory that in the absence of atmosphere, objects will fall at the same rate regardless of mass.
