Inspired by Chris Gammell’s post about “trickle down techonomy,” Ben Krasnow posted this how-to video on making your own Astronaut Ice Cream. He used a vacuum pump, dry ice, and various hoses and fittings to freeze dry ice cream that can be easily enjoyed any time you’re out in space or even on terra firma. [via CRAFT]

This is why I love America- there are still people around who were inspired
by our science focus 50+ years ago, and figure out how to make something this complicated at home, because it can be done.

This is how to get kids to like science! Teach them this is how they make ice cream for astronauts. Can you image a kids face when they taste this, and know they learned science to do it? They’d love learning and science for the rest of their lives. Science really is cool, and there’s no limit to the wonders you can create with it and critical thought. Awesome project!

Certainly a very innovative approach, however this ice cream does not look yummy at at … ;(

  I’m guessing you’ve never tried astronaut ice cream before. It tastes like ice cream (well, because it is) but the texture is totally different. Give it a try sometime!

That is fantastic! Great video showing the steps and reasoning.

My chemistry teacher in high school once freeze-dried some marshmallows. I don’t remember the process (it was awhile ago…*grin*), but I do remember it involved liquid nitrogen. I would love to see that again! They were crunchy and delicious!

Oh, and now I want some freeze-dried ice cream…mmmm
