That's what triggered this project: We bought some "astronaut ice cream" at the museum recently and the kids asked if we could make it at home. I'm picking up some dry ice tomorrow morning to give it a shot.
It's a really delicate process. I've built an infra-red heating rack that helps a lot: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RvJgVv9kXG4.html
Kinda! Check out a later video in this series. I rig up a chiller to cool the ethanol rather than dry ice. It works much better and is far less expensive. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7W1A2OV-K6g.html
Ben used the tungsten filament bulb to get the heat directly onto the food. Because if the food is not in good contact with the walls of the container, warming it in a waterbath or something won't work really well. If the glass is really passing infrared idk.
