Our dad checked a book called Mad Science out from our library last week. It was written by Theodore Gray, the author of the Gray Matter column in Popular Science magazine. All of the experiments in the book were cool, but most involved high heat (as in well over 1,000 degrees) or toxic chemicals like Mercury or Chlorine Gas. As these experiments were a little bit beyond our league at the moment, I looked for some experiments that wouldn’t kill, maim, or seriously injure us if they went wrong. We found the perfect one: Dry Ice Cream.
We’ve used dry ice before and we figured that this experiment would be perfect, because, as Luke said “it combines two of my favorite things, science and food.”
It was surprisingly easy to make this ice cream, and it tasted very good (although it had a slightly carbonated taste from the Dry Ice). The ice cream was extremely creamy, since no ice crystals had time to form in the 2-3 minutes it took for our ice cream to completely set up.
Everyone in our family was very impressed with the dry ice cream, and wanted more. Maybe we could do liquid nitrogen ice cream next time…..
