The best I ever did was freeze a banana

Found on Blogdex: In this month’s Popular Science, Theodore Gray (of Mathematica fame) gives the recipe for liquid nitrogen ice cream. Damn. Wish I had thought of that when I was freezing bananas in the lab after hours to amuse and impress friends. (Disclaimer: I only did that once, and it was a bitch to clean up. Fellow smart-ass physics undergrads, you’ll try it once and then curse me out.)
