A friend of mine claimed you can make a laser from a gin & tonic, and so I had to find out more. It turns out that not only can you make a very poor laser using ethyl alcohol, you can also make one from Jello! Well, not the actual Jello like you’d find in a grocery store – instead it would be a non-toxic variation of the traditional dye laser held in gelatin rather than liquid — but edible and lasing none-the-less!

Stephen Wilk explores these and more edible possibilities in this article for Optics & Photonics News (embedded magazine reader). Alternative source: (google docs)
