back in december some of my little internet friends were talking about cool sciencey things and i was also in the middle of a candymaking frenzy and somebody or other came across some recipes for candies that fluoresce under blacklight and i thought i'd try my hand at it.
the key is that quinine fluoresces under blacklight, so tonic water does, too.
and if you make your candy with enough tonic water in it, it will also flouresce.
it's hard to cook it to the point that it will be solid without the sugar caramelizing a little too dark to make the glowy effect dim, but look at these. don't they have the most fantastic golden color?
