I'm often asked how to make glow-in-the-dark cocktails. This can't really be done, but you can make blacklight reactive drinks and use glow-in-the-dark accessories for some neat effects.

Tonic water is made from quinine. This bitter-tasting soda-like water is made from the bark of the Cinchona tree, found in the Andes Mountains. It was originally used to treat malaria. It helps to reduce fevers and leg cramps as well. The neat thing is that quinine is also photochemical-reactive. That means it glows blueish-white when exposed to ultraviolet or blacklights.
The fluorescent quality is best when you use a lot of tonic water in your drink. The following is a list of drinks to make that will glow.

Make these in a highball filled with ice. Use 1 oz. of liquor in each.

Vodka or Gin & Tonic
