For the best Galaxy Glow Martini, use freshly squeezed lemon juice for a bright, tangy flavor. The tonic water is key for the glowing effect under black light, so be sure to add enough. A small pinch of edible glitter will give your drink a mesmerizing sparkle—perfect for photos! Make sure to serve it in a clear martini glass to showcase the glowing, cosmic look. Enjoy it in a dark room with black light for the full galaxy experience!
