Me and my friends made this up during a party we gave about 10 or so years ago. We were drinking champagne and shooting gelatin shots. We chunked up a gelatin shot and added some to a glass of champagne. A few years later I mentioned this idea to some guests at the restaurant where I was bartending. About 3 months later a local bar was advertising these drinks.
Please note the additions of berries and lemon-lime soda when using the magazine version of this recipe.
