Now, add your alcohol and a few drops of black food coloring. Note: Do not add your Coca-Cola because the carbonation will make your cocktail shaker explode and it will go everywhere!
Take your small bowl of water and dip a finger into it. Now rub your wet finger around the rim of your cocktail glass. You want to lightly moisten it.
Pour some of your silver sprinkles onto a small place and then dip your cocktail glass upside down. You want to cover the rim of the glass with the silver sprinkles.
Pour your cocktail mixture into your cocktail glass being careful to not wet the side of the glass (this will cause the sugar sprinkles to dissolve).
Fill the rest of your cocktail glass with Coca-Cola and stir gently.
