Mash 1 tbsp of blueberries and combine with sugar. Swirl the rim through the blueberry/sugar mixture.
Add ice to the sugar-rimmed glass and add in 1 tbsp of blueberries and 1 tsp of fresh mint. Pour in blueberry lemonade, vodka, and simple syrup. Top with sparkling mineral water and stir.
For a cool effect, add one small drop of all-natural blue food coloring (do not stir), and a Halloween decoration on top!
