Firecracker Drink: 1 oz. Vodka, 1 oz. Lemon Juice, 1 oz. Blue Curaao, oz. Grenadine, Splash of Simple Syrup. To make simple syrup, mix equal parts hot water and sugar until sugar is dissolved. Pour grenadine into bottom of an empty Collins glass. Add ice. Gently pour curaao over grenadine. In a cocktail shaker filled with ice, combine vodka, lemon juice, and simple syrup. Strain over curacao and serve with straw on the side, so guests can place straw into glass and see the layers explode.
