In a small microwave-safe bowl, combine the water and sugar. Microwave on high for about 30 seconds. Stir until the sugar is completely dissolved. Add the coconut extract and blue food coloring and stir well. This is your syrup base.
Fill a hurricane glass with crushed ice or ice cubes and add the blue syrup.
Pour your can of Sprite (or 7UP) into the glass. Top with a cherry and serve with a straw.
