Fill a glass with ice.

Pour 1 oz of Grenadine into the glass as the bottom layer.

In a shaker filled with ice, combine 1 oz of Lime Juice, 1 oz of Vodka, and 1 oz of Simple Syrup. Shake well.

Using a strainer, slowly pour the lime juice, vodka, and simple syrup mixture over the grenadine layer in the glass, using the back of a spoon to help pour slowly.

Once the second layer is added, slowly pour Blue Curacao over the back of the spoon to create the top layer.

Garnish the glass with a slice of lime.

Add a fun straw if desired and enjoy!
