Step 1: Add grenadine to your glass
In a tall glass filled with ice, pour 0.5 oz grenadine first. This heavy syrup will settle at the bottom, creating a beautiful layered effect.

Step 2: Mix vodka and blue curaçao
In a separate shaker or measuring cup, combine 1.5 oz vodka with 1 oz blue curaçao. Stir or shake lightly.

Step 3: Slowly layer over grenadine
Pour the vodka and curaçao mixture gently over the back of a spoon onto the grenadine layer. This helps preserve the layers and keeps the colors distinct.

Step 4: Top with Sprite
Slowly top the drink with Sprite or another lemon-lime soda. Pour gently to maintain the color gradient and give the drink a sparkling finish.

Step 5: Garnish and serve
Add a banana slice on the rim and a fresh mint sprig on top. Serve with a straw and stir if desired once served.
