Ingredients: 

• 50 ml Vodka
• 25 ml Blue Curacao
• 25 ml Grenadine Syrup
• 25 ml Lemon Juice
• 150 ml Orange Juice

Instructions:

• Shake the vodka and citrus fruits in a mixer then strain into the cocktail glass.
• Slide the grenadine syrup down one side of the glass, where it will sink to the bottom.
• Slide the curacao down the other side, to lie between the vodka and grenadine syrup, and serve before the layers have a chance to mix.
