1 1/2 oz of Vodka
2 oz of 7-up soda (or Sprite)
1 splash of blue curacao liqueur
1 1/2 oz of blueberry schnapps
2 oz of Cranberry Juice
Pour the vodka, the schnapps and the 7-up in a highball glass. Then add in slowly the cranberry juice. Float the blue curacao on top. If done right you'll have a nice multi-coloured drink.
