Carefully pour the lemon juice, raspberry syrup and pomegranate juice into your serving glass. (Try not to get it on the edges of the glass.)
Use a long bar spoon to mix it all together. This will be the red layer of the drink.
Fill the glass with ice.
Add in the sparkling lemonade, pouring slowly so it won't mix with the red layer.
In a separate mixing glass, add the vodka and Blue Curacao and stir them together with a clean spoon.
Pour the blue mixture onto the top of the lemonade layer, going slowly so the layers won't mix.
Optionally, sprinkle some edible glitter over top of the drink, and serve!
Notes
If you don't have raspberry syrup, you can use grenadine or another red-colored syrup. The syrup is the main flavor in the drink, so use what you like best!
If you don't have Blue Curacao, just mix a single drop of blue food coloring in with the vodka.
You can use Sprite instead of the sparkling lemonade, but mix it with some extra lemon juice before adding it to give it more of a white color (instead of clear).
