Start by rimming your glasses with lime juice and then dip them into green sugar.

In a shaker, combine the vodka, blue curaçao, lemon-lime soda, and cranberry juice.

Fill the shaker with ice and shake well for about 15 seconds.

Using a strainer, pour the cocktail mixture into the prepared glasses.

Add a lime wedge to each glass for garnish.

Serve the cocktails right away to enjoy the fizz.

If making for a crowd, multiply the ingredients and mix in a large pitcher, adding soda just before serving.
