How do you make sierra mist cranberry splash?

You can't make Sierra Mist Cranberry Splash because it's not a product that exists.

Sierra Mist is a lemon-lime soda, and while it's available in different flavors, Cranberry Splash isn't one of them.

If you're looking for a cranberry-flavored soda, there are a few options:

* Cranberry sodas: Many brands offer cranberry sodas, like Schweppes, Canada Dry, and Ocean Spray.

* Cranberry-flavored sparkling water: Brands like La Croix and Perrier offer cranberry-flavored sparkling water.

* Make your own: You could easily make a cranberry soda at home by mixing cranberry juice with club soda or sparkling water.
