Soda (preferably any type of clear soda; you can even use ginger ale if you wish)
Jar of Maraschino Cherries
Ice Cubes (optional)
Place ice cubes into a drinking cup.
Pour the soda in the cup. Wait until it finishes fizzing before you do the next step.
Open the jar of maraschino cherries and place some of the syrup in the soda. You can also add cherries if you wish. The amount of syrup you place in is your choice.
