Cherry Slushee

Pour 1 cup of the club soda into a blender. Add the sugar, Kool-Aid mix, and cherry extract. Blend this until all of the sugar is dissolved. Add the crushed ice and blend on high speed until the drink is a slushy, smooth consistency, with no remaining chunks of ice. Add the remaining club soda and blend briefly until mixed. You may have to stop the blender and use a long spoon to stir up the contents. If necessary, put the blender into your freezer for 1/2 hour. This will thicken it. After 1/2 hour remove blender from freezer and, again, blend briefly to mix.
