Cherry limeade slush (thing)

This is one of the more popular fountain drinks available at Sonic Drive-in. Similar to a Shirley Temple (or at least a cheap Shirley Temple knockoff), the drink is Sprite-based, with lime juice and cherry syrup, served in a large styrofoam cup with a cherry, a slice of lime, and lots of crushed ice. Here's a suggested recipe for making your own:

• 12 oz. of Sprite (I've been told lemon-lime Slice makes it even better)(I've also been told Lemon-lime Slice is known as Sierra Mist in some markets.)
• 1/4 cup cherry syrup, (or cherry juice, or grenadine if you're into that)
• 1/4 lime
• 1 Maraschino cherry, with stem intact
• 1 large cup, full of ice

1. Pour cherry syrup into cup of ice.
2. Squeeze the lime slice gently over ice, and drop it in.
3. Add the Sprite
4. Add the cherry
   
5. Share and enjoy. Drink with a large straw. Beware of giving yourself brainfreeze. See if you can figure out how to tie a cherry stem in a knot with your tongue.
