1 (12 oz.) can cream soda, cold
1 drop Angostura bitters
1 tbsp. grenadine syrup

Pour a drop of bitters and a tablespoon of grenadine syrup in the bottom of a large glass. Add ice, 2 cubes.

Leaving enough room for foaming, pour the cold cream soda into the bottom of the glass. Surprise! The clear beverage becomes pink and foams to a big "head". Makes one serving in a tall glass.
