Editing Ice cream float (section)

===Purple cow===
In the context of ice cream soda, a purple cow is vanilla ice cream in purple grape soda. The Purple Cow,<ref>[http://www.purplecowlr.com/ The Purple Cow]</ref> a restaurant chain in the southern United States, features this and similar beverages. In a more general context, a purple cow may refer to a non-carbonated grape juice and vanilla ice cream combination. [[Grapico]], a brand of grape soda bottled in [[Birmingham, Alabama]], is ubiquitously linked to ice cream floats in that state.

The soda is named after [[Gelett Burgess]]'s 1895 nonsense poem [[Purple Cow]].
