What is a purple cow float?

A purple cow float is a type of beverage that is typically made with vanilla ice cream, grape soda, and a liquid sweetener like simple syrup. It is often served in a tall glass with a straw and can be topped with whipped cream and a cherry.

The name "purple cow" refers to a famous poem by Gelett Burgess, which describes a cow that is "purple and spotted" and catches people's attention. The drink is similarly eye-catching and unique due to its bright purple color.

Some variations of the purple cow float may include different flavors of soda or ice cream, or may be made with non-dairy alternatives such as soy milk or almond milk. It is a fun and festive beverage that is often served at parties or special events.
