I won a Margarita Ball so I finally researched to see what I actually won. See the attached photo.
It's described as a plastic ball jug with a pump for dispensing margaritas. The Jose Cuervo Margarita Ball Margarita Dispenser holds 7 1/2 Liters of Margaritas or other drinks. Great fun at parties. Just add your favorite Tequila and mix.
P.S. (Actually my mom in Ohio won the Margarita Ball since us Texans aren't allowed to enter!!)
