Forget bringing soda to your next tailgate party. Now you can show up ready to party by announcing "I've got Bawls." The people at ThinkGeek.com call Bawls  their favorite caffeinated beverage, and it's a popular choice for many of their customers as well. The caffeine (80mgs in each 10 ounce distinctly colored cobalt-blue bottle) is derived from the Guarana berry from the Amazon. This berry lends a sweet flavor to the drink. And the taste ?  It's described as being somewhat like a shirley temple or even more like a fruity Sprite. The only way to experience Bawls is to get a case and figure it out for yourselves.
