In the Red Bull Strawberry Slush, what ingredient is added as a garnish?

The Red Bull Strawberry Slush is garnished with a cherry, which adds a pop of color and a touch of sweetness that complements the drink's flavors. Garnishes enhance the visual appeal and can also contribute to the overall experience by providing a contrasting flavor or texture. In this case, the cherry not only makes the drink look more inviting but also ties in with the fruity profile of the strawberry slush.

Other choices, while creative and enjoyable in their own right, do not typically pair with this specific drink as a garnish. Gummy worms might be fun in a more playful cocktail, a lime wedge usually accompanies drinks with a tart element, and a flashing ice cube is often used for effect rather than as a traditional garnish. Therefore, the cherry is the most fitting choice for enhancing the Red Bull Strawberry Slush.
