MrBeast Launches Unique Peanut Butter Cup Sparkling Water with Liquid Death

When you think sparkling water, you probably think flavors like lemon, raspberry, orange and myriad other fruits and fruit combinations. While those can, of course, be absolutely delicious, and there's nothing wrong with a classic take on a fan-favorite drink, YouTube celebrity and businessman MrBeast is offering sparkling water lovers so much more than standard fare with a brand-new collaboration between his snack brand, Feastables, and better-for-you beverage company Liquid Death.

Launching today, Feastables and Liquid Death are debuting their new, limited-edition sparkling water flavor, Peanut Butter Cup. This unexpected drink is inspired by the Feastables peanut butter cup candy, and it maintains the Liquid Death brand's dedication to being a healthier alternative to traditional sodas.

Each 12 oz. can of Liquid Death x Feastables Peanut Butter Cup Flavored Sparkling Water comes in at just 10 calories and 2 grams of sugar and contains no artificial sweeteners. The brands also state that the drink is allergen-free, and it is made with no actual nuts.

The launch comes with a brand-new ad spot featuring MrBeast, in which he buys "the world's most dangerous biker bar" and introduces the guests to the peanut butter cup flavor. In addition to a high-energy jingle about the drink, the ad features the tagline for the newly-released product, "Because nothing says tough like peanut butter cup."

The limited-edition Feastables x Liquid Death flavor will be available for purchase on Amazon and will be available at participating grocery and retail stores, including 7-Eleven and Five Below, while supplies last.

This news comes on the heels of some other fun collaborations and launches from both brands this year, including Liquid Death's collaboration with Pop-Tarts on the Pop-Tarts Carnage Iced Tea , which tastes like Frosted Strawberry Pop-Tarts, and Feastables' partnership with The Super Mario Galaxy Movie , which included the rollout of the Mario Galaxy Cocoa Crunch candy bar, Mario Sour Boosts and Yoshi Eggs.
