FRESH 12oz glass bottles Radioactive Mulberry soda!! Take your taste buds on a ride that is out of this world! Radioactive Mulberry is a tonic water-based drink with a subtle fruit flavor punctuated by a strong after-bite only martians could’ve brewed up. Pop the top and let it chill awhile for a smoother taste with less bite. While this is a funny, novelty soda, trust us when we tell you it is not something you would drink very often…Soda glows in the dark under a black light – avoid exposing it to UV rays for best results.
