    I made this for one of my friends (colored pink, so I could finally make my gay Superman) for his birthday.
    I’ll have to look at your video later, because mine didn’t really glow. A bit disappointing but tasty with orange oil flavoring.

    How come superman didn’t collapse after eating it? I don’t think this really works.
