I tried observing the afterglow on peanut butter using my UV pen. It's fainter than what I saw on your video, but it lasted a couple of seconds longer at room temperature. I wouldn't ever guessed my peanut butter could do that. Science is truly awesome!

That's amazing. I once happened to have a peanut butter sandwich under blacklight, but it never occurred to me that there might be an afterglow.
