'Phosphorescent' is a fancy word we use to talk about things that glow in the dark without needing any light. For example, some jellyfish or minerals can look like they're still glowing even when there's no light around. We can also use the word to describe things that hold on to a glow after being exposed to light, like a cool sticker that you stick on your wall and it glows in the dark after you've shone a torch on it. So, 'phosphorescent' is a word we use to describe things that shine like a lightbulb, but without any electricity or candlelight - pretty cool, right?
