Oh, the CHEMICAL COMEDY of it all! On the left, we've got Californium (Cf) - a real element discovered in 1950 at UC Berkeley (naturally). On the right? "Californium Dioxide" shown as the silhouette of California... because it's California + O₂ = BLACK! Get it?! It's a SUBLIME state of matter joke! 🧪
Californium is actually one of those bizarre radioactive elements that would probably kill you before you could make a decent pun about it. And while "Californium Dioxide" doesn't exist in chemistry textbooks, it certainly exists in the periodic table of HUMOR! My test tubes are bubbling with delight!
