3. Liquid Metal Superhero

Imagine a liquid metal superhero, softer than a newborn's cheek, and able to illuminate the darkest corners of Gotham with its hypnotic blue glow; enter, Cesium: Discovered in 1860, this extraordinarily rare element, constituting only 3 grams out of every 1,000 kilograms of Earth's crust, has the unique distinction of being the softest metal known, easily cut with a butter knife, and emits a captivating blue light when exposed to flame or electricity, all thanks to its lone valence electron.

4. Party Animal of the Periodic Table

You might say cesium is the ultimate party animal of the periodic table: it's always in a liquid state when it's warm and loves to put on a fantastic blue light show! In fact, cesium has a melting point of just 28.4°C (83.1°F), making it one of the few elements that turn liquid at or below room temperature. Even better, when it's heated beyond that, cesium emits a dazzling blue color that's widely used to spark up fireworks and other explosive pyrotechnics.

7. Ice-Breaking Smooth Talker

If cesium were a guest at a party, it'd be the ice-breaking smooth talker that never needs to warm up: this rare metal is already a liquid near room temperature! Sharing the exclusive club with gallium and mercury, cesium's fascinating state allows it to cool things down in high-temperature situations, like in nuclear reactors.

9. Elusive Party Crasher

Oh, cesium, you elusive party crasher: you're rarely found, but when you show up, things get catalytic! In an exclusive club of two, Canada and Zimbabwe are the bouncers protecting this precious element, while cesium compounds sneak into the manufacturing scene as catalysts for urethane and sulfuric acid production. Not to mention, cesium graphite is the environmental superhero we didn’t know we needed, swooping in to remove radioactive traces from sodium-cooled reactors.
