Day 55 – CESIUM.

  1. Cesium is yet another fun pyrophoric substance, capable of spontaneous combustion at the drop of a hat — and will react with water at -177F. It’s typically kept and shipped in mineral oil or argon. It was discovered by Robert Bunsen in 1860 as a means of popularizing flame tests using his namesake burner.

    It melts about 84F, which is just above room temperature. If you made a little statue out of it and left it in a windowsill, that’s not the one you’re going to get the big prize for. Its favorite Disney character is Olaf from Frozen.

  2. Even back in the day, it was noted that Group 17, the Halogens, were absolutely rabid frothing mad in row 2 (fluorine), but got to be comparatively mellow by row five (Iodine). In the case of Group 1, the alkali metals, row 2 (Lithium) was comparatively mellow, but down around row 5 were absolutely rabid frothing mad. So, let’s see — Group 1, row 5……….that’s cesium!

  3. In industry, cesium compounds are used in similar ways to fluorine compounds — when you want something nonreactive around. Because fluorine and cesium are so reactive, their compounds are both extremely stable — little can unreact after such a welcome! A major difference, of course, being that cesium provides heavy and dense nonreactive substances while fluorine provides lighter and fluffier varieties.

  4. Today’s musical interlude includes a bit of a dance number. People tend to think of vaudeville as a bunch of amateurs because there weren’t any giant stage apparatus or laser light shows…..but vaudeville toured the nation and was exceedingly competitive. There was, certainly, a lot of schlock out there, but the top acts were outstanding. Such were the Nicholas Brothers……but we’ll go with a musical number by Cab Calloway: “Jumpin’ Jive”.

    (It’s sort-of like an early Cirque du Soleil.)

  5. And, because I’m tired, I’m going to go with a very brief amusing anecdote……

    The Matterhorn Bobsleds ride opened in Disneyland on June 14, 1959. Like many things in Disneyland, it is a tremendous noisy distraction from several necessary things that were going on — e.g., the passage of the skyway between Tomorrowland and Fantasyland. The ride system was the first tubular steel roller coaster in the world — instead of riding on tracks, the cars’ wheels (which were grooved to fit the tube) were bolted on opposite sides of a tube for enhanced stability.

    The original Matterhorn mountain is a 14,692-foot peak in the Alps on the border between Italy and Switzerland. The Disneyland version, not so much. Back in the early 60s, someone was saying that the Disneyland Matterhorn was much, much shorter than the original — and the base was full of holes where the bobsleds wove in and out.

    Disney shrugged — “it’s a Swiss mountain.”

  6. Cesium is a dull gold color, one of the few metals that doesn’t look gray.

    Dumping some in water leads to a LESS violent reaction than sodium or potassium; yes even though it is more reactive chemically. It somehow reacts too fast to cause the explosions (which is hot hydrogen igniting in air, if I recall correctly).
