More from the element of the day series, Lanthanum. Really the whole reason to watch this one is to listen to the mnemonic, quite amusing according to him. “Language centers praise notes small promise of small European garden tubs dinosaurs hobble erotically thrumming yellow lutes.” What the hell? Maybe you should just memorize all of the elements, it sounds easier than trying to remember this little nursery rhyme. Anyway, watch and enjoy.
