Mendeleev's virtual table

If in childhood you liked to mix iodine crystals with liquid ammonia and to put this substance (iodide nitrogen) on fences, to arrange big badabum to idly walking cats, to pour phenolphthalein in schoolmates soups in school dining room or maybe you asked ice-cream sellers for dry ice to push it in a plastic bottle ( some call this unique device "torpedo") and threw under the bottom of nearest car to make it explode, then you are true chemist. And you, of course, need Mendeleev's virtual table, in which besides of standard information on chemical elements, it is collected some additional data. Simply direct the cursor at any hydrogen, helium or uranium and receive the most detailed information. Very useful and unique site.
