Oh yes, the perfect mixture to have smashed through your skin. I suppose some of the mercury would condense on the pressure change as the bulb breaks, no idea how much it is, though.Wikipedia said:A fluorescent lamp bulb is filled with a gas containing low pressure argon (or more rarely argon-neon or sometimes even krypton) and mercury vapor. The inner surface of the bulb is coated with a fluorescent paint made of varying blends of metallic and rare-earth phosphor salts. The bulb's cathode is typically made of coiled tungsten which is coated with a mixture of barium, strontium and calcium oxides (chosen to have a relatively low thermionic emission temperature).
