A little chemistry anyone? Here's everything you never wanted to know about iodine. But it's not as dreadful as you'd think. Iodine and its compounds disinfect surgical sites, seed clouds, and can protect you from certain nuclear fallout. And it's great for blowing up stuff, too! And there's a quiz with a very special prize for the winner!
Time for another hideous chemistry lesson. No one requested a tutorial on this interesting metal. But guess what -- you got one anyhow! Palladium, named after a Greek goddess and worth more than gold, also keeps our air clean. There's plenty of interesting stuff you'll learn here (if you can stand to read this).
