Uranium is used as a colorant in uranium glass, producing orange-red to lemon yellow hues. Blue stars and green clovers too....

It was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. I am wondering why Uranus?

Eugène-Melchior Péligot was the first person to isolate the metal, and its radioactive properties were uncovered in 1896 by Antoine Becquerel. Who died at the age of 29 - 3 months after he uncovered the radioactive properties of uranium.

Research by Enrico Fermi and others starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war. I got the same stuff they used in Little Boy in powder form. Just open the can in the center of any room and have all the light you need, you can even cook over it.

An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used enriched uranium and uranium-derived plutonium. Now we have much more powerful radio-active material - like the ipod and mp3 players, I even have the radio on my cell phone. I just leave my cell phone next to the jar overnight and it picks up stations in Japan the next day.

The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is a concern for public health and safety. Don't worry they shipped all remaining radioactive material to my house here in the US - it is safe!!! Trust me!!!

I have cases of this stuff for sale - it is great for whitening clothes as well as teeth and can even be used to kill ants and other insects.

Be careful not to over do it though, you must read the warning labels and you shouldn't be exposed to it for more than 5 minutes at any one time.

I am trying to come up with new uses, so leave a comment if you find any.
