This is a Francium Lab test in which they exploded it!
There are no common uses for francium because of how radio-active it is. Scientist estimate that there is no more than an ounce of francium on earth at a time on the Earth's crust.
Francium History:

Francium was discovered in 1939 by Marguerite Perey of the Curie Institute in Paris. But Francium's was predicted by Mendeleev in the 1870's.

Marguerite Perey noticed a decay from a sample of actinium. Francium is the longest living isotope of actinum with a half-life of 22min. She later named Francium by her home country France

Francium Isolation:

Francium is a very rare element it is only found in some traces of uranium minerals. It has never been isolated as the pure element. Francium is also a highly radioactive, any amount of Francium would decompose to other elements

Francium is the longest lived isotope of Actinium. It has a half life of 22 min.

Reaction of Francium with the Air

No onn so far has ever esembled enough Francium in one place to know its exact physical property. Some scientist believe that Francium could be a very soft material, easily cut, solid meatal or even a liquid. A fresh piece of Francium would quickly tarnish because of the reaction with oxogyn.

Facts of Francium

-Francium was discovered in France in 1939 by Marguerite Derey.

-It's obtained from decay of Actinium.

-No one knows for sure but people believe it to be a metalic color and to have cubic structure.
