Color:Light Brown
Apprevation: [FRAN]
Melting Point: 300K
Uses: Used in aerospace rockets and the uses, are limitless reacts to saltwater and calm when contained in a glass jar, and when distarbed it lights up bluish. Could be used in Salt Water Bombs and Rockets this element is so sensitive.
Francium is very sensitive except it just reacts to saltwater and pressure but, you could use wall and glass to contain it. @therocketeer i dunno lol.
Not only that, but francium's 20 minute half-life means that it would explosively evaporate from the heat generated by its own radioactivity.
Use it as a time delay fuse?
