Hey guys. I'm brand new to this site so please don't get angry at me if you don't like this suggestion.
I'm suggesting Lithium Polymer.
It would obviously be considered an explosive and will start on fire when overheated or exposed to heat. (Like lithium polymer batteries). Lithium polymer burns slowly at first, and is somewhat controllable for the first couple seconds, but quickly ignites into a very hot and large flame. Stops burning immediately when it is gone, or when there is no more to be burned. (obviously).Hope you like this suggestion and let me know what you think. This will also act as a liquid form of battery. When it is heated, it turns into noble gas. Thanks.
I was recommended to join this forum from Finalflash50. I know him in real life.
Neospector++ Name 5-10 (actually useful) applications. If you can't there's not much point because all the other elements have this many uses, or more(some have 1 or 2 EXTREMELY useful applications, like LN2).
Finalflash50 why do i have to respond to every element suggestion, i read them all and think about it, unless it is one of the stupid ones. it depends on popularity or uniqueness to get it made.
