This is from a mod of mine which I am going public with very soon.
It is mostly a mod to add stuff to Nuclear Reactions, but has some other elements as well.

Full List of Additions:

Cobalt- Inert Metal, reacts with Neutrons and becomes Cobalt-60

Cobalt-60- Decays and releases Neutrons (Hidden because then what would be the point of Cobalt?)

Aluminum Thermite- Thermite that ignites in the same manner as the original, but much hotter. Made out of necessity for a powerful heat-based cutter without pressure. Can be made with Neutrons + Thermite or directly out of the menu.

Butane- Dark-Red Almost Invisible Gas. Ignites profusely, mostly inert (No reaction with Pressure)

Liquid Noble- A liquid form of Noble Gas.

Bismuth- A Heavy Inert Metal, currently only useful as a bridge for Polonium Creation, but will have more reactions later.

Polonium- Created by Bismuth + Neutrons, (Bismuth + Deutrons IRL, but whatever) hidden because it just shows up as Neutrons unless created by Bismuth + Neutrons

Cobalt Powder- A powder form of Cobalt, with a slightly different reaction.

Cobalt-60 Powder- Created by Cobalt Powder + Neutrons. Same effect as Cobalt-60 (Hidden as well)

Any Thoughts on the actual elements or suggestions as to what to add before I do a public release?

Argh, Wrong Title.

Oh, these aren't just ideas, these are completed particles ;)
But Thanks :D

What is this I don't even?

We have an IRC?

Epic.

Edit~ I'm on irc.freenode.net #powder
