Introduce Magnesium

[decal]

I love you game physics, I think it's the core and it should be improved and enriched, so I propose magnesium.

Magnesium has a lot usage (Wikipedia is my favorite friend), Magnesium helps people to sleep. (as an example)

Magnesium has some interesting effect with CO2.

When you put magnesium inside CO2 with a heat source, you can transform into C (carbon) + O (oxygen) + MgO (Magnesium oxide).
Carbon  => You can use carbon as a construction material (with not), or what you what in fact.

Oxygen => good for us  (in fact we need O2 but ... it's a game)

Magnesium oxide => multiple things .. just take a look here: https://en.wikipedia.org/wiki/Magnesium_oxide

(Maybe because we are in game, melting magnesium oxide can transform into magnesium + oxygen)

Just a video of the reaction.
