Some assorted gasses to tinker with

[CalliopeSoups]

Now we have constructable atmos pipes I think it'd be fun to have some more gasses to fool around with in mechcomp. Not really suggesting this from a toxins perspective where you'd be crafting actual useful stuff in the lab, but rather one off joke gasses like farts.

A few ideas:

• Void gas, pumped from the void azone. I dunno what this could do I just thought void gas was cool.
  
• Gaseous botany plant, maybe a stink plant that makes you vomit? Make it vanish on contact with lavender or somethin. (Blender grav trap mixed with this to make a makeshift janitor tc item)
  
• Foods that change your farts into a different gas.
  
• Gas version of helium, so you can charge for helium shots or sneakily release it into medbay for the funny. Equivalent deep voice version would also be funny.
  
• Balding gas. Possibly too funny.
