@black6_ I mean yea, in practice its not really doable in any reasonable way... but with enough money and sterile base materials it should be possible... you would need pure (no bacteria) water and CO2 and a sterile place probably a few chemicals, and it could be done :)

Reminds me of that time NileRed made the most chemically pure cookie ever made, evne the fat was synthasized. He said it was absolutely disgusting.
