Copper tubing in DIY CO2

Can you explain more, please? I was talking about copper tubing in the
rubber stopper of a bottle containing the yeast solution. One then runs a
plastic airline from the copper tube into the tank. Of course, one can use
some other metal; plastic isn't as rigid and much harder to insert snugly
into a rubber stopper.

I can understand acidity's effect on  copper but how would the copper get
carried by CO2 gas through airline tubing into the tank?
