That's true. Although I'm unclear on how does dissolving it in a solvent make it rapidly un-dissolve (I'm not sure what the correct term is) when it comes out. Please explain?

nitrogen

Oxygen is definitely the best choice. We can mix it with the carbon and/or nitrogen to get ourselves a good polymer, probably mix it with C2H4 (urethane, right?).

But, this is discussion for the formula thread.
That makes sense, but three things:

1. How does one get such chemicals?
2. Does this including the "sticking" portion of the webs?
3. I believe that's Ethylene, but I'm not sure.

We probably should go to the formula topic. I found a link so we can talk about this there.
