----Corrections for this video----
-4:58 - I show a bunch of monomers floating around as if they aren't bound to each other. This isn't the case. It should be a few polymer chains which around bound. When we pass the glass transition temperature, most of the bonds between polymers are broken (hydrogen bonds and Van Der Waals forces) not the chemical bonds between the monomers. Also, I don't believe it's the case that there are no forces at all between the polymers, just that a lot of them aren't formed. This is again why the rate of cooling is important. It dictates how many of these inter-polymer bonds may form.

-20:35 - You can totally mount the dual duct fans, I just got mixed up. You need to mount the fans to the ducts before mounting the ducts to the universal base. I got mixed up, because it's the opposite for the single fan ducts.
