ELI5: How can my nose produce mucus at such an alarming rate when I have a cold?

It seems almost impossible that my nose could produce so much mucus in such a short amount of time.

Nobody has bothered to answer this, so here goes:  
Mucus is made in your body by combining a type of protein called mucin with water. Mucin will combine with water to form mucus roughly twenty times the volume of the original protein, that means you don't need much mucin to make a lot of mucus you just need water (which your body has lots of).
