Ouuuuuchh, AP Chem? Good luck. It's a good class, you learn way more in-depth than regular Chem, but it's pretty hard. I got a B+ in it last term, and that's not to be taken lightly. And there's not a lot of organic in ap chem, so I suggest you look more into rates of reactions and equlibriums. Organic is the last unit of the year, and it's not all that long. But good luck with AP Chem. It's a good class, but only if you know what you're doing.
But anyways, on to the shooter. It is harder to do things when it's cold, I agree... adhesives won't dry, stuff breaks easier, etc. But do not be discouraged.
I figured out why my shooter CO2 puncture system hasn't been working. The needle has been bending. I may just have to go to a tank, pushing back the deadline. Oh well, at least it's basically guaranteed to work.
P.S. Not entirely related to web shooters but still fairly interesting... http://www.forbes.com/sites/alexknap...-spider-sense/
