I was gonna say the tea thing but you beat me too it.
Pines are pretty awesome.
I just thought of another, but not survival related. You can use the sap for rosin when soldering.
I made a crude soldering iron by winding a bicycle spoke around a thick copper wire and sticking the other end of spoke into the end of a dowel for a handle. I made a little stand that held it above a little alcohol burner I made with a yeast jar and a bit of cotton twine. Used pine rosin. It worked quite well.
Wow holy shit, thats creative as fuck.
Ya all the guys in various electronics forums will tell you copper is shit for a soldering tip, and maybe they are right if you're sitting there all day every day soldering. But I found it quite usable. Just have to wipe on little wire kitchen scrubber pretty much after every joint and keep it well tinned. You want the fire heating the coil too, not the tip directly.
Very cheap. It's what you do when you can not afford to pay attention.
It is as good as any of the several POS $20 - $30 irons I've had. Better in my opinion.
