Didn't work:
branch cut my pocket chainsaw in half
strike anywhere matches (the old kind) didn't
cheap "waterproof" containers aren't
cyalumes sometimes "lume", sometimes not.
Does work: simple stuff
canteen and cup
REI stormproof matches
Katadyne MicroPure tablets
AMK heatsheets and to a much lesser extent, the thin mylar WalMart space blankets do work. But you have to remember that convective and conductive heat transfer works better than radiative heat transfer. All a heat sheet does is reflect radiated heat back, so you don't even get 100% of the heat back. If you're trying to use this in an exposed spot on the ground it won't work. The ground will conduct heat through the heat sheet touching you, and wind will convectively cool the heat sheet, while the heat sheet is conducting it away where it touches you. Now, if you insulate yourself from conduction and convection, they will work. Either use it inside your car, or on top of a thick pile of leaves/conifer needles, with a bunch piled on top, etc. Also, IMO, figure on throwing it out after one use, even the AMKs. Might not work as well as wool or polypro, but wool blankets don't fit in a small PSK pouch, either.
As for the duct tape FAK, that can be a bad idea. The adhesive in duct tape gives some people's skin a real BAD reaction. I bring 2" surgical tape (just as strong, not as harsh on skin), a couple of rolls of gauze and some triple antibiotic ointment. You can cut the tape and gauze to make a band aid (BTW am I the only one to whom Band-Aids WILL NOT stick to for very long? Even around the house I don't use them).
