MORE CREATIONS FROM XCVG's GARAGE!
I built a soda can stove. Unfortunately, I kind of screwed up the holes and I can't get it to light. You have to heat it up- I dumped some fuel under it and lit it up. It did light just before the fuel below all burned up, then went out. I used 70% isopropyl because that's all I have.
So, later I'll try again, maybe build one with properly spaced holes.
EDIT: Achieved ignition and a self-sustaining flame, but had to heat the Heck out of it to do so. Useless for actual backpacking or similar use, and barely usable for a burning-stuff-burner. Will try again... tomorrow.
