This looks like a fun DIY experiment for your next camping trip. All you need is a drill, 1″ bit and length of firewood. The video above does a good job of explaining the process, but to summarize:
- Cut a 14″ piece of firewood.
- Drill down into firewood with a 1″ drill bit.
- Drill an intersecting hole in the middle of the firewood.
- Place small rocks on top of log (or pound in nails) to hold a pot above the hole.
- Ignite!
