A simple yet (somewhat) time-consuming way to make the best waterproof fatwood you will ever burn! This stuff has some amazing properties, such as being waterproof and retaining its flammability while being submerged for long periods of time, being able to burn ferociously in high speed winds (30-50 mph), and being very cheap and simple to manufacture. Any questions, comments, or suggestions, leave em on the video on on Instructables, and I'd be happy to answer/respond!
GOOD AND BAD WOODS TO USE (spoiler: no wood won't work for this)
1. Look at it: can you see the grain, and/or any tubelike structures running through it?
If so, then it will work perfectly.
2. Is it soft, or does it smell like pine or evergreens?
If so, it's probably a coniferous wood, such as spruce, pine, or cedar. 2x4s are made on spruce.
3. Is it dry?
If so, it will work just fine. The drier, the better.
To sum it up, any type of wood will work just fine for this.
