NileRed attempts to replicate a scientific paper on densifying wood to make it bulletproof. After experimenting with chemical treatments, pressing pressures, and multiple wood layers, he finally successfully stops a .22 LR bullet with a three-layer densified pine block.

Answers: Can you make bulletproof wood at home?
- densified wood
- bulletproof wood manufacturing
- wood delignification
- hot pressing wood
- ballistic testing of wood
What it concludes
- Treating wood with sodium hydroxide and sodium sulfite removes lignin and hemicellulose, leaving loose cellulose that can be squished.
- A single layer of densified wood is unable to stop a pellet gun or a .22 LR bullet, but a three-layer cross-stacked version successfully stops a .22 LR bullet.
- Stacking multiple layers of densified wood with grain directions at 90 degrees to each other significantly increases its strength.
