From my experience shooting plywood, the 9mm would have no problem going through the same thickness. He is legitimately on to something with his process.
A 9mm would get through 45 centimetres of plywood???

#22"Computer Shopper" magazines made for great backstops when zeroing scopes in a .22lr rifle. I suspect layering paper with a squishy resin in multiple layers would be very effective armor. Is paper close enough to call it "from wood"?
Layering paper and resin makes a material called “Micarta” which has been around for awhile.

#23I hate to rain on his parade, but as a bulletproof material that stuff is effectively worthless. An equal density of plain transparent polycarbonate has substantially more ballistic resistance, and is far easier to make and mold to shape. The same can be said for equal densities of steel, aluminum, magnesium, titanium, etc.
However... As a material for musical instrument construction, that hyper-densified wood might be very interesting.
Re: Making Bulletproof Wood [video]
#24Another curious material if ballistic protection is your fancy, is fiber reinforced closed cell foamed concrete at a proper density and thickness. While not suitable as personal armor due to thickness (generally around 1.5ft/45cm), it’s something can provide rapid and cheap local access to protection from shrapnel and rifle bullets, which unfortunately is still a genuine concern around the world. At lower density foa…
my back of the napkin math only puts this around the same stopping power as plywood of similar thickness. Sand bags work a lot better and are a hell of a lot easier and cheaper to produce
Would a wet sandbag have more stopping power than a dry one? Or does that reduce the sheering strength?

that appears to be pressure injecting resin so it blends with fibers and makes a solid. Early reinforced bakelite.
I'm thinking layers of interleaved paper and a resin. Free to move internally, slightly; with some fluidity remaining in the goo. It'd need a hard shell layer too but im thinking "spiderweb" shock resilience might come from the fluid component.
like Air between the pages of the magazines.

#26Regarding the interior of the wood not being soaked by the stuff when it was cut open. (35:32) I suspect moisture content of the wood is a factor. A similar challenge is faced when cooking French toast, with particularly thick slices of bread. When making French toast, you want the custard to fully soak the bread, but a similar effect occurs if you use moist bread, where the middle is not soaked as well as the outside, it looks almost exactly like that cross section of the wood in the video. The solution is to leave the sliced bread out overnight, to allow the moisture that is filling all the capillary fibers to dry out. Then you can make perfect French toast because the dry capillary fibers are much better at sucking the custard in to the center, like a bazillion little straws.
Thus, I suspect drying the wood ahead of time would help?
P.S.: on the thickly sliced French toast, to get it cooked evenly inside with a nice exterior crust, after custard saturation (don't overdo it) I recommend searing the slices quickly in a pan with butter, then throwing in an oven at 350degF for 3-4 minutes. My custard recipe per serving is approximately 1 cup dairy, 1 egg, 1 tablespoon of honey, and a little pinch of salt. Briefly zap the honey in microwave to make it easier to mix.

#27YouTube has been pushing me this video all day. I guess we’re all in the same “hacker” algorithm bubble
This channel is one of the "positive outliers", since it's gained popularity amongst many people worldwide even outside of science minded people

Thanks for explaining that! I didn't know why I was having the problem, even after soaking the bread in custard for a long time!

Water is very effective at stopping bullets, so I would assume so.

are you using the whole egg or just the yolk for the custard?
