Just in case anyone genuinely doesn't know, the warhammer is a wooden mallet, useful for persuading things into place in woodworking, and for hitting chisels. And the caltrops are paint stands, used to raise something that needs painting/varnishing up off the floor so you can run the brush all the way down to the bottom edge, wipe off any drips that form at the bottom edge, and just generally make painting easier for you.
Permeability is the measurement of porosity. Original Comment is about smoke passing through the block due to the open space in the block (porosity). The amount of smoke passing through would be a rating of permiabilty. Point being you’re talking about the same thing in different contexts.
Pumice stone = highly porous, very low permeability. Permeability in porous solids is a function of pore throat radius and connectivity. Sauce: 13 years working as a petrophysicist
While gluing a wooden plug into a red oak stair post I saw a puff of sawdust out the top of it when I tapped the plug in. About 8 inches of travel through the grain.
Wood is basically a bunch of straws smooshed together. Xylem is the water conducting tissue and is dead at maturity. The living part of the tree is the bark, the wood is dead and functions as a support and conducting material. There's usually a continuous flow of water from the roots out of the leaves when it's warm and wet. Plants can get embolisms when a pocket of air gets trapped in the Xylem. That's why you have to cut the bottom 3" off of flowers before putting them in water.
This, SO MUCH. My question is when does the tree truly "die"? As death is part of its life cycle, death is integral to survival, and even after the leaves fall off and the bark dies, it joins its progeny in their growth. I figure death is an abstract concept made out of a human need to give order and finality to allow our limited understanding of a greater concept of existence. We die and no longer provide, side from our biomass, so we are buried, which is the only part that makes sense.
That's such a tough question when it comes to plants because they naturally clone themselves. An individual may no longer live but if it has 1000 plants that were once a part of it, is it dead? It's a ship of Theseus kind of thing. Some plants live through one reproductive cycle, some plants live through thousands. Plants are so different from humans that studying them is like studying aliens from another planet. Much of how we view the world is limited by our own experiences.
We have a very limited idea of what intelligence is and so many scientists now support the thought that plants make decisions. We know for a fact they can recognize kin, friendly plants, predators and so on. They see more colors than we can. They have an excellent sense of smell, can hear running water, they know which way is up, they can sense touch and temperature, CO2 concentration, and can "taste" what's in soil and grow towards our away from it.
Funny you should say that. Just saw a post about Holly trees that can change their leaf structure from smooth to pointy if they get nibbled on by deer and whatnot. The crown of the tree will actually have smooth leaves while the reachable ones will be spiked. People sometimes forget the trees and especially fungi have had A LOT more time to evolve than animals.

This seems like a perfect habitat for bacteria or mold

That’s a pretty neat visualization!

If I soaked my logs in wood would you still love me?

Red Oak has capillaries throughout. It rots fast when outside. White Oak does not so it lasts longer.
QueefMalone
How soaked are we talkin' here?
inthepines
Capillary action?

You can blow bubbles through a piece of red oak in water

Whatcha makin?

Home Depot wood I presume.

It's always a good time to get your wood wet. 😉

I think your mallet it full.

how is wood a liquid?

How to tell the different between red oak and white oak....

A warhammer and caltrops? What's happening in that room?

Love 'soak logs in wood'--lolling thinking @ whoever is OP, good job and Long Live the Meme!

Ohhhh I didn’t even know- we ought to be ashamed of ourselves; as a Jungle Man, this is facts we NEED to know: will inquire further research:

Wood grain is like bunches of tiny straws. This wood is thirsty.

Capillary action. Mobius effect.

Teacher at trade school for cabinetmaking blew smoke through a piece of oak to demonstrate the porousness (sp?) of it. Was pretty cool.

Porosity is the word you're looking for
lpooptoomuch
no porosity is void spaces in a material and permeability is the ability of a material to transmit fluids.

Pretty surprised it's still so porous even after being worked.

This is why cutting boards aren't made from oak.

jea could red oak it has pretty big "channels" sadly the reason you can't build Wine or Whisky barrels out of it.

those angels be thirsty af in those barrels

Dont know what would be more impactful, the angels share or the devil's cut.

A whole 8 inches of wood you say?
