That is awesome.. a must read.
I was drinking water(sap) from a black walnut just a few days ago.
Never thought of them as a filter...
Thanks mtnboomer!

How does one take in water "through" the piece of pine?

How would one get it "though" the wood with the pine tar and pitch in the wood?

Like sucking on a straw I guess. I've got a windbreak on the north side of my house with cedars/pines/ash..........may have to give it a try. I wouldn't want the first draw of sap out of the stick though.

I cut up a Virginia pine tree in my yard that died two years ago, and had to have gloves to handle it for the tar that was all over it.

I'll wait on your report.

This was a fresh cut piece with bark removed..only a short piece an inch or so
Then it was inserted into a plastic tubing...i would think some flexible clear stuff would work.
like what you use to clean the fish tank.
Epoxy and a hose clamp to keep water from getting between the wood and tubing.
I bet a funnel was attached to the top of the hose and water poured in.

The small piece i feel would drain quite fast.
Will try it in a couple moments.

OK so no FLOW
It has been over 25 minutes with my tubing and pine "cork" trying to flow some unsweatened tea through it.
The 1" diameter 1" long piece was cut from a pine branch and then bark removed and sanded down to a tick over 7/6" diameter , inserted into a 7/16" hose funnel on top.
NO FLOW yet.
I did sand both ends with 120grit maybe that closed up the pores.
Will try again with rough cut ends.

Maybe 1" long is too long.

jakerz posted this link in the stickied Water Thread ... I think it goes into a little bit more detail -- at least there is a pic of the gadget they made and how they did it ...

Here's a link to the actual paper that was written if you want REALLY concise info (which I do )

That link you posted looks like my setup except my wood fit really tight into some heater hose.
I am using 5/8" this round and rough cut.
And the first piece was cut from a branch that fell off the pine 4 months ago.
This time i am using a fresh one.
After 10 minutes i have 1 drop forming.

I can't imagine that even under optimal conditions this would work quickly in any sense of the word ... LOL Also, from what I gleaned from the article there is some question as to whether wood that is not "fresh" would work as well due to breaks that occur in the cell walls when wood dies and dries out ...
