Have you ever wondered how to purify water with a tree branch?
Off Grid Quest states:
In a paper published this week in the journal PLoS ONE, the researchers demonstrate that a small piece of sapwood (the youngest wood of a tree which serves to move water up from the roots) can filter out more than 99 percent of the bacteria E. coli from water. They say the size of the pores in sapwood -- which contains xylem tissue evolved to transport sap up the length of a tree -- also allows water through while blocking most types of bacteria.
So what does this mean for us in an emergency situation? Here is where it gets interesting! We can use those scientific finds to purify our water!
"To study sapwood's water-filtering potential, the researchers collected branches of white pine and stripped off the outer bark. They cut small sections of sapwood measuring about an inch long and half an inch wide, and mounted each in plastic tubing, sealed with epoxy and secured with clamps."
The experiment showed that you are able to purify water with a tree branch. This is a neat idea that can be implemented in an emergency situation with little work and can save your life.
So if you find yourself in a wilderness survival situation, use the above information to save your life and filter that water before you drink it. This fun fact is brought to you by the world of science.
