When pounded into a tree, a stream of fresh water flows from the tube. The technique used in the movie would only work in early spring or late winter, when the watery sap runs high in the trees. The taps that are placed in maple trees are placed into drilled holes and the resultant fluid is sap, not water.
Sycamore trees (Platanus occidentalis), birches (the genus Betula), and hickories (the genus Carya) can also be tapped for drinking water that can be boiled for syrup. Black birch sap is particularly delicious.
What happens if you find yourself lost in the woods with no potable water?
The clock starts ticking, that’s what. You can only live three days without water, after that you’re buzzard food. Tick. Tock.
Finding emergency drinking water should be your top priority in that situation, but sometimes you’re not lucky enough to have any groundwater nearby. So, what then?
One primitive survival tactic that you can implement quickly using only the most basic of survival tools is harvesting emergency drinking water from the very trees all around you.
The best part is you don’t have to filter or boil this water, the tree does all the cleaning for you. And this isn’t just regular water either, it contains all the good stuff the tree is using to feed itself – minor nutrients, minerals, vitamins, and sugars.
This is a pretty nice video from Rob at Sigma 3 Survival school that illustrates how to fairly easily get water from a tree. This could come in handy in a survival situation but according to the narrator is only effective 2 times a year (early spring and late winter) and works better with certain trees.
Rob also demonstrates how to use a root from the tree to support your canteen while the water flows into it.
If your tree is leaking water from the trunk,, there is a good chance your tree has bacterial disease called wetwood, also known as slime flux. This disease enters and seeps out of the trees in a liquid form that looks like water. It’s not usually a little liquid either.
Affected trees may leak copious amounts of liquid out of their trunks or branches, discoloring the bark and dripping onto the surrounding ground. Bacterial wetwood occurs as after bacteria infect the wood of a tree. Bacteria can enter the wood through any wound in a trunk, limb or root.
