Collecting Water by Condensation


A very simple way to collect fresh purified water in the wilderness is to tie a plastic bag around a tree branch. First, find a green, leafy branch that has good sun exposure and tie a large plastic bag tightly around it so that no air escapes. Place a small stone in one of the corners of the bag so the water that has evaporated from the tree leafs throughout the day will all drip down to one point. At the end of the day tear a small hole in the corner to collect the water and filter it through a piece of cloth such as a bandana to remove any debris. Simply tie up the corner and you can repeat this process for up to 3 days on the same branch. Happy Surviving!

  5. Thanks for coming to my blog. Please come back anytime. You remind me of my oldest son. He used to do lots of back country hiking --and even took an Alaska hike one year by himself. He doesn't do it now (he's 48 now)---but he loved it when he did it. Hubby and I love to hike and be out in nature also.

    Thanks again--and hope to see you again.

  8. I've read this in a book before except for the 3 days max tip. I thought you could continue indefinitely unless the tree was dead.

  13. I'm reminded of a little project we did with the kids at science camp: placing a ziploc baggie around a small leafy of piney branch of a tree and checking it the next day for water. Pretty neat.

    Thanks, and thanks for visiting.
    Cheers.

  21. Unique Outdoor Survival Skills

    Don't you find it ironic that even with all this scandalously expensive education, people today know so little?

    If they can't even fix their car, how are they supposed to handle a - let's say - long term food shortage?

    You can't possibly hope they'd know how to garden and produce their own food, save seeds for next year, and use leaves plowed under to fertilize the soil.

    Not to mention trapping, catching, skinning and cooking a rabbit...

    These may seem advanced outdoor survival skills now, but back in the days, they were merely called "Living".

    Watch this short video now and discover a set of unique and fantastic survival skills used and perfected by our ancestors.

    Don't wait for the next crisis to hit and live to regret you had the chance to learn these skills but didn't.

    Thanks again.
