How to create water from fine air

You don’t have to be a Houdini to make water from air. You just need to know how to make condensation work for you. And because water is critical to survival, these tricks are worth taking the time to learn.

Make the plants condense the water for you

This technique will not provide all the water you need to survive, but it will certainly extend the time you can survive until help arrives. Generally people can live three days without water, but if you are on an island, for example, the sun and wind will dry you out faster than if you were in a cool cave. That said, if you are stranded without water but surrounded by trees or bushes and have some plastic bags, you can get the trees to give you some of their water.

Trees draw water from underground depths, deeper than you could possibly dig, and they expired some of that water through their leaves. If you place a plastic bag on a small branch, you can actually collect water droplets when the tree exhales the water. Each 30 cm (30 cm) square plastic bag will provide you with one to two tablespoons of water a day. Since one liter equals 68 tablespoons and you need about five liters a day, that means you would need about 200 bags to stay well hydrated. It’s definitely more plastic bags than a person would normally carry, but when no other water is available, even a tablespoon is welcome.

Make a solar alembic

This will work anywhere, but if you are in a place where the days are hot and the nights are cold, it will work even better. Each solar still you make can generate around half a liter of water a day, so if you don’t have another water source, that means you’ll have to make eight to twelve of these stills to get to four to six liters of water. a day you need. they are usually necessary in survival situations.

One way to have so much plastic on hand is to carry ten large garbage bags in your backpack. Trash bags can be incredibly useful outdoors. They can be a poncho, a sleeping bag, a tent print, a sign, a trap, and a water catchment system. Oh yeah, and a garbage bag. That’s pretty handy for less than an ounce of weight for each bag. For solar stills, you want a plastic bag sheet (cut the bag in two sides to create an extra-large plastic sheet) that is about 36 inches square. If one side of the plastic is less smooth, lay it down. The extra surface makes the difference.

To make the alembic, dig a shallow hole 18 inches deep and 36 inches wide. Place a skillet in the center of the hole. If you don’t have a skillet, you can also make a skillet out of a plastic sheet that covers an excavated part of the bottom of the hole. Weigh the top plastic sheet on the edges with stones and then very, very carefully drop a large stone in the center of the plastic sheet to create a low point. Your plate should be below the low point, so you can collect the water droplets as they condense and roll down the sheet.

One of the best things about a solar still is that it can use semi-polluted water. That’s because the water you will drink has evaporated and condensed, purifying itself. If you are at the beach, you can even place a still in the high sand and distill the salt water into drinking water.
