1 Dig two crater-shaped depressions concentrically on a slightly sloping slope, one bigger, and the other smaller. The recesses should be separated by the earth shaft.
2 Place a tent made of a plastic bag over the recesses; Lift the top with a stick on the mast, and crush the bottom with stones. Line the cavity with green leaves and grass.
3 After making a mound of leaves, tie the end of the bag tight, paying attention, so that the foil does not touch the plants. When the leaves start to sweat, the water vapor will settle on the sides of the tent and condense, and then it flows into the channel between the craters. When in the bottom, a lot of water will collect in the extended part of the canal, you can carefully loosen the string at the end of the bag and place the dish under it.
In exceptional situations, you can collect water droplets scattered in the fog floating above wetlands, by laying a sheet of fabric on the ground or spreading it between trees. Another way is to stretch a piece of plastic wrap over the grass overnight. When the air cools down at night, the water vapor beneath it will start to condense. It is true that no more water can be obtained this way, but at least for a while it will quench your thirst.
Water from the twig
Place a plastic bag over a fresh twig with green leaves and tie the end of it. The water vapor released by the leaves will start to settle on the inside of the bag and condense.
