Adventure must learn skills in the wild: how to safe water for food

1. Wild Water

In the summer of 1980, the famous scientist Peng Jiamu disappeared while drowning in the Lop Nur area of ​​Xinjiang.

We know that life cannot be separated from water. All living things depend on water. All living things will have water. Without food, normal people can generally survive for about 20 days, but if there is no water, they cannot live for three days. It is best to use mobile water sources when looking for water sources. Here are some of the methods of drowning in the wild:

(1) Island Surabaya

On the side of the island's windward slope, there is often water and food; fresh water can also be found in the rocky caves; when digging the coast for “wells” to draw water, the puddles should be dug in a safe area above the tide signs, and their depth should enable water to be pooled. At the bottom of the pit. To remove the surface water, use the above water after settling, and of course it will be safer after boiling.

(2) Plant water intake

Many of the plant's green nuts can quickly quench thirst due to pickle, yellowish bamboo stems, coastal shrubs, and tender plants 15 to 20 cm high.

(3) Animal water intake

Moisture accounts for 50% to 80% of fish's body weight. As long as 3kg of fish are taken every day, it can meet the daily needs of an adult for freshwater. The method is to cut the fish into small pieces, or use a knife to draw cross-cuts on the back of the fish, and then squeeze out the water; or remove the big fish viscera and drink the fish juice.

(4) Condensation Water

If drifting on the sea, you can prop up an “awning” on the boat so that the water vapor in the air will rise to the top of the awning. After cooling, the water will flow into the bottom of the boat and be collected for emergencies; Thick twigs with dense branches and leaves, put on plastic bags, pockets up, pockets down, can collect condensate; or freshly cut leaves of fresh plants in large plastic bags, the temperature will increase Produce condensate; in the desert, choose a humid place to use solar heat to make water (Figure 10-1), and collect about 50mL of water in 24 hours; seawater and urine can also be distilled by distillation.

(5) Methods for finding water and purifying water

You can go to the upper reaches of the river to find water; look for water in the direction of the bird’s flight; find the water under the dry river bed; find the water at the lowest point on the outside of the turn of the river; find water at the foot of the plant at the foot of the plant; look for springs at the bottom of the canyon and under the slope. Tracking of human or animal footprints can find water (for example, honeybees leave the hive no more than 6.5km, most insects fly within a radius of 90m radius); to purify water, you can boil water, add a little salt, or bleach at home Agents, purified water tablets (1 to 2 tablets) and shaking uniform, can be drunk after half an hour precipitation.

In a severe water shortage, it is necessary to reduce consumption and reduce exercise. For example, talk less, don't smoke, nose-to-face encounters many people breathing close to each other; don't use your tongue to lick your own lips, you can wipe cracks, animal oils, or have pebbles or coins in your mouth to ease thirst; or in the sand Digging a hole in the ground and hiding it deep in the neck can block the evaporation of heat from the body's water, and piles the dug up sand next to the pit to provide a cool shade.

Note: You can't drink white wine if you are helpless and thirsty (African natives call it “tiger milk”).
