Survival on the Island starts with a female boss

Chapter 19 Picking Up Trash

For an adult, scientific research shows that the best state of drinking water every day is about 1500 to 2 thousand milliliters.

At least 500 milliliters of water is needed to maintain the state of life needs, but the most basic thing to keep a person alive is to drink at least 1000 milliliters of water every day.

So obtaining enough water source is the most urgent thing for Ma Yongqiang and Yu Tina to solve.

Finally, after discussion, it was decided to rely on Ma Yongqiang's hands-on construction ability developed in rural life since childhood, while Yu Tina used the knowledge she had learned to direct and design the plan.

After explaining and explaining with Tina, Ma Yongqiang decided to build the most time-saving and effective way to obtain fresh water first.

Yu Tina's original words are explained as follows:

"Sea water is very salty and cannot be drunk directly. We can use simple distillation to desalinate the sea water. Similarly, you can choose to dig a sand pit on the beach, then put a container in the pit, cover it with plastic film, plastic film The tip of the cone is just in the range of the container mouth, so that the evaporated and condensed water vapor can be drained into the container along the film for easy collection.

Or find a relatively dry beach on the beach and dig a hole. Generally, fresh water can be dug out. Because fresh water is less dense than salt water, it is likely that some fresh water layers will float on top of the denser sea water layer.

Rainwater is often abundant along the coast or in the sea, and fresh water can be obtained by collecting rainwater. This is also a simple method. Digging holes on the ground and then covering them with plastic films can effectively collect rainwater or container collection.

Look for palms by the sea, where there is often an abundance of sap in the fruit or trunk. "

Generally speaking, the best way to obtain drinkable fresh water in the wild, and the least labor-saving way is rainwater, but this requires too much luck. Simply put, it depends on the harvest.

Of course, you can also prepare some water containers in advance and put them in an open place. If there are enough water containers, and the weather is beautiful, it will be a wonderful thing.

Others are time-consuming and labor-intensive. Whether it is taking water from tree trunks or using steam to condense fresh water, it is time-consuming and patient, and it is very likely that what you get is not proportional to what you pay.

All in all, anyway?At present, collecting some clean containers such as bottles and shells that can hold water is the most important first step at present.

Fortunately, human civilization is now spread all over the world. It is easy to find some mineral water bottles on most beaches, although these white garbage will cause some great harm to marine life.

But for Ma Yongqiang and Yu Tina, these bottles and cans all represent the hope of survival.

If it doesn't work, you have to live on this isolated island for a long time. Without these garbage gifted by human civilization, it is really difficult to survive on this isolated island with your own hands.

The two of them opened the tattered king who was frantically picking up tatters on the beach, and the tattered bottles were collected together.

Although most of them are dilapidated and basically unusable.

But there are still some complete bottles that have been dug out. Of course, besides these bottles and cans, there are also some other sundries.

For example, if you have room, you are very lucky to pick up a rotten fishnet with twisted fish.

The biggest harvest is the iron oil drum that Ma Yongqiang picked up at Jiaoshitan, the size of a biscuit box.

With such a sticker box, it means that the two can cook over the fire.

Ma Yongqiang hugged the iron oil barrel excitedly, and kissed him hard, he was so excited and happy.

Because when Ma Yongqiang picked up the iron bucket, he had a flash of inspiration. He thought of the survival programs he had watched, which made simple tools out of iron sheets. Although simple, they were also very sharp.

Ma Yongqiang, who returned to the campfire, first carefully smashed the lid of the iron bucket with a stone.

Then the relatively complete part is polished along the straight edge to make a knife edge on the stone.

I tried it with a waste bottle I picked up. Fortunately, it is not very sharp, but it is barely usable.
