Can you boil water in the wilderness without a kettle or pot, is a quite common question. The short answer is yes and knowing how, could save your life one day, because it is a survival water purification method.

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes.

Purifying water by boiling is as a method of killing microbes that may be present in the water. The sensitivity of different micro-organisms to heat varies, but if water is held at 70 °C (158 °F) for ten minutes, many organisms are killed, but some are more resistant to heat and require one minute at the boiling point of water.

Boiling water in a paper is simple. First you need a fire. If you have your fire large enough, you can move on to your survival water purification. Then you need a paper cup. Fill it up and out it into the fire. Wait until the water starts to boil. You see, boiling water over a campfire is pretty easy.

There are several methods for boiling water over a fire. You can try boiling water in a plastic bottle or a bag, over fire, in a paper cup or in a condom also. But keep in mind, that it is wise to use plastic bottles and bags for water boiling only in extreme situations, because it can be dangerous to your health. High temperature makes all sorts of chemicals leak out of the plastic which then dissolve into the water. If you want to stay on the safe side, use other methods for purifying water in the wild.

Üleelamisõpetus, kuidas pabertopsis vett keeta. Vee keetmine pabertopsis ei erine oma olemuselt ükskõik millise vedeliku keetmisest ükskõik millises anumas. Põhimõte on sama – tuleb saavutada ja säilitada keemistemperatuur. Keemistemperatuurini jõudmiseks on vaja vedeliku temperatuur tõsta punktini, mil vedeliku aururõhk saab võrdseks välisrõhuga. Sellega kaasneb keemine, mis teisisõnu tähendab aine üleminekut vedelast olekust gaasilisse. Selle iseloomulikuks tunnuseks on vedeliku sees tekkivad küllastunud auru mullikesed, mis üha kasvades tõusevad pinnale ning paiskavad auru vedeliku kohal olevasse ruumi.

Tee tuli üles ning täida tops veega. Pane see lõkkesse ning oota, kuni see on keema läinud. Nii lihtne see ongi, aga pea meeles, et vedelikukindlad pabertopsid ei koosne ainult paberist, vaid neis on ka plastikut. Ja plastik on teatavasti inimese tervisele kahjulik, mistõttu pole otstarbekas sedasi vett kogu aeg keeta.

Kindel on aga see, et kriisiolukorras on parem valida võimalik surm kunagi kauges tulevikus plastiosakeste tõttu kui peatne surm dehüdratsiooni tõttu või reostunud vee tarbimisega tõenäoliselt kaasneva massiivse kõhulahtisuse tagajärjel. Nõus? Plastnõus!
