Cactus water, liany, the roots, snow and ice


1 Carefully cut off the top of the cactus with a knife or machete, taking care, so as not to be injured by the spikes.
2 Beat the pulp inside to a mush with a stick. Soon water will start to collect on the surface.
3 The milky juice is sucked out with a long cane tube. Cacti can be exploited in this way only in cases of genuine danger; these plants grow very slowly, and some species are threatened with extinction in many areas.

1 Cut the vine high, as soon as you reach, with a wide knife or machete. Do not cut the bottom of the plant first, for the water goes up.
2 Prepare a vessel for water. Trim the lower end of the liana, put the pot down and wait, until it fills up with water.

Caution. The milky sap of plants is usually poisonous, such as the giant cactus Carnegiea, growing in the south-west of America.
Coconut milk and animal milk are high in protein, which needs extra water, so that it can be digested.
Coconut milk also has a laxative effect, therefore it can cause diarrhea, which in turn significantly weakens the body and may lead to dehydration.

1 Cut a young banana tree or figs approx 8 cm above the ground.
2 Hollow out the center. Soon it will fill with water sucked up by the roots.


Ice melting
Ice should be melted slowly. It is not worth melting the lumps of sea water, because they contain a lot of salt. Old ocean ice, such as a crab in the polar regions, it has a blue color and much less salt.

Snow melting
Prepare dense and kicking snow, excavated from under the snow cover. Pour it into a cloth bag and hang it over the pan near the fire. Do not top the snow directly in the pan set on fire, for all melt water is instantly absorbed by the snow, and the pan or saucepan begin to burn. remember, that with approx 40 cm3 of packed snow, can hardly be obtained 3 cm3 fresh water.
