Unloved duties

The least favorite boys work is daily brushing. They recognize that it is necessary to brush your teeth, but at every opportunity seek to avoid this unpleasant lesson. Well in the woods — no need to brush your teeth: there is nothing to clean! Well, sorry for the forest people also need clean teeth and rinse their tonic, and for this there are opportunities.

The most simple — clean teeth powdered charcoal to torogo many in the fire. Coal — Good disinfectant and kills bacteria. Through charcoal filter nutrients, bleached sugar. Coal holds poison gas masks. Slices sprinkled with crushed coal plants to pre dohraneniya from rotting. Coal for healing plants — the same as iodine for wounds of man and animals. That black powder was more pleasant and resembles a real tooth, you can add it to the dried and powdered leaves mint.

Mint grows on damp places. In mint lavender flowers with four petals fused and four stamens. Leaves petiolate ovate, serrate margins, there are disgusted by quadrangular stem. It's easy to find the smell, rubbed the leaves. The name "Mint" — modified scientific Man, that (Mentha), descended from the Greek name nymphs Cops.

When you see a modest plant mint and inhale the aroma of the leaves, can not help thinking, as a branch mint shonku we saved lives and led to the greatest scientists of the mysteries of the green leaf — the secrets of air power plants.

English chemist Joseph Priestley sought permission dirtied ki how improved air, tainted breath of humans and animals. He put the experience with the little mouse: shonka we put in a glass case, dropped into the water edges. Mouse lived under surveillance for long. He choked on his own in the tainted air breathing.

After that, Priestley decided to try the plant.

Unloved duties

"I took — he wrote — some air, done entirely spoiled breathing mouse that died in it, divided it into two parts: one part of the air moved into the vessel, immersed in water, and in another part, also enclosed in a container with water, put a branch mint. This was in early August 1771. After eight or nine days, I found that the mouse pre red could live in that part of the air, which grew a branch mint, but the mouse was killed instantly in the other part of it. For seven days in a vessel with a broken air escape breathing mint grew almost 3 inches and also formed a few new ones. "

Thus, the plant as it was fed tainted air Hom, ie carbon dioxide. It grew, purify the air by absorbing carbon dioxide and releasing oxygen.

Opening Joseph Priestley made a big impression in the scientific world.

Royal Society scientists awarded a gold medal Priestley and honored at a ceremony. President of the Society, in his speech said the vast importance of the discovery Priestley, made on the basis of experience with a branch mint.

"This discovery, — the president — has convinced us that there are no useless plants. Starting with the magnificent ba doo and finishing small blade of grass, all are useful to humans. If not always possible to see the private benefit of the individual plant, then at least as a part of larger whole, it is involved in the purification of the atmosphere: in this respect, and fragrant rose and poisonous wolf berry have the same purpose, and in the most remote, uninhabited parts of the world there are no meadows, no forests, which would not be in a constant exchange with us, supporting and providing our lives. "

But after a short time, opening Priestley suddenly questioned. Scientists are excited, and the Royal Society asked Priestley repeat his experience in their presence. It was evening. In the large hall were scientists in robes and white wigs. Tallow candles were burning. All in silence intently watched what he was doing Priestley.

• You see, in the vessel with the branch mint mouse alive …

• No, he's choking … and dying — a voice.
Indeed, the mouse slowly fell to the side, pulled

feet and died.

Only much later, the Dutch scientist Jan Ingen Howes, who served as a doctor in Vienna, could explain the failure of experience Priestley.

"I noticed — wrote Ingen-Howes — that plants purify WHO spirit in which they live, not only for six or more days, as it seems from the experiences of Priestley, but much more likely, and that the reason for this must be sought not in plant growth, and in effects on them of sunlight. " That is why the repeated experience of Priestley in the dim, flickering light of the candles did not give the expected results.

So ordinary mint helped open a secret green stev — power plants with carbon dioxide in the sunlight.

Mint Since ancient times was highly regarded. In ancient Rome, sprinkled with mint water room, and the tables were rubbed with mint leaves to create a cheerful mood of the guests. CONSIDERING it, the smell of mint stimulates the brain, so the students in the Middle Ages instructed to wear on his head while playing a wreath of mint. Mint put into milk to prevent souring.

Mint, brewed in boiling water, good use when brushing your teeth as aromatic and a cooling rinse. Their mint flavor tooth powder mat makes more enjoyable. As a gargle for the teeth, gums and strengthens disinfectant, especially useful to use a decoction of oak bark.

Best angle for cleaning teeth — basswood.

Teeth brushed. Do not say that you forgot the tooth with a brush ku home — it's easy to make sprigs of spruce, pine, or, if you prefer a milder — with fresh sprigs of lime or aspen. Stick with one hand split into smaller parts and to bend them for greater softness. So clean it's teeth.

For many unpleasant duties include not only clean the teeth, but also clean the dress and boots. Dresses need to clean a brush minute. It can be done, using as a hard bristle roots of wild grasses. Forests and ditches, under bushes, mainly on sandy soils common reed, or kalyamagrostis epigeyos (Calamagrostis epjgeios). His name is made up of double words: "calamus" — "Cane" and "agrostis" — "bent"; "epi" — "on" and "gei" — "earth." In appearance it resembles the cane and bent grass, but grows on land, not in water, as a reed.

Spikelets reed green, with purple or dirty reddish, gathered in large compressed panicle. Leaves broadly linear, gray-green color. Calamagrostis height of 100 — 150 cm. He has a strong and long, a few meters, rhizomes, strengthening sands on the river banks. These rhizomes and roots of the spud, cut, fold in half and tightly tied into bundles — brush. Manages to do this and brush drilling (you can burn hot nail) hole in a wooden fence and plunging them into a rope folded bundles of bristles.

Brushes can be made from the roots of frequent cereal foxtail. Indeed, this cereal ear soft, fluffy loamy like a fox's tail.

If you have no time to look for these plants to brush, you can rip any turf grass, forming a tightly compressed bundle of stems.

And link it is not necessary, but just exactly cut the roots and stems. In this case, one side will be strong bristles, and on the other, where the stems — softer.

Can be successfully used a low, up to 15 — 30 centi meters, grass growing on the marsh, and wet meadows, and even in dry areas with thin sandy soil. It has a one-sided spike erect dirty purple. Learn this by withered grass stems. It is called Belous or nardus stricta (Nardus stricta), which means "strong", "sticking".

I took up an hour swamp.
There Belous sticks out like a brush, hard …
Ah! The beauty is in this desolation.
