NEW TYPE OF POLYWATER

1. Australian scientists have announced the discovery of a new type of polywater - а substance which as American scientist has claimed could destroy all life on earth. Two Sydney physicists, J. Middlehurst and L. R. Fisher, announced that they discovered the new type of polywater by accident.

2. Ten times as viscous as normal water and about 40 per cent heavier, polywater was discovered in 1962 by a Russian scientist.

3. Polywater has the same chemical composition as ordinary water but its properties are entirely different. Its molecules are linked in a long chain changing its physical properties readily, like plastic.

4. Russian researchers in 1962 said it kept its properties to about 1,000° F. and well below freezing point.

5. Despite widespread scepticism that such a man-made substance really existed, laboratories in the United States and England repotted they had prepared small samples of the substance.

6. This led to a warning from Dr. Frank Donahoe^, s of Wilkes College, that polywater could destroy all life on earth. He claimed that if it got loose and combined with normal water, the earth would become a hot, dead world like Venus.

7. British scientists discounted Dr. Donahoe's warning and said that only a few millionths of a cubic centimeter of polywater existed and all evidence pointed against it being dangerous.

8. The original type of polywater was formed by condensing vapor inside extremely fine capillary tubes of silica (silicon dioxide), the hydrogen atoms in the water linking with oxygen atoms on the surface of the silica

9. The Australian researchers discovered their polywater called fluorite polywater white studying water in food at the Commonwealth Scientific and Industrial Research Division of food preservation.

10. The condensed water vapor between two flat plates of fluorite and hydrogen atoms linked with atoms in the fluorite.

Слова и пояснения к тексту

by accident – случайно, нечаянно
