“The meeting of two personalities is like the contact of two
chemical substances: if there is any reaction, both are
transformed.”

* Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it
* If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass
* The chemical name for water (H2O) is dihydrogen monoxide
* There is about 1/2 lb or 250 g of salt (NaCl) in the average adult human body
* The only letter that doesn't appear on the periodic table is J.
* Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the atmosphere.
* The human body contains enough carbon to provide 'lead' (which is really graphite) for about 9,000 pencils.
* The rarest naturally-occurring element in the earth's crust may be astatine. The entire crust appears to contain about 28 g of the element.
* Approximately 20% of the oxygen in the atmosphere was produced by the Amazon rain forest.

Did you know Walt Disney in one of his cartoon films introduced the concept of chemistry in his own way.Let me narrate the story to you...
One day a business man thought of buying a coal mine. He bought it. His sons who were very young claimed "OH! DADDY WHAT A WASTE OF MONEY"
Dad said "FINE! IT'S MY MONEY YOU DON'T HAVE TO WORRY ABOUT IT"
Then one fine day the businessman started growing peanuts on the surface of the coal mine. His sons exclaimed"OH! DADDY WHAT A WASTE OF MONEY"
Dad said "OKAY! IT'S MY MONEY YOU DON'T HAVE TO WORRY ABOUT IT"
Days passed and the peanuts grew. One day the son came running to the father and said" DADDY! SOME ELEPHANTS FROM THE NEARBY JUNGLE CAME,ATE ALL THE PEANUTS, AND DESTROYED THE PLANTS."
The businessman and the sons went to the area and found that the elephants had already gone. They were about to return when the sons found some thing shining on the ground. To his surprise they were shining all over the coal field. After much observation they discovered that 'THE ELEPHANTS HAD SO MUCH WEIGHT AND THE CREATED SO MUCH PRESSURE THAT THE COAL STARTED TURNING INTO DIAMONDS.'
Father smiled and disclosed "I KNEW THAT I WOULD RECOVER MY INVESTMENTS!!!!"

Walt Disney in a childish manner explained the children that under huge pressure (& temperature-{not included})the coal gets converted into diamond.
