Water :Fun, Interesting & Cool Facts
Have you ever thought about floating ice in a glass of water, glaciers floating in oceans? And ice is solid! From what we know about matter, a solid should sink in liquid as solid molecules are denser than liquids, so why does not the ice, which is solid form of water does not sink in its liquid form. This is a unique quality of water. Its solid form is 9% less dense than its liquid form. Although 70% of earth’s surface is covered by water ,but total water on the surface of earth makes up just 0.025 % of earth’s total mass i.e. 25/100,000ths of the stuff of the earth.
· Pure water is so pure that one can’t even drink it. It tastes very bland & due to its solvent properties, it would absorb all the minerals from your tongue & your mouth would feel dry So few minerals are added back to water by water-producing companies so as to make it tastier & safe for your dinking.
· The two-litre bottle of a cola requires five litres water to produce.
· Water exists in almost every substance ,you eat or drink. Percentage of water in few items Milk-90%,Bread-30%, Meat-75%,Egg-73%,Cucumber-95%,Lettuce -95%,Tomato-95%,Potato-75%.
· Water exists in a fourth form too, despite it being so vast & important, it is never mentioned outside scientific circles .The vast quantity of water is locked in the rock deep in the Earth’s mantle ,in a layer about 410 kilometres below your feet.
· All the water on Earth came from space in exactly the form is in now i.e. H2O.
· Every hour, the Earth’s oceans are evaporating 50 cubic kilometres of water into the air (13 trillion gallons)
· Just the leaves from a single acre of trees might send eight thousand gallons of water up into the air in a day, which is enough to fill a normal swimming pool.
· A normal toilet uses 6-8 litres of water for one time use, so if you flush five times a day ,that means 30-40 litres of water being used by one person just for flushing toilets in a day.
· According to WHO, 1.8 million children die every year, either from lack of water or from diseases they get from not-so-pure drinking water. That no. is too high, in other words, it is 5000 children a day.
· Agriculture, producing food for us, uses two thirds of all the water people use.
· Do you know microwave cook/heat your food due to water only? Yes, water Molecules inside a cup of coffee or a potato, can spin 1 billion times a second, in response to the microwaves. This spinning motion causes heat, which cooks the surrounding food.
· Popcorn in a microwave pops when the 14 % of each kernel that is water, inside a corn grain, vaporizes into steam and expands the grain.
· You can use internet, your computer, your iPhone because of water only. These all are made by micro-chips, they are so tiny & pathways on them are of nano-size, even a slight impurity won’t let these microchips to function properly, so these microchips are cleaned by using pure water as water takes away all the impurities from path-ways due to its solvent properties.

• Lions may hunt at any hour, but they typically go after large prey at night.
• They hunt in a group to increase their chances, as larger animal can be difficult to catch and can outrun a single lion.
• The lions fan out in a broad front or in a semicircle to slowly attack on prey. Once with within striking distance, they join together among the startled animals and knock one down. They sneak up to the victim until they reach a distance of around 30 metres (98 ft) or less.
• Females do >85% of the pride's hunting as they are more aggressive, the males patrol the territory and protect the pride, for which they take the "lion's (major)share" of the females' prey.
• Lions are not always successful in the job, 50% of times their hunting adventure fails too.
• Females do 85 to 90 percent of the pride's hunting, while the males patrol the territory and protect the pride, for which they take the "lion's (major) share" of the females' prey.

- • There are between 17-20 living species of Penguins.
- • The largest living species is the Emperor Penguin- on average adults are about 1.1 m (3 ft 7 in) tall or more.
- • The King Penguin is the second largest species of penguin.
- • The smallest penguin species is the Little Blue Penguin also known as the Fairy Penguin.
- • The yellow-eyed penguin is believed to be the rarest penguin species, with only approximately 5,000 birds surviving , though population numbers fluctuate.
- • Winter arrives in Antarctica in March. Nearly all creatures leave except for the Emperor Penguin, the only animal that spends the winter on Antarctica's open ice.
- • Penguins are warm-blooded birds as humans but still lay eggs.
- Interestingly, male Penguin takes care of the chick. To keep eggs warm away from cold they balance their egg on feet and cover them with their belly flap..
- • After laying the egg, female Penguin leaves for about 65 days for feeding towards open seas, males stand, for about 65 days, through icy temperatures, cruel winds, and blinding storms. And they eat nothing that whole time.
- • After females return, the males eagerly leave for their own fishing session at sea, and the mothers take over care of the chicks for a while.
- • There are about 17-20 different species of penguin and around 100 million penguins are there in the world.
- • Penguins seem to have no special fear of humans. This is probably because penguins have no land predators in Antarctica.
- • Typically, penguins do not approach closer than about 3 meters (10 ft) at which point they become nervous. This is also the distance that Antarctic tourists are told to keep from penguins
- • Another interesting thing about them is if they lose a chick they steal from other mother.
- • Penguins can walk faster than humans even when they seem to waddle while walking.
- • Penguins know Yoga ! They can hold their breath for 20 minutes under water and can leap in water while swimming.
- • Penguins love to store stones that help them to float in water.
- • It is really funny that penguins steal stones from each other & there are sometimes fight among them for this.
- • Penguins can’t fly ,but their powerful flippers and streamlined bodies make them very good swimmers. They are the fastest swimming and deepest diving species of any birds.
- • Penguins’ eyes work better underwater than they do in the air, giving them good eyesight to spot prey while hunting, even in cloudy, dark or murky water.
- • Emperor penguins and king penguins do not make any sort of nests.
