Good ol’ H2O, seems like a pretty simple substance- a transparent fluid which is found everywhere in the world’s streams, lakes, oceans and rain. Though common, without water, we’d be nothing. Just dust. We all know how vital it is for our existence and we all also think that we probably know all there is to know about water. Today we unveil some out of ordinary facts about the incredible compound that gives us life and sustains the planet around us. Here are a handful of interesting facts about water.
2. Water requirement
Remember how everybody says that we should at least drink 8 glasses of water every day. Well did you know it actually takes about 12 gallons per day to sustain a human if we include all uses for water, like drinking, sanitation and food production.
3. Body water
We all know that a human body constitutes about 60% and 70% water. But did you know that this keeps changing at different times of your life. A human fetus constitutes around 95% water for the first months, getting to 77% water at birth and 60-70% water in adults. There is 42 liters of water in a 70kg person.

4. Even bones are watery
Yes, as a matter of fact the bones are watery and contain 31% water. The skin is 64% water, muscles and kidneys are 79% water and guess what 70% of the human brain is also water. Two-thirds of entire water in our body is within our cells.
5. Vending machine for holy water
Put a coin into the machine and it will dispense holy water. Well the idea doesn’t seem surprising at all. But imagine this happening back in 1st century AD. Now this is surprising right. The first ever known vending machine dates back to the 1st Century AD and it used to dispense holy water. Talk about innovation.

6. Speaking of innovation
I am sure nobody cares much about billboards but after hearing this you just might. In Peru, there’s a billboard that creates drinkable water with nothing but thin air. The billboard works on a reverse osmosis system, captures the air humidity, condenses and voila! You get clean drinking water.

7. Bottled water
Remember how we grab a bottle of mineral water every time out in sun during summers. Just know this that 1/3 what the world spends on those bottled water in one year could pay for projects providing water to everyone in need.
8. Water in space
It’s true! Scientists have found a big, really big pool of water (actually water vapor) just floating out there in the space. And when I say big I mean 100,000 times larger than sun big! It has water equivalent to 140 trillion times all the water on the earth’s ocean.

9. Drinking water made from poop
Don’t be stunned! We all know the problem of water shortage so how do you come up with clean drinking water? Easy — get the water from poop. Yes! I mean human feces. Bill Gates wants to convert your poop into clean and hygienic drinking water, and he’s got just the machine to do it- the Omniprocessor.

10. Walking on water
Not us humans but small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface.

12. Heavy bombardment of water
Did you ever wonder where all the water on earth came from? All the water on Earth arrived during a period called the Late Heavy Bombardment between 4.5bn and 3.8bn years ago in comets and asteroids. Though it’s a hypothetical event, we’d like to believe it.
13. Water from sun and stars
We all think of sun and stars to be hot gaseous bodies but do you know the fact that the Sun and other stars like it create 100 million times the water in the Amazon River every second.
14. Water on Saturn’s moon
It has been found that there is a hot ocean under the ice crust of Enceladus- Saturn’s moon. Since a hydrothermal vent at the bottom of one of the Earth’s oceans is where life started on our planet, the astrobiologists think that Enceladus can be the best candidate to look for alien life.
15. Water can cure depression
16. Stages of water
Quick: water exists in how many stages? If you answer three – liquid, gas, and solid you’d be wrong. Flabbergasted? There are at least 5 different stages of liquid water alone and 14 different phases of ice that scientists have found so far.
17. Ultraviscous and Glassy water
It turns out that at -38 °C even the purest supercooled water spontaneously turns into ice with a little audible “bang” no less. But if you continue to lower the temperature at about -120 °C something strange starts to happen: the water becomes ultraviscous, or thick like molasses. And below -135 °C, it becomes “glassy water,” a solid with no crystal structure. Remember “glassy water” not a glass of water.
18. Does water have a memory?
Memory of water is popularly associated with homeopathy. In a homeopathic preparation of a dilute solution of a compound, no molecule of any active ingredient remains in the final product but the solution somehow retains a “memory” of the solute. Homeopathy proponents explain this paradox with a concept called “water memory” where water molecules “remember” what particles were once dissolved in it.

19. Instant Snow with Boiling Water
Snow is supposed to be freezing cold… So boiling water…? Confused…? Well if you throw boiling water in to the air in subzero weather you’ll get instant snow. Interestingly, it only works with nothing less than boiling hot water.
20. Water intoxication
No, it is not some kind of water pollution. It’s the condition which follows when you drink excess of water. Drinking too much of water in a short time can be dangerous as it can cause the level of salt, or sodium, the blood to drop too low. It’s very serious, and can be fatal. Excess of anything is actually bad, even water!
