A little about air

• There's 15 tons of air weighing each of us down. We can't feel it cause of the pressure inside of our bodies.

• A human inhales about 11000 litres of air in 24 hour's time.

• Air consists of 78,1 % nitrogen, 20, 9 % oxygen, 0,9 % argon, carbon dioxide, hydrogen, helium, neon, krypton and other gases.

• In one year's time, 577 billion tons of water passes through the atmosphere.

• The massive energy of a hurricane or a typhoon is equivalent to the energy that is released in (estimately) 500 000 atomic explosions.
