Water vapour has been discovered in other parts of the universe including Venus. It is the biggest greenhouse gas!

Only 0.035% of all the earths H2O is found as water vapour in the atmosphere.

Icebergs float because H2O expands as it freezes.

Water is actually the biggest greenhouse gas & stops us freezing to death!

The driest place on earth is Death Valley, California, USA although people do dispute this!

The wettest place on earth is Tutunendo, Columbia with a very wet annual rainfall of 12 meters.

For centuries the moisture content in the air was determined by measuring the length of single human hairs.

Moisture in the air improves the quality of silk production in China & textiles in Manchester.

Moist air is actually lighter than dry air, & even Newton was not believed on this one!

In the 1840's, ice was harvested in huge quantities in Massachusetts, USA and exported to London, England to be served with drinks.

The human body is largely made of water with brain cells being 82% H2O !
