It is a story of a water drop. A thousand years ago nature has gifted the water drop with an extraordinary capacity: capacity of regeneration and the mission for renovation. From then on the water molecules have been circling and reviving the Earth for centuries. Water drops, once supplying dinosaurs, today quenching our thirst. The water drop is an essential part of our lives. We never know where and for whose life it will be indispensable.
The water drop has an optimal shape which can be captured by plenty of water molecules. This phenomenon has been named by scientists as the surface tension and it means that because of the attraction between molecules the liquids automatically shape into drops. The surface tension enables the surface of numerous water drops to behave like a flexible plate which is used by some creatures for walking on water.
People have not yet found out how many water drops are in the Universe but we know that they were created at the birth of the stars. But how are stars born? The birth of the stars is accompanied by different gases and elementary particles. When these particles hit the gases with high speed, powerful waves are created which compress and heat the gases. In this hot and thick gas the first drop was born. And then the second and the third and...
