1. Mysterious nature of water.
Indeed, water is mysterious and even the scientists could not fathom all the properties of water yet. Ideally, as per the physical laws, before freezing, water should become denser, however in reality its density decreases. Scientists are even considering the possibility that water has the capacity to retain the memory of whatever encounters it. This may be attributed to its dipole nature which is similar to the memory of the computer.
2. Immortality.
Many scientists claim that most of the water which is present today has been here since the time the Earth came into existence. Is it not astonishing?
