Heavy water contain deuterium, a hydrogen isotope having one neutron.
contains the isotope deuterium
"Heavy Water" still has the formula H2O, but the hydrogen in the water has a neutron as well as a proton- much like Helium does. It still has it's one electron however. Heavy water is used in NMR as a solvent for organic chemicals in proton NMR- to avoid interference on the spectra.
It has no taste or smell.
Heavy water has also been called deuterium oxide, D2O.
The property of water allowing some insects and other animals to walk on its surface is called "surface tension".

The specific property of water evaporating is called evaporation. During this process, water changes from a liquid state to a gaseous state due to heating.
The term for heavy continuous rainfall is "downpour." It refers to a sudden and heavy rainstorm that can cause flooding and other water-related issues.
A deluge of water is commonly referred to as a flood. It is an overflow of water onto land that is usually caused by heavy rainfall or overflowing bodies of water. Floods can cause significant damage to property and endanger lives.
Water requires a lot of energy to raise its structure and to evaporate.
Surface tension.
So you take some water...a lot of it. Then you have heavy water.
