Bulk water - the water that comes out of your tap is made up of long chains and random clumps of water molecules and the other compounds dissolved into it.
However, when water flows over pebbles or through various devices that forms vortices within it,
the water begins to break up into smaller and more symmetrical structures.
The smaller these clusters are, the easier it is for that water to be absorbed by living cells.
The larger clusters or clumps of water require energy to be broken down to used in the cell and
is therefore a demand on energy.
The measure of any 'water energiser' is the degree to which it brakes down the water to create these micro cluster structures. There are numerous devices on the market.
