A manually operated hydrodynamic cavitation water device formed from a cylindrical bottle having an internal chamber constructed and arranged to cause hydrodynamic cavitation of water placed within the bottle upon vigorous shaking. The bottle includes a series of plates positioned within the bottle having a plurality of bi-directional orifices designed to control the velocity of water with each said orifice. Each plate further includes a edge shape to induce shearing, which together with the plate orifices are constructed and arranged to create micro bubbles to create OH-radicals.
