water is mixed with fire suppressant polymer in a mixer absent a power source . the mixer receives water through a water inlet with water exhibiting high velocity and associated hydrodynamic force . such velocity is achieved by locating the water inlet connected to a float or other part of an aircraft so that when the aircraft flies over water with the float dipping into the water , water is driven through the opening and into the water inlet of the mixer . a polymer inlet passes into the mixer . a bend is located downstream of the water inlet and the polymer inlet . the bend exhibits sufficient resistance to fluid flow direction therethrough that the polymer is sheared and thoroughly mixed and activated with the water . a colorant inlet is optionally provided within the mixer and the water and polymer mixture is then discharged into a tank for later utilization at a firefighting location .
