Blizzard 1 is a typical T style gun using 1/4-inch pipes. It uses compressed air coming straight though the T to the nozzle and water coming in at an angle and turning with the flow of air to shot out the nozzle. The nozzle that works the best for this gun is a air filler tool from a Coleman Powermate air filler tool kit. It is a tapered hole with a final diameter of 7/64 of an inch. To control the water flow I have a 3/8 inch ball valve being feed by a 5/8-inch water hose. This is then goes to 3/8-inch piping. The air is controlled by a 1/4-inch ball valve and pipe that is feed by a 3/8-hose line with 1/4 connectors. The air goes though the straight part of the T while the water goes to a 90 degree elbow and then to the side of the T. the mixed water and air then go to the nozzle through a 1.5 inch long mixing chamber and exit the gun mixed together, freeze and fall to the ground.
    Blizzard 1 is capable of producing 1/2 inch per hour in bad conditions of about 26 with 60-70% humidity. It will make more in colder weather or with a bigger air compressor and nozzle.
