The Arvind Kejriwal government is arming itself to shoot down, literally, the lethal Delhi smog. This device, which was tested recently at the Delhi secretariat, is called an "anti-smog gun". Connected to a water tank, the anti-smog gun sprays atomised water into the atmosphere. The fine water particles work like rain, sticking to the deadly particulate matter suspended in the air and bringing them down. The device is mounted on a vehicle, so it can be taken across the city.
