Bangkok smog: 50 drones to be launched spraying molasses to relieve smog

Bangkok is preparing to launch 50 drones tomorrow for spraying water in the skies over the capital. The water will contain molasses to aid in the attachment to smog particles.

The Thai News Agency is reporting that Bangkok Governor Aswin Kwanmuang says they have contacted a drone club in Nakhon Ratchasima to get 50 drones which can carry 10 litres of water each to fly over Bangkok.

The water will contain molasses which and is predicted to help relieve the smog problem. Scientists say that the molasses will assist in the trapping of smog and cause it to fall onto the ground as black drops (great result if you happen to be walking underneath at the time). Water trucks are being prepared to clean roads and vehicles which might be affected tomorrow.
