WELDED A FAN TO A MOPED!!
Check out this clever contraption! Chinese craftsmen have come up with a brilliant way to combat cows' main enemy on farms. Instead of expensive chemicals, the farmers built a mobile vacuum cleaner: they welded a regular duct fan to an electric tricycle and attached a mesh bag. In just one morning, this system sucks up over 2 kg of flies!
