What is this smoke ring above the lake of Zurich? A Big Pothead? A new type of UFO? A heat phenomenon? Someone smoking a large joint? American Indians making smoke signals? A mirage? A volcanic eruption?
Although this event remains a mystery even for scientists, lots of people were amazed in front of this odd sky phenomenon.
At the beginning the bizarre small cloud ring had a diameter of about 10 meters. After a few miles of travel it was around 50 meters wide. During its trip, it always kept its spherical shape. The ring continued to rise in the air and got lighter and lighter until it finally completely dissolved. Than, the nightmare was over.
Scientists from Meteo News suspect a special fireworks, which could have exploded over the lake. They say the event is certainly not natural. It looks as if something had been shot from a cannon with a lot of pressure and exploded. The cloud in form of a ring would speak for this thesis!
In a similar way, somebody says it could be related to a hail cannon, which is fired when large thunderstorms form to prevent from hail. In the same way also reach us by speculation that it will be the mysterious circle around a bee or mosquito swarm.
