This 38-second video shows three hikers walking across the clear frozen lake. And while many viewers were amazed, others doubted that the video was real.
As reported by Daily Mail, one experienced tourist Igor Ludma, from Slovakia, was able to give a scientific explanation for the fact that the ice look like glass, saying: ‘It is only possible when the temperatures fall from being relatively mild to very cold very quickly, and at the same time it’s important that there has not been any snow which tends to make the ice very cloudy. And we have had those conditions lately which would explain this very clear ice.’
