Hikers 'float' across crystal clear lake

Two hikers visiting a stunning winter landscape in Slovakia have captured themselves walking across ice so clear they appear to be walking on nothing at all.

It’s not a miracle, just a spectacular trick of the eyes.

Trekkers visiting the High Tatras Mountains in Slovakia noticed a lake nestled between peaks so clear it looked like they were walking on water – or air, depending on the angle.

In the video, which has been watched more than two million times, two hikers can be heard laughing in astonishment as they pick their way across the crystal clear ice.
