It looks as though two hikers are walking on water in this YouTube video.
The lake is actually frozen, according to Thomas Nunuk who posted the clip.
The hikers appear to be crossing the crystal clear frozen water in the High Tatras Mountain of Slovakia.
According to the Huffington Post, experienced hikers said the ice looks to be about 2 centimeters thick.
Some viewers are amazed, others say it can’t be real.
