More into the blue than out of the blue, we've been scratching our heads ever since we saw this video at FDL HQ. It shows a group of men ice fishing in a very unusual way and has racked up over 3 million views on Youtube.
Filmed at Lake Saarijarvi in Vaala, Finland, it shows divers performing impossible tricks, such as kneeling on water and somehow shoveling liquid into a bucket.
The appearance of the rubber duck makes this underwater video escapade all the more surreal but the overwhelming serenity and feel is rather hypnotic. To many online it poses the obvious curious question: 'how did they do that ?' Can you work it out ?
