The circle was filled with hundreds of strange crystals.
The peculiar phenomenon, which was found by the teenagers in the middle of a frozen lake, consists of a circular feature filled with strange white crystals that seem to defy explanation.
In the video the two youths can be seen inquisitively poking and prodding at the objects while jokingly referring to them as ‘alien eggs’ due to their ‘gross’ and ‘slimy’ consistency.
The footage has proven quite popular since appearing online with Internet users offering explanations ranging from a frozen puddle of paint to a meteorite impact crater.
Some have even suggested that it could be some sort of viral marketing campaign.
So far however no definitive explanation for the phenomenon has been found.
While there’s no proof the creepy discovery is linked to creatures from another planet, there has been a lot of speculation about what it could be.
One Reddit user suggested the frozen goo might be something decidedly less sinister. They wrote: “A big blob of off-white paint then spread out into a circular pattern. Paint can solidify into strange shapes.”
Many others refuse to believe something so pedestrian could have caused the strange shape, pointing out it’s unlikely paint would make a circle filled which such uniform shapes.
Other guessers suggested the eggs are actually the remnants of a fire, part of an aeroplane that’s fallen to the ground, a rare breed of jellyfish or nuts which have been buried by a woodpecker.
Fungus or a meteor were other top picks, as was something to do with coffee – the camera pans to an old cup at the end of the footage.
Some are also wondering if the clip could be a cunning viral campaign for a new movie.
