I saw this a while ago; and thought it was quite intriguing. I don't think I've seen anyone debunk it yet either, but chances are it's not the entrance to Agartha. If there were more sources+ videos of the same thing I'd be much more interested, but as for now it's more of a visual stimulation.

Fake....watch closely and you'll see that it recycles the images going into the hole

if it was real,and it was videoed from space it would be out of view within a few seconds....
imo,well fake..

I totally agree fake as can be, nothing that huge could remain covered up, just an offbeat snippet from the bathroom stall of the world that i felt like sharing

Now if you'll excuse me I am going to go pack my chute and charter a plane to the south pole
