The title of this Russian video, "Рыбный гейзер", translates to "Fish Geyser". Why it's called that, I have no idea. Can someone please explain how this is even possible? The best explanation someone came up with is this:
"My guess is that the ice formed a very tight and sturdy seal for the pond, and the water below got supercooled due to the pressure. When the hole was drilled, the supercooled water froze and expanded, forcing water through the hole. I have no idea if there can be enough pressure in such a Pond to supercool water...meh probably not..."
