A Steaming Mystery

The image you see is of the exact state of the ant hill after the molten aluminum makes its way down to the base of it. The astonishing thing that the image is incapable of revealing is the constant movement of the mound making it seem like someone has put life into it. Along with the movement, the mound also starts to produce hissing sound and gargles continuously. Till then the molten liquid finds its final resting place inside the mound. The strange series of events ends with the hill moving for one last time with steam constantly rising above from its surface.
