Casting a Field Ant Colony with Molten Aluminum. This is Anthill Art Cast #071. It's 17.5 inches deep and weighs 10.4 lbs. (45 cm, 4.7 kg). This one bubbled a lot because the tunnels are wide and that allowed the aluminum to flow in faster than normal, compressing the air and forcing some of it up through the molten aluminum. #ants #nature | Anthill Art
