These are the red imported fire ants which are harmful to the environment and their nests are exterminated by the millions in the United States using poisons, gasoline and fire, boiling water, and very rarely molten aluminum. What you get when you pour molten aluminum into an ant hill? An amazing sculpture is made by pouring molten aluminum into a fire ant colony. The resulting cast is huge, weighing 17.9 lbs. and reaching a depth of 18 inches.
