Watch an excerpt from the documentary “Ants! Natures Sceret Power” as scientists excavate an ant colony. This was done by pouring concrete into an abandoned ant colony and then excavating away the earth. This reveals an incredible an efficient structure that has highways and sideroads. The ants had to remove 40 tons of dirt in order to build this structure.
In another different ant colony that was not abandoned, scientists measure the air coming into and out of the ant tunnels and determined that it is analogous to an air-conditioned system where there are different shafts for incoming fresh air and outgoing carbon dioxide air.
