if you have just shy of 7 minutes to spare you may enjoy watching this amazing youtube clip titled Ants! and that’s what it’s about - ants. more specifically, the vast subterranean ventilation system and structure of an ant colony. it’s very fascinating. the researchers poured cement into the openings of the ant colony to create a casting of how the ant tunnels looked. that process took 3 days and over 10 tons of cement! excavation of the casting took over a month! now as a former ant, i can say that having cement poured into one’s home is really jacked up. but the end result is quite amazing.
