I'm not sure that the ants would be particularly happy about this research project but the final result is really quite amazing.
Basically, researchers pump concrete into a giant ant hill. It takes a little bit longer than they expect (3 days to be precise) and they get through 10 tonnes of concrete.
Then they leave the concrete to set and three weeks later start excavating the site to revile what the inside of the colony looks like. The result is an intricate structure, equivalent in labour to humans building the Great Wall of China.
Worth a watch and a great resource to support the teaching of science.
