The ants lives in a castle, this was building uses a pieces of dust, if you see with determination, you can see the pieces of dust up one by one.
Building and putting a structure in form of a castle, but without any support, nothing to paste one by one the stones of dust, only put, but with a lot of caverns inside, to walk and move between this.
This is the most notable art of engineering, because if you as a human, come and put your hand in the castle or structure, you destroyed it very fast, this is complicate because we do not have idea sometimes, our feet were destrout an ants house and you only know when feel a lot of paint from angry ants.
This give to the ants the opportunity to build very fast the house very very fast.
The nature is wonderful, the ants too.
