The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures. Although buckling could be the dominant mechanism that triggers invagination, it has never been possible of measuring the tiny forces involved. This gap has finally been filled.
