| A pair of fibrous strands called chalazae anchor the yolk inside the egg, and Geary figured that sundering them would allow the yolk to float to the center. |
| In addition, the layers of albumen act as a cushion to protect the embryo from jarring movements, while the chalazae help to maintain the orientation of the embryo within the egg. |
| The chalazae suspend the yolk at the center of the egg with two strong bands that connect it to the shell. |
| Wait too long and the yolk will be off-center, as the white and chalazae deteriorate. |
