Toucan: The Original Crash ProtectionHow a beak's design is inspiring safer vehicles.

Nature Solved It First

The toucan’s beak is an engineering marvel, combining incredible strength with a surprisingly light weight. Its secret is a rigid outer shell filled with a bony foam, a structure that’s mostly air. This natural design is highly efficient at absorbing impact. Now, scientists are copying this model to build stronger, lighter materials for everything from airplane parts to protective car panels.
