Wasp nest paper surface. Wasp nest paper is actually stronger than the same thickness of human-made paper because wasps reinforce it with saliva that acts like a natural glue, creating a composite material that engineers have studied for inspiration in developing stronger, lighter building materials. It's basically nature's version of fiberglass, and scientists have discovered that this ancient design is so efficient that some modern construction companies are trying to replicate it.
