Long ago in China, someone notices wasps making a net. The bug bites bits off wood, chews and spits them out to from the wasp nest. The person get the idea for making paper. Today we write on paper still made from bits of woods. Can you imagine human history and our everyday life without paper?
Someone notices bug spit in nature and humans get a way to write down to our ideas to share today and with the future.
