Problem:
Concussions are caused by dangerous sports, and the design of the helmets used are not optimal, thus are not as efficient as could be at protecting the head.
Biomimicry Idea:
An idea would be to create an more protective football helmet that is safe from impact using paper mache and cardboard for the protection as a 3-D model.
How does Nature help the Woodpecker not hurt its head?
Woodpeckers hit their heads on trees their entire life, but never hurt themselves. Their skulls have adapted to that impact on the same spot so it keeps them safe from harm. The inside of a woodpecker’s skull is made of a bone that is firm, but spongy.
I made a paper mache model.
