AUXETIXAUXETIX- objects that actually get fatter the more you

stretch them- derived from the Greek word αὐξητικός

(auxetikos) which means “tends to increase" and has its root from theword αὔξησις, or auxesis, meaning "increase" (noun). This terminology was coined by Professor Ken Evans of the University of Exeter

- Scientists have known about auxetic materials for over 100 years, but have only recently given them special attention

In using Seat Belts :In using Seat Belts :In an immediate break during a car ride, In an immediate break during a car ride, the passenger is usually thrown forward. In the passenger is usually thrown forward. In attempting to restrain this movement, the attempting to restrain this movement, the seat belt gets stretched and, much like an seat belt gets stretched and, much like an elastic band being pulled, becomes elastic band being pulled, becomes narrower. This is exactly the opposite of the narrower. This is exactly the opposite of the behavior that you want, for, in getting behavior that you want, for, in getting narrower, it concentrates all the forces into narrower, it concentrates all the forces into a much smaller area.a much smaller area.
