In an effort to reduce such a nasty risk, Nascar has turned to scientists at Battelle, an R&D company in Columbus, Ohio. Their solution: a new hyper-elastic material called FlexAll that deforms to absorb an incoming force and then bounces back to its original shape within minutes. After molding the FlexAll into honeycomb-like columns, the researchers repeatedly slammed racecars into it at speeds up to 100 mph. The plastic behaved identically crash after crash, absorbing 92 percent of an impact's energy each time. In road tests, the cushion reduced maximum G load on the driver by an impressive 60 percent.
