Groovy! These grooved patterns better mitigate shock waves

Engineers have discovered a method that could make materials more resilient against massive shocks such as earthquakes or explosions. They found that cutting small grooves in obstacle materials diminished the impacts of what's called the reflected shock wave--once the initial wave has hit the spiral of obstacles and bounced back.
