Impact 1 (IMAGE) Rice University Caption Tubulane-like polymer structures created at Rice University were better able to handle the impact of a bullet than the polymer reference cube at bottom right. The bullet stopped in approximately the second layer of the tubulane structures, with no significant structural damage observed beyond that layer. Bullets fired at the same speed sent cracks through the entire reference cube.
