reality. henry, good to see you. thanks very much. was that really the inspiration, or something else the inspiration for a self-healing material? basically, we wanted to try to create a material that acted like our body does to damage. specifically our bones. what we wanted to do is create something that could sense damage, like bone does. respond to try to stop its prop oh ga propagation and return back to its original configuration and obtain all of its properties that it had before. let s talk about this material that you ve developed. i want to show our viewers some video of this thing. i want the viewers to understand, there s already a rip in this material. it s not a rip, but that s the way it s supposed to be. it keeps repeating itself. the way you see it now in the blue is the way it is in its normal state. watch what happens. you ll see the rip come, and then you ll see there you go. you see that rip. see how it rips on the right
