Strong screen

Again a nice conversation with a friend of ours. He works at an electronics firm and they had to deliver a custom designed lcd screen that is capable of being demolished. Really, they did tests with it where they dropped a metal ball of 10 kilogram from a height of 2 meters on the screen! They found it stayed in one piece as long as the ball hit the screen in the middle of the screen, so it wasn't really good. Apparently hooligans and other weird people do not always smash objects in the middle, so they still had work to do.
