Wow! Check out a crashing glass skywalk. The glass-floored skywalk, standing at an altitude of 1,180 meters, "cracks" when somebody steps on it. Actually, it was designed on the basis of digital 3D simulations to provide tourists with a thrilling experience. The glass skywalk, 266-meter-long and two-meter-wide, is built on East Taihang mountains in Handan city, North China’s Hebei province, about 500 kilometers southwest of Beijing.
