To assure people that glass bridge is not that brittle, Chinese volunteers smashed the longest, largest glass bridge with a sledgehammer in China. Top layers could be seen cracking all over, but the bridge’s smashed glass panel withstood the torture even after a huge SUV drove over it to drive the point “it’s very safe” home. It seems that these glass panels on the bridge could be replaced and repaired easily. Obviously, the glass panels are made of multiple layers of glass, and these layers of glass are really tough. The glass bridge designer boasts it could withstand 800 people at once.
