China has recently opened their glass-bottomed bridge that sits 590 feet in the air, right above they central Hunan Province.
The "Haohan Qiao" is known as the latest series of glass-floored attractions to open in the world. Although it looks quite terrifying to walk, the bridge is completely safe. Each panel of glass is 24 millimeters thick which is approximately 25 times stronger than normal glass. One of the constructors of the bridge stated that even if people were to jump on it, it will still stand strong.
The bridge was originally made of wood, until China decided to experiment and make it out of glass. Just by looking at the pictures this bridge looks pretty scary to walk on. Most people close their eyes or even sit on the bridge because they are so terrified to go across.
