World's highest, longest glass bridge invites sledgehammer to test safety

The Zhangjiajie Grand Canyon Bridge, the world's highest and longest glass bridge, is set to open in Hunan, China, in July. To assuage the fears of any tourists who may attempt to walk across the bridge which stands nearly 1,000 feet off the ground, the operators invited reporters to test its glass panels with a sledgehammer.

BBC reporter Dan Simmons can be seen in this video carrying out the safety test, hitting a glass panel more than a dozen times with a sledgehammer. While the top level of glass is shattered, the panel itself remained intact, even holding 25 people in a single pane, while they jumped on it.

The bridge, which stretches more than 1,400 feet across two cliffs and can hold 800 people at once, was designed by Israeli architect Haim Dotan.
