Wouldn't want to be on the bridge when this happened.

What do you do when the world’s longest glass-bottom bridge has finally been completed? You hit it with a sledgehammer, of course.

Ahead of the opening next month, bridge officials in China wanted to show the new attraction was safe, so they invited BBC’s Dan Simmons to put the glass panels to the test.

The video shows the top layer of glass shattering when hit. Watch to see what happens next.

Of course, even after a few more whacks, the bottom layers of the glass stayed intact, and the glass platform remained stable.

The new bridge, which stretches 1,410 feet between two mountains in the Tianmenshan National Forest Park in Zhangjiajie, has been engineered to withstand even more powerful blows as it is composed of three layers of ultra-strong glass.

The experiment comes after news of a glass-bottomed bridge in Shiniuzhai National Geological Park cracking under tourists as they took in the views from 3,500 feet in the air.
