VIDEO Hitting a glass bridge with a sledgehammer

In case you haven't noticed, China has got a thing for glass bridges recently. They're building the structures all over the country including viewing platforms for those who really want to find out if they're afraid of heights.

It's a slightly strange national obsession but one that has produced some incredible feats of engineering, including a 430 metre bridge over the Zhangziazie Grand Canyon which is mostly glass and will be able to hold more than 800 people at a time when it opens to the public in July, 2016.

Recently there were fears over safety when a glass panel was cracked at a different platform. Naturally to combat those concerns, a fellow from the BBC stood on the new bridge and hit the glass with a sledgehammer.
