Workers in China test glass bridge by smashing it with hammers
Warning: Don't look down!
Very, very brave workers in China tested the strength of new glass-bottom bridge by hitting it repeatedly with a hammer.
The bridge is a terrifying 300 metres above the ground.
And then, as if hitting it with a hammer was not enough, they drove a car over it too.
The bridge was to be tested to see if it was safe enough to be opened to the public.
We know it is a job that needs to be done, but not thank you - not for us!
