I'd jump up and down on that glass to piss people off
Spectacular experience, I'd love to go up there. We have the stupid Shard here in London and they want £20 just to go to the top and see the views. Robbing gits.
They had that 'leap of faith' thing on Blackpool Tower many years ago. What a crock. It was so steamed up and dirty you could hardly see through it.
