The Grand Canyon Skywalk...

I just saw this in Helen's John Lewis magazine. Its the new Grand Canyon Skywalk opening 1 Jan 2007. You will be able to walk out over the Grand Canyon and and look 4,000 feet down into the Colorado River while standing on four inches of glass! The skywalk will be built with more than a million pounds of steel beams. It is designed to support the equivalent of 72 Boeing jets and withstand an 8.0 magnitude earthquake 50 miles away but I'm not sure I would walk round it?!

You can find out more and watch a video of the making of it here.
