Grand Canyon Skywalk Nearing Completion

Imagine stacking the Taipei 101 building (current tallest building in the world) on top of the Sears Tower, going to the top and looking straight down.... Amazingly, the Grand Canyon is 4000 feet deep at parts and they are currently constructing a glass walkway that cantilevers out over the cliff. Since it is made of glass, visitors will have to wear protective booties when walking on it as to not scratch the surface. While neat, this exemplifies the difference between America's overprotective, insurance fearing society and our friends down under. If this thing was in New Zealand, they would be bungee jumping off the sucker.

And it won't fall down anytime soon
