If you're that high up the tower to start with the odds of you making it out alive if the ball fails are pretty slim. Might as well stay and watch the ball swing. Why not?

If you're up that high, stop standing on a stool and get a ladder. “it pretty much does what you do with your own weight when you are standing on a stool changing that light bulb and it starts to sway.”

Very well done article, highly informative. The video could be better, but it's amazing as it is. Does the Sears tower in Chicago have a pendulum? My aunt worked there years ago, she said she could often feel the building swaying. Intriguing. Very well done article, highly informative. The video could be better, but it’s amazing as it is.

This is the first video I've seen showing the counter weight moving. Very impressive! Wow, I read about this a while back when the building was being built.

There is a fascinating video of the Taipei-101 tuned damper during the recent earthquake in mainland China (Sichuan) at http://www.popgive.com/2008/06/amazing-728-ton-stabilising-ball.html You can see the large crowd of onlookers who rushed to the core of the building to see the giant ball in action.
