Here’s a 730 Ton Damper Ball that keeps Taipei 101 building in Taiwan stable, even during the Chinese earthquake as shown in the video.

Here’s how it keeps it stable:

What’s interesting about the 101 is that it has a gigantic suspended tuned mass damper, or hanging ball, which takes up four stories and works like this to prevent the building from falling over and tragically crushing office workers. This 730 ton sphere looks intimidating when still, but wait until you see it in motion during the earthquake.
