Trump World Tower

A bit like a clock pendulum, they move in the opposite direction to the building's sway, basically counteracting the motion and creating a more stable environment for those inside and also reducing the risk of damage during earthquakes.

Now, the Taipei 101 building in Taiwan and the Trump World Tower in New York both use this method.

Thank you, Michael.

So a highline feat 120 meters above Seoul inspired a dig around in the brains of risk-takers, and we've just heard how some tall buildings contain massive pendulums or have their corners shaped off to, uh, make them sway less.

Every room is old, decrepit looking right across the street.

Trump was called the Trump World Tower.

Magnificent building.

Much better.
