TOKYO, Japan -- When crews demolish an old building, it usually involves a wrecking ball or an explosion and lots of dust. But engineers in Tokyo have now found a way to bring down a structure without all that noise and debris.

The remarkable feat of engineering is being used to bring down an old 40-story hotel. Going floor by floor, crews take out the beams and supporting columns. The debris is removed, then temporary jacks lower what remains.

The shrinking should take about six to seven months. It's not as cheap or quick as other alternatives, but this way is cleaner and more efficient - and doesn't disturb the neighbors.
