today and tomorrow

A Japanese firm called Kajima Corporation, developed this new way to demolish skyscrapers. They start at the bottom floor, they cut the support columns and replace them computer-controlled jacks. When they demolished that floor, they lower the building one floor and start over. You have to see it to believe it, it’s such a clean method.
They called this ‘Daruma-Otoshi’, which is a Japanese toy where you have to knock out the bottom part of some piled objects.
