What is the real size of a hydrogen bomb explosion?

Famous tallest buildings VS hydrogen bomb tests. We all know that the nuclear explosion is enormous, but it’s hard for us to grasp the real size of it. This video compares three explosions of hydrogen bombs of different yields to the 146 m tall Great Pyramide of Giza, the 330 m Eiffel Tower, the 443 m Empire State Building, the 540 m Ostankino Tower and the 829 m Burj Khalifa - the world’s tallest structure. I used archival films of Soviet nuclear tests, digitized in high resolution. The video is made for educational purposes.
