No, it's not a special effect -- this is what happens when a stage can't hold the weight of an 80-person choir and collapses.
No deaths have been reported, although 8 of the singers were injured.
The shocking video was taken during rehearsals for a singing competition at the grand theater in Bijie, a city of 6 million in the Guizhou province of China.
The accident took place on Saturday afternoon local time; the video was posted Sunday by China Central TV.
