More than 10,000 people have set a new Guinness World record for "human dominoes" in China's Inner Mongolia, toppling a record set a decade earlier in Singapore by more than several hundred.
The 10,276, mostly students seated cross-legged and falling backwards in a line that snaked across an enormous square, took 1 hour and 20 minutes to set the new record on Thursday.
"The human dominoes were a success. The new record is 10,267 people. This is a new Guinness World record," Guinness' official Wu Shaohong said, in images broadcast on state television.
The ceremony in the Inner Mongolian city of Ordos kicked off with Chinese basketball star and former NBA player Mengke Bateer passing a basketball to the first domino in line, who then all fell backward in turn.
The participants trained more than four hours each for three days in preparation for the event, China's official Xinhua news agency said.
Previously, the human domino record was held by 9,234 students in Singapore in 2000.
