Beijing: As many as 10,267 high school students in China on Thursday formed a rectangular chain, entering the Guinness World Records for making the world's longest human domino chain.

The students from 12 high schools in Ordos City made the world's longest human domino chain in north China's Inner Mongolia Autonomous Region at the Ordos Naadam Festival that runs from August 11 to August 18, a notary public for Guinness World Records said.

In sequence, each person fell backwards and lay on the next person's legs. The event took one hour and 20 minutes to complete, Xinhua reported.

Participants wore white or orange T-shirts, and those in orange formed the shape of five characters that signified "Beautiful Ordos" in a ractangle 200 meters long and 150 meters wide.

"We practiced for four and a half hours each day for the last three days. Under the glaring sun, I hardly felt the guy behind me fiddle," said Li Xiaodong, who was the first human domino to fall.

"While lying there, I thought about a lot of things. But what I felt most strongly was the pure excitement that came from knowing I was part of the creation of a world record," said Li.

The previous record was set by 9,234 students at Siloso Beach, Singapore, Sept 30, 2000. IANS
