A new world record for a domino-style display has been set at a toy fair in Japan.
17 people worked for over 18 hours to set up the formation of 10,000 wooden sticks in a chain being set off.
Takaaki Hama, the man in charge of the record-breaking display was delighted.
He said, "Maybe someone else will break our record, and then we might break it again and keep going."
