A team of French scouts has built a freestanding tower nearly 19 meters high, using wooden bricks.
The construction was created beside a climbing wall to allow the four builders to keep up with its increasing size.
The Kapla blocks, which were invented 30 years ago, were borrowed from local toy libraries. The scouts used 11,000 in total.
Work stopped after three days, having beaten a five-year-old record. It took just seconds for the tower to be pulled down afterwards.
