These daredevils in Yixing, in China's Jiangsu province, put on quite a show on Monday while suspended many metres above water.
The sport, known as flyboarding or hoverboarding, involves being strapped to a board and propelled upwards using the thrust provided by water pushed up a long tube.
Flyboarding has been gaining popularity around the world in recent times.
Last week, GBTimes reported that Mr Liu He of Beijing set a new Guinness World Record by completing 29 water jetpack backflips in one minute on Baihe lake in China's north-west Shaanxi province.
In doing so, he broke a record he had set in August last year when he succeeded in performing 27 backflips.
Last year, a group of 58 people also set a new world record for the largest water jetpack flight formation in the city of Cavalaire-sur-Mer in the south of France, added the same report.
