When the passengers enter the valve-controlled water balloon launch cabinet sending people down at fast pace, their hearts began hanging in the air. Passengers face forward, their arms crossed before their chests and the audience beneath their feet. When the final countdown begins, passengers’ hearts beat faster and faster. 3…2…1, the shutter opens to drop the passengers, who in free fall motion by the acceleration of gravity as speedy as up to 10 m/s, fall into the 360°water loop chute like crazy with the greatest momentum! The strong impact and appeal, and constantly attract tourists repeatedly.
