Challenge is to design and launch a rocket to achieve maximum range with constant pressure.
Participants are required to hit the target by adjusting water quantity, air pressure within given range and angle of the launcher.
The highest score is 100 points per launch, which will be given if the rocket hits the target point of 80 m from the launcher, or the impact point is within the range of ±1.5m from the target point (Zone I). Less point will be given if the impact point is farther away from the target point as indicated below:
