Frequently Asked Questions

The assembly is very simple – just watch this video

Or follow the picture instructions below:

A large open space is recommended, like a playing field. You should allow a radius of at least 50 metres (164 feet) around the Water Rokit launch area, as on a windy day the Water Rokit will rarely land close to where it took off from. You must also ensure it is safe to launch the Water Rokit – you must not launch it in a densely populated area and you must never launch your Water Rokit near overhead power cables or similar obstructions. Be aware of nearby trees so as not to lose the Water Rokit on its descent. Be mindful of other people that may be in the area or within the Water Rokit landing zone area.

You may be using too much water in the Water Rokit. For optimum use we recommend to fill the carbonated drinks bottle to approximately ¼ (one quarter) with water. Over filling will make the Water Rokit too heavy for launch, causing it to turn sideways. You should also check to make sure the Water Rokit is placed on a firm and flat surface pointing vertical when launching. On a windy day the Water Rokit can be blown sideways. 

For optimum use we recommend filling the carbonated drinks bottle to approximately ¼ (one quarter) with water. Over filling will make the Water Rokit too heavy for launch, causing it to turn sideways. Under filling the Water Rokit may mean its flight time is less, meaning less height is achieved.

Any good foot or stirrup pump with universal connections will work.

Yes. It’s best to use some household rain water gutters, and adapt it as a launch system. Household gutter is a good material as the carbonated bottle fits comfortably onto this, reducing the friction upon take off.

Under normal operating conditions the Water Rokit will fly to around 30 metres. At around 25psi, the black rubber nozzle is designed to expand, allowing the brass plug on the yellow pressure tube to be automatically ejected. It is the amount of pressure build-up that ultimately determines the acceleration of your Water Rokit, and thus the height of flight achieved. You must not modify the Water Rokit in any way to make it fly higher, as it has been designed to work safely at the pre-determined pressure settings. Modifying the Water Rokit could damage the product, and be dangerous to the operator and spectators when using the Water Rokit.

To protect the screw cap if the Water Rokit lands on a hard surface, like concrete. Without the ‘o’ ring, the shock wave may break the plastic screw collar. All plastic components are made using tough and flexible materials.

You need to assemble the fins correctly as per the instructions. Correctly assembled, the fins should never fall off the Water Rokit during flight.

You need to assemble the rubber nozzle as shown in the diagram on the instructions. It has a groove around its body which must clip into the plastic screw collar. Correctly assembled, the rubber nozzle should never fall off the ​Water Rokit during flight.
