General Frequently Asked Questions
How high does Hinterland's Water Rokit fly?
In normal conditions Water Rokit will fly to approximately 30 metres (100 feet) – about the height of a 10 storey building!
How does the Water Rokit launch itself?
The Water Rokit launches itself automatically, and this happens when the pressure builds up enough to release the inflationary tube which is around 25psi.
What type and size bottle is best?
You must use a carbonated drinks bottle. Water Rokit is not suitable for any other type of bottle. The Water Rokit fins have been designed to work best with 0.5, 1.0 litre or 1.5 litre carbonated drinks bottles.
What makes Hinterland's Water Rokit suitable for teaching science?
What is the most suitable age group for Water Rokit?
Any age group can enjoy the Water Rokit, but it is not a toy, children will need adult supervision. There is no upper “age limit” for the Water Rokit, though beware – it may unleash the inner child in every adult that launches a Water Rokit!
Can I re-use my Water Rokit?
Yes. Looked after properly, your Water Rokit should provide many years of fun with countless take-offs. If the Water Rokit lands on a hard surface e.g. concrete then sometimes this may damage the carbonated drinks bottle, and you may need to replace it. Spares are available separately, like replacement pressure tubes, as well as the Water Rokit tail assembly parts if these get lost.
Can I launch my Water Rokit indoors?
Do I have to use water with Water Rokit?
No. Although the Water Rokit won’t fly very high without a propellant fuel such as water. Try it and see for yourself!
Can I use any other fluid than water?
Is there a risk that the bottle might explode under pressure?
What do I do if my rocket falls over whilst pumping, with the water still at pressure?
Pick up the bottle at arm’s length and slowly undo the white top, with care, as you would with a fizzy drinks bottle that has been shaken.

Frequent questions about Usage & Assembly
The assembly is very simple – just 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.
Any good foot or stirrup pump with universal connections will work.
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.
