Aqua Star is an absolute sensation in the field of water rockets:

A complete system with almost all standard PET bottles
without using adhesives or tools for water rocket can be converted!

up to 100m fly high with water and air!

Aqua Star is a completely new and sophisticated approach which it has previously not been so.
A rear section that adapts to most bottle necks, a soft, aerodynamic foam tip which conforms to all bottles diameters, and, furthermore, provides space to give, if necessary ballast in the tip.
The launch pad is sturdy, tilt-proof and can be folded compactly for easy transportation yet. The special water rocket essay provides the rocket safe guidance during startup.

The kit contains everything you need:

There are only still a standard bicycle pump and empty PET bottles
needed by carbonated beverages. Disposable PET bottles.

It has deliberately avoided the addition of PET bottles because it is already enough of them are in the world.
Therefore, one can give a commercial bottle a second career as a rocket before it is disposed of!

After the missile was put together, simply fill the bottle about 1/3 with water lock on the launch pad and apply pressure with the bicycle pump.
Then set the pump aside and pull the trigger on the connected trigger,
which unlocks the rocket.

The missile can be launched in the open only under adult supervision in order to avoid possible dangers. Safety warnings. For security reasons, only one-way PET bottles may be used.
