No other water rocket you can buy has a unique molded nozzle like this.
The nozzle restricts the exit flow of the water and compressed air from
the PET bottle creating a longer and higher level of thrust - just like a
real liquid rocket engine! This nozzle combined with the Q7308
proprietary launch pad creates one of the most unique and
high-performance water rocket launch systems ever! Nozzle is molded from
a tough translucent material and will last for hundreds and hundreds of
safe, fun launches!
