About this model
This is our take on the classic "Tornado Tube", used for joining soda bottles together to create huge water rockets. A short video about this design can be viewed here: The "tornado tube" name comes from a science toy used to connect bottles together to create a vortex when water moves from one bottle to another. Water rocket builders quickly seized upon the science toy and repurposed it as a water rocket coupler. However, the science toy version is notorious for leaking pressure and also known for choking the flow inside the rocket. Our design uses an external o-ring seal on each end, which we discovered when designing our Gardena water rocket nozzle (you can find it among our other things). This creates an unrestricted flow between bottles for optimum performance. To use this design, you…
