The idea behind this water rocket design is to create a time delay for the release of some of pressurized water to increase rocket travel distance. There are three chambers of pressurized water that each have three different nozzle diameters. The outermost chamber has a nozzle diameter of .844 inch, the middle chamber nozzle is .535 inch, and the inside chamber (which holds the largest volume) has a nozzle of .400 inch.
