Water rocket valve/nozzle

  1. Oct 5, 2006 #1
    Can someone please explain how a water rocket valve will work. i know you could use a cork and a tyre valve as a very simple design with the bottle opening being the nozzle shape. but what are some other valves that ensure the bottle is pumped to the maximum pressure it can hold (a cork will most likely be forced out before maximum pressure is reached. and what could be a method of attaching a nozzle as well?

    See:my construction article including links to Clark's site and others.

    The basic mechanism:
