The quest for 300 psi

George Katz updates us on his experiments with fiberglass-reinforced PET bottles.  It will be cool to see what his big and complex water rockets can do when pressurized to 300 psi. He recently reported a personal record of 810' on his clustered and staged Acceleron V at a mere 120 psi.  He estimates that 30 of the extra psi is needed just to compensate for the weight of the reinforcement.  As usual, he provides data and photos.  And warnings about testing at those pressures - he tests inside an old scuba tank (see attached photo)!

On another note, he has acquired a LOC/Precision Weasel 'pyro rocket'....
