OK the question is how much pressure can a 1.25Ltr bottle of pop take before it goes, well POP!!

Between 400 & 600psi typically. Depends a lot on temperature and type of bottle. The smooth walled bottles perform better than faceted (like coke bottles).

When they blow, they make a loud bang - but the shrapnel is so light and encounters so much aerodynamic drag that it doesn't present much danger of injury. I still wouldn't want to be next to it.

I used to have access to dry-ice. Much fun putting dry ice in a bottle, screw the cap on and wait for the bang! The figures above were obtained using a pressure gauge on the bottle.

No size or weight limitations start up acceleration ramp can be 20seconds or more! and no breaking required. those seem a little bit on the big side for a gyro are they used in feathers or Beetle?
