15mm Bottle Rocket Collar with O Ring Support

This is a bottle rocket launch mechanism designed to be glued onto standard 15mm copper pipe, and a take a dual pin lock / release (we used garden weed mat staples).

Has a groove for a standard 15mm O ring (e.g. for taps) to provide seal for bottle. Tested with 2.25l Lift bottles in New Zealand.

We used to make tall launchers which released from above head height to make safer.

Use / adapt at your own risk of course.
