Just the convo we need, bottles on shabbos.
The very simple psak- AYLOR.
I still see potential problems with this piece,
A. Why are you not still creating the cap?
B. Pushing the spikes aside/widening the ring, allowing the bottle to open should be makeh bepatish, as
@moko mentioned.
C. If the problem is with the bottle this doesn't help anything.
Still this seems to have some respectable haskamos.
