I've actually got an old bottle of Rodinal that I've been wanting to try, but I can't get the damned thing open! Cap is stuck pretty tight.
Liquid is black as 11:59 and crystallizing as well. It was given to me by the pro I bought all my expired film from.
Not sure how to date it, but the bottle has ROAO168 printed on it.
Anyways, anybody know of an easy way to open stuck 'push and twist' bottles?
