Before Channukah comes to an official end…
If someone has a glass where there drips into it oil from above however b’shas hadlaka there is not enough oil in the glass to light for a half hour. However the oil drips fast enough that it’ll fill the cup and will indeed stay lit for a half hour and even more. Is this ok to use? Is someone yotzei the mitzvah in this way?
Also, what is the din if someone has a cup with a small hole in it and oil is dripping out, however there will be enough oil to light for a half hour.
I don’t see a problem with either case. I think the halachos of remaining lit for half an hour depend on the technical ability to remain lit for the required period of time. If at the time of lighting the lit candle ought to burn for the required time — for whatever reason — the mitzvah is fulfilled.
The only problem is when at the time of lighting there isn’t enough oil, and the person lighting relies on adding oil later. This is problematic because the mitzvah depends on the time of lighting.
If you have sources on this please add them in.
