Question:
Can someone rip aluminum foil from a roll on shabbos, or is it best to pre rip it before shabbos? LECHATCHILA OR BIDIEVED
Answer:
Aluminum foil should not be ripped on shabbos, not L’chatcila and not b’dieved, and it must be pre-cut before shabbos. The reason is because ripping the foil is korayah, and also it is making the foil usable and considered makeh b'patish.
Best Wishes
