Wait…….if the bag is bottomless, and you tear open the side of the bag from the opening, downwards…………….

If you look inside of it, you see all the stuff in a huge hole. if you watch the hole as you tear it open, that hole shouldn’t shrink, if your tearing it open. So the stuff should stay inside right? So more space is added to keep that space where the stuff is added….ripping the bag open several times increases its opening size over and over again.

no, it has the same mechanics of a normal bag if its ripped, stuff starts falling out, i just read the description of the bag of holding in the DMS guide

it all falls out
Technically….it goes into the astral plane…..so what if someone goes into the bag of holding, holding a bag of holding, tears the bag of holding their inside of, and brings the bag of holding their carrying, with them inside the astral plane…then they tear the the bag of holding their holding in the astral plane, creating a second astral plane?
walk into the mesa and try and find something interesting
