Q49what are the properties of a demi plane? if I place an object in the demiplane and then cast demiplane in a different space, does the object in the demiplane change location? or is the spell just creating a portal into a stable location?

also are the "walls" of the demiplane such that one cannot move past the walls no matter how much force one puts into piercing it?

A49: Demiplane is a pocket dimension 30' x 30' x 30'. The spell creates the demiplane and connects to the prime material via a shadowy door. Subsequent castings of the spell can take you to the same, already created demiplane, or a new one.

If you want to retrieve objects, you have to connect to the plane that has said objects. Where you are in the prime material does not matter in this. The door will lead to the demiplane of your choosing.

The walls are planar boundaries, save DM adjudication- nothing should be able to breach a demiplanes walls.

Q 50 Does the 'sprinkling' of holy water required for the bless spell consume an entire vial of holy water?

A50: Nope. It uses just a few drops, and technically those are not even "consumed", but good luck retrieving them and putting them back in the bottle.
