/diy/ - Do It Yourself

A thought that keeps bugging me:
If you want to make soggy biscuits crunchy again you can just put them in a fridge for a while.
As a function of producing refrigeration the air inside is also dried out, this is why vegetable crisper drawers exist: to separate the juicies from the rest of the dry air in the cabinet.

So who has some filament they dont give a shit about and can test what kind of duration gives what kind of effectiveness of moisture reduction?
