My hoodie takes longer time to dry. Hypothesis rejected.
However, there's still hope. The process of freeze drying isn't just freezing and drying. One have to reduce ambient pressure during drying.
Vacuum seal bag. That space saving thingy.
My new hypothesis, vacuum seal my hoodie in the vacuum bag, put it in the freezer and dry as usual. That vacuum bag alter the pressure. Sucking out air makes the atmospheric pressure greater than the pressure in the bag. Hey, isn't putting it inside the vacuum bag lowers the pressure.
New hypothesis no 2. Freeze the hoodie, dry by putting it in the vacuum bag...
Now I'm confused...
