Monty has a nice sized storage tote with an almost water-tight seal. He also has dry ice. So could monty put glass serving trays inside of this tote and let them sit for said hours or so. See monty doesn't have a freezer big enough or not used enough to store in for anytime. BUT he does have somewhere unused and hidden that he could set this unit and leave until ready. Obviously he would see how cold this apparatus would get and seal it well (unless dry ice needed to be vented). He worries that maybe the gas from the dry ice would cause some adverse reaction to his experiment.
