ELI5: Why is tupperware wet coming out of the dishwasher, when plates and glasses are all dry?
gpt
Ceramic plates and glasses have a higher heat capacity - they can "hold" more heat, which is why they are hot when you take them straight out of the washer.  Because they're hotter, they cause the water on their surface to evaporate.

Plastic is less dense and has a lower heat capacity, so the water that collects on them doesn't evaporate as easily.
