There is a simple explanation for this experiment.
Water(as well as other substances) has two molecular properties called adhesion and cohesion.
Adhesion is a water molecule's ability to stock to other molecules. Cohesion is, as you'd expect, a water molecule's ability to stick to other water molecules. As long as it's wet, adhesion and cohesion of water molecules create an airtight seal between the plate, the wet paper, and the glass.
Gluing a plate to jar using air pressure differences is a pretty cool activity!!
