What happens when electrolytic capacitors ''dry out''?

bottle of beer drying out, only with quote marks (and without the mold). This "drying out" happens because all common* electrolytic capacitors aren''t hermetically sealed, and the electrolyte _does_ have to stay wet. Electrolytic capacitors that don''t dry out can lose their ability to withstand voltage, because the oxide layer on the aluminum gradually goes away**.
