Magic. Look up capacitors on wikipedia!!

A capacitor stores electrical charges in its plates.

Both wrong. A capacitor stores energy as an electric field developed in the dielectric between its plates. A good dielectric with high permittivity (once called dielectric constant) concentrates this field, allowing more energy to be stored in a capacitor having the same plate area and separation but a dielectric of lower permittivity.
