Yes you can trap light in a pot.
If some photons entered said pot, and you were able to close it before they escaped (possible), they would remain in that pot. If the interior of the vessel was "perfectly" reflecting, those photons would continue to bounce around inside the pot until the lid was removed. Having a "perfect" vacuum would be necessary, since the interaction of the photons with any molecules in the pot would eventually reduce the energy of the photons. Even one atom of matter in that pot would interact with the photons, so they would eventually lose their energy as heat (lower energy photons!). One atom of matter in even one cc of space is a level of vacuum we have yet to reach, here on earth.

If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
