Pensieve in Harry Potter

The Pensieve is an object used to review memories. It has the appearance of a shallow stone basin, into which are carved runes and strange symbols. It is filled with a silvery substance that appears to be a cloud-like liquid/gas; the collected memories of people who have siphoned their recollections into it. Memories can then be viewed from a third-person point of view.


Pensieve allow one to view details of things that happened even if they did not notice or remember them, and stated "that's the magic of the Pensieve, what brings it alive."
