A "Pensieve" is a magical object that only exists in the world of Harry Potter. It is a vessel used to view or relive stored memories. With a little work, it can be recreated in the world of Muggles, as Matt Bracone did. He made a Pensieve as a wedding gift for his Harry Potter fan bride Janine that packs a lot of love into the package, complete with bottled memories, a hand-made vessel, and a magic wand. See all the components and how he did it at Unreality.
