Muggles' Guide to Harry Potter/Magic/Duro

Overview
The Duro spell turns things to stone.

Extended Description
This spell was used by Hermione to allow her, Harry, and Ron to escape pursuing Death Eaters. Having turned a staircase into a slide, the Trio passed through a tapestry at the bottom. Hermione then turned the tapestry to stone to disable the Death Eaters following; we hear the crunch as they hit the back of the tapestry.
