Glisseo

Glisseo was the incantation of a charm that could be used to transform a staircase into a smooth slide. It was very old, having been in use since in the Middle Ages.
==History==
The sliding spell was used by the Hogwarts founders circa 993, when they enchanted the stairs of the girls' dormitories to turn into slides should any boy attempt to enter, but not vice versa, as they believed girls to be more trustworthy than boys.During the Battle of Hogwarts on 2 May, 1998 Hermione Granger cast this spell on the stairs on which she, Harry Potter, and Ron Weasley were standing flattened into a chute down which they slid very fast down the staircase in an effort to escape the Death Eaters pursuing them, their Stunning Spells shooting over them.
