While the original charms corridor is a few twists and turns away, the new Charms Corridor is right here and Professor Schirmer has charmed it in a thousand and one interesting ways. For starters the walls change colour if you breathe on them (or burp or sneeze or sigh or expel warm air on them in any other way). On Thursdays, you can only walk down the Charms Corridor backwards, no matter what direction you are trying to go in. Sometimes it seems like the corridor forgets to put the doors in the right place, and it feels a bit like you're walking forever and never getting anywhere. If it is a full moon, the corridor fills with an anti-gravity mist which makes it rather difficult to get from place to place unless you have mastered the art of omnidirectional floating.

There are various flying objects out of reach above your head; these are things that got lost on their way somewhere. If a student within Hogwarts banished something or summoned something but it never reached its intended destination, chances are it has found its way here and floats near the ceiling with other lost things; an eclectic collection, keeping itself company. Many of these 'en route to nowhere' things now sport cute little wings to help them stay in the air. From eight AM, and for nine minutes every morning, the Corridor seems to forget that it is a corridor, and behaves like a staircase. It feels like you're going up or down, and so you lift your legs and bend your knees, but alas, it remains a corridor. If you trip on the stone work, it says sorry. Yes, that's right, a disembodied voice comes from the stone, apologising for getting under your feet.

Of course this means that Thursday mornings from eight until nine minutes past, if it happens to be a full moon, you'll find yourself walking backwards up or down non-existent stairs whilst floating through the air with the possibility of no doors to escape through.

Sounds like the perfect opportunity to try to catch a lonely lost thing with no place to go!

This is where you'll find the mailbox, as well as the doors (sometimes) to the charms classroom and Professor Schirmer's office. If you are waiting to see her you can sit on the floor by the Charms Office door (if its there). Don't worry, you won't get piles, that patch of stone sports a rather cosy cushioning charm!
