Harry Potter fans:How long was Harry's wand, if you know what I mean?
(OOTP, Chapter 1) - A silvery wisp of vapor shot from the tip of his wand and the dementor slowed.
(CS, Chapter 15) - Instead he scribbled a note to Ron: Let's do it tonight.
(POA, Chapter 12) - Something whooshed suddenly out the end of his wand.
And another one I remember was: Harry firm grip tightened around his wand.
