I asked because I was in Manhattan about 3 or 4 years ago browsing in a discount store and they had a "Harry Potter Nimbus 2000 Broomstick with realistic noises" (I'm not quite sure what noises a broomstick makes) but on the box it had clearly stated in large letters "CAUTION: Broomstick does not really fly"
OMG! They are ADORABLE! My little brother has a batman suit that he wears to bed almost every night, I'm not looking forward to when it doesn't fit him anymore
