Okay, my friend Grace does Tinker Bell for the Fireworks. Tink is indeed a living person in costume. She wears tights, a green leotard 'skirt' her wig, and the wings. The wings are actually the only part of the costume that have lights on them, everything else , well thats a 'Disney Secret.' She is suspended from an angle on Cinderella's clothesline" which uses a whatchamacallit that is hiddedn by her wings and rolls her down the clothesline. Backstage, its pretty funny to watch. When she starts, you actually need to hold her legs so she is angled correctly, then you unstrap her so she can 'fly.' When she lands they make her eat...like I said, its funny backstage. Just remember, this is all a 'Disney Secret' so shhhhh
