But, as I have been told before --- it's Disney MAGIC!
A friend sent a link to a Back Stage Pass video about the stage show "Aladdin,"
https://youtu.be/B2QkcGcnpB8 and I got excited. Maybe they would reveal some of the "how to's" to accomplish this Disney MAGIC. But no -- it's still Disney Magic! Although they did give close up glimpses of the costumes and some of the contraptions under the stage. My daughter was once a performer at Disney World. She said that the performers sign a contract that they will never reveal the Disney "Magic" or even who they portray or where they will be at any time in the Park. Guess that is still in effect.
