the 3-D glasses for shows like Philharmagic or Bugs Life are reused right? im assuming they are since they collect them in a bin after the show and i cant imagine them just throwing the glasses in the trash. but the real question is do they clean these glasses in any way or are you wearing the dandruff and sweat covered disgustingness of the guest who wore them before you? kinda gross if you are. and i am by no means a germ freak but this definitely cant be sanitary. people have rashes and stuff. great shows though. enjoyed them both alot.
