I was part of the second group and we strain our glow sticks through a fine strainer into a plastic jug so not to take any chances with glass or glow sticks being accidently released. we bring the jug down, release the glow and bring back the jug, which I personally did. But there was several bare foot divers that stayed and once I released our container of glow the turned on their lights and ruined our experience which they also shined lights directly into several of our divers eyes, me being one of them. I also went in sunday morning and removed many glow sticks. not pointing any fingers but we all must try and be respectful of this, myself included.
