Not sure if someone else possibly brought this up. I think I remember someone commenting about it before but I thought about it today when I was on the Carousel... add bubbles. Not overhead, actually add them from the center blowing outwards to ensure no one gets soap in the eye or soap dripping down on them. So you ride, on an underwater themed carousel, with bubbles floating around as it spins. Seems simple, reality is it would probably be a nightmare to actually do it.
