Okay, I'll take a shot.
The deck looked like the bottom of a pool, rainbows dancing in ever-changed shapes around MC's feet. She looked up. A glassy spehere encased the deck. The surface spun a kliadascope of opaque colors, sureally silent, like something from a fairy tale. Swarms of fish parted over it, thier little shadows flickering over MC's face.
"Oh," MC breathed. She was inside a bubble.
Okay, it's a bit dramatic, but that's something like what I would do. If you wanted, you could bring it home with childhood wonderment over blowing bubbles. Just a thought.
