Supercritical fluids transition between liquid and gas

So how to make them more available?

the bubble, the higher the pressure that it can contain.
So my idea is to make very small bubbles that contain
supercritical fluid. The bubbles would be made of

microbubbles cool and solidify and are removed from
The microbubbles diameter would be chosen to

The internal pressure of the microbubbles would be

The supercritical microbubbles could then be
embedded into a layer of clear resin (with the same
index as the glass).
The supercritical microbubbles layer would change
