One of the reasons its avoided, is when the beam goes from Air to Bubble Mix, there is a ~4% Fresnel reflection going in a random direction. There is a second reflection off the inside wall as well, when the beam crosses the other bubble wall. That reflection can be an uncontrolled eye hazard. Or just become an annoying flash of bright light that is not synced to the music.

That said, large smoke filled bubbles look novel for a while, when used with very low power lasers, but can adsorb a lot of your beam energy.
