Proxivapor

Toba scientists exploring Proxima Twilight noted centuries ago the strange multi-colored aurora on that moon and investigated the cause. The mystery was soon solved: the volcanos of Proxima Twilight release a strange chemical brew, which includes water vapor, neon, and various organic gases, all of which rise into the atmosphere for Proxima Twilight, where they are energized by incoming cosmic radiation, and then form into strange twisting ribbons of color.

The Proxivapor replicates this effect. It is, at a basic level, a spray bottle with a button on top that, when depressed, expels a cloud of gas (compressed.)
