While working at my series of modified whistles, I found a « glow-in-the-dark » whistle for bachelors (!), shaped as a cartoonesque pair of breasts.
Now, they look like another pair of something. Indeed, I filed salient little parts to get a smooth surface. Then I made a nose craddle in aluminium plate, and inserted a piece of aluminium rod to avoid air leaks at the mouth (exactly as it features on the original Nasalette, by William Carter).
Well, this is not really an elegant model and you can easily look like a pervert with it, but it glows in the dark!
And a video for the sound :
