Slinky mermaid figure, that moves
around, with hair
swirling, amongst the gently rising and
sinking blobs of melted wax, inside your
lava
lamp.

My girlfriend is a mermaid. Not sure she herself would enjoy swimming in melted wax, but she'd like this ornament. [+] |

For those with more macabre tastes, you could make it a normal figure, looking like a drowning person. |

How about a little Pompeian girl? |

... or a freaked out looking hippie. |

I'd buy the hippie version first, actually. |

Reminiscent of the popular elementary school science fair demonstration "cartesian diver" - which sinks or floats based on external pressure. [link] |

I can remember our old lemonade
bottles having a large screw top
stopper, which sealed in place with a
red elastic ring. You could buy a toy
diver, which you placed in the bottle
filled with water. When you screwed
down the stopper he sank, and when it
was relaxed he rose up. I also seem to
recall a diver with a cavity that you had
to fill with a tiny amount of baking soda
to make him work,.... |

Ahh... the baking soda divers. I had a submarine like that, and got hours of diving-surfacing-scaring the hell out of my fish-enjoyment when I discovered that i could operate it without the baking soda if I just let the bubbles in my aerating aquarium power filter stick onto it. |
