My mom bought the kids a couple of those bobble head things, [link], and it got me to thinking that I would like to make a multi headed bobble hydra, (the mythical dragon which grows two new heads for every one cut off).
Instead of just having a single weighted head swinging from a hook inside the collar of the body, each of the hydra's, oh say, five heads would bobble from it's first neck segment, which would bobble from the next neck segment, Which would bobble from the next segment, and so on till finally the whole thing would bobble from a very heavy paper weight of a body.
The slightest breeze or a light tap would cause all of the heads to slither around independently in a snake-like fashion.
A stupid novelty perhaps, but one I haven’t seen baked.
The bobble cobra would be pretty cool too.

Seven-headed Bobble Hydra [jutta, Nov 05 2004]

Looks like the Harry Potter people are on their toes after all Jutta. [2 fries shy of a happy meal, Oct 04 2004, last modified Oct 05 2004]

How about a head-bobbling crash test dummy to place in the front seat, to respond to conversation? Brake repeatedly and it nods; swerve from side to side and it shakes its head.

Nice, fry. i'll take my sister's bobblehead, mutate it, and leave it in her room late at night...using Evil Technology, of course.

OK, now I get it. This is good, but it would be a challenge to make, since the center of gravity of all the segments above each hook would have to be under that hook's level. Otherwise, the whole column would just droop instead of wobbling.

Yeah I thought about that. The weight mechanisms would have to be adjustable. If the opening for each had enough clearance, then the individual neck segments could be positioned at almost any angle and would return to that shape when it stopped bobbling.

I also thought that you could make one that harnessed the heat from an interior light bulb or candle. The escaping heat could be directed out of each neck, making them continually sway.
A spring which uncoiled when close to the heat source would cause the wings to extend, and lower, pulling the spring up and away from the heat, which would make them retract, bringing the spring back to the heat.
To make them appear to breath fire, small filaments of something like crate paper could be connected to a miniature crank shaft, (heat driven), and run up the length of each neck. The escaping heat would make the flames flicker and the reflected light would cause them to glow.
Cut a small slit for each scale and they would glow as well. It would be cool night light.

I'll buy one :)

Very, very good. Including the excellent bootie star. I wonder if the heads are all weighted similarly? I hope this fine hydra gets to glare barefully out the rear window of your car.

Nicely added illustration, [jutta]... and superb papier mache creation underlying image.

How'd I ever miss this? That's a great sketch and sculpture.
