Ok, I want to do a room in my haunt filled with hanging cocoon type things.
I want them to 'move'. Some could vibrate, some could just move around, I'd like some to look like something is scratching on the inside trying to get out.

I'd makybe like them to look like a bat wing covering them? Grayish black with veins showing ?
What do you think ? How could I make these ? And, do you have ideas on what to use for the movement ?

With the rise in Vampire and werewolf movies right now... I'd like to have it along those lines. I know neither of those are 'hatched' from cocoons... but who knows... maybe in my world they are!! hehe

Anyway.... I know you guys will have all kinds of great ideas on the mechanical and the creative parts of this project!
Hey, maybe even have them a little opaque and have a little light glowing in them..?

Couple of thoughts:
For the material, use black scrim. Make a wire-frame for the outline of the cocoon, and then you can stretch the material over it. Where the wire frame is seen, perhaps you can disguise it with thing like vines or webbing (all painted black) to make them blend in with the cocoon more.
Just make sure to light the cocoons from the front, so no light passes through the scrim, showing anything you have inside.

For some of the movement inside, I think a shiatsu massager could give the effect of something pushing from the inside - maybe glue a few ping-pong balls in a cluster on each rotating knob of the massager, and mount it inside the cocoon so those cluster just press against the scrim...pushing it like large fingers or something.
(a thought comes to mind on this idea - maybe make an occupant for your cocoon, and have the massager inside them for a squirming effect, and then backlight that cocoon, so people can see "whatever" is inside the cocoon squirming around)

Also, a power drill can be used to make a cocoon shudder. To make a simple off-set weight for the drill, just get a long bolt, slide a half dozen washers on it, so they slide to the end (perhaps a little glue to keep them together, and at the end). Bend the bolt near the end, and just clamp that bent end in the drill. Fasten the drill with off-set weight to the frame of the cocoon, and the whole thing should shudder when you run the drill (may have to tape the trigger to the "on" position). An on/off switch for the extension cord powering that drill will give you the chance to make it sporadic...
(probably pick up a really cheap corded power drill at a garage sale)

Lynn, I'd go with some type of vibrating motor. I bought some spider egg sack from K mart this year there about a foot long and its a mesh sack filled with white stuffing there is a battery operated motor that makes them shake seem to work well, but have not used them for an extended period. Next time I'm in the attic I'll see if I can find them amoungst the rest of my halloween treasures and send you a pic. You might be able to find them on line tool

Great ideas ! thanks. I do think I want them to look more like the bat wing thing though.

Joe, the idea of the scrim is great.. I have liquid latex that I could paint on it to give it more of a leathery look, or wing look. then add on 'veins'. The drill would be a really easy way to give it movement too. The vibrating motor would give some the look of something wiggling around...
I do want to have one larger one to look like a 'body' is scratching or rubbing the inside trying to get out. This is the one that I know I'm going to struggle with.

Terra, love your spider room in you haunt. we did one of those several years ago... but we had a real person covered in webbing lying on the floor.

Witch, that would be an easy way to give one of them movement! I have a flying bat I could do that same kind of thing to....great.

A new thought..... along the lines of the cocoon... maybe they could actually hanging bats that are curled up sleeping.. but moving around. I think that would go along more with what I am wanting in this room... but I still want to have at least the one look like its a person inside those wings.. ???

Thanks everybody! I knew this would get the ideas flowing and help me decide what I REALLY want to do.

I will do the bat idea... and have it look like something is ready to hatch from them.
Now, ..... movement. Hmmmm..
Oh, even somethings that look like in the movie Blade Trinity... where the people were in the air tight baggies. They were keeping them alive for the blood! Have it look like these bodies are keeping the hatchlings alive !!!! What do you think?
Gross or cool. I think I like that idea!

movements

A pneumatic 3/2 valve could be hooked up to an air bladder inside the prop, and with a simple timer on the valve, could be made to "breathe". put in 3 or 4 of these and trigger them randomly would look like something inside pushing it's way out. That's how I'd do it here at my shop. Drawbacks, cost and the need for an air compressor. I just hate the repeating "gear motor" type movements like cheap department store Christmass displays.

I agree with the repeating movement thing.... but I was thinking of a way to use gear to make more than one movement.... it would still be repeating but haveing more than one movement at different times would make it 'seem' a little less repeating.

I like the idea of the bladder idea. what would you use for the 'bladder' ?

ok, I realize that this thread is about a year old, but I will tell you that for a different movement for your cocoons, a hacked boobah is really the way to go. I never got around to taking a video of my spider victim this past year, but I will upload one for you. The best thing about the boobah movement is that it's different each and every time and it's up, down, and all around, so it really looks like a person struggling. As for the bat wings idea, there's a way to get rolls of somewhat thicker plastic that's not really shiny and translucent as well. I'm pretty sure it comes in a wide variety of colours. I'll try and find out from the set designer what it's called.

OK, here we go. This is my spider victim from this past year. It's a little out of context as I have removed the walls of my haunt. Anyway, here's the video:

YouTube- Victim animation.wmv

I did a quick search and came up with the right boohbah toy for as low as $7 on ebay.
