Circuitry Ideas (Help me scare the crap out of "ghost hunters")

Ok..

First, thank you for even reading this post, as I know I am not a regular (infact I don't recall posting here ever before, though I might have). That being said.. onto the details.

A local message forum of car ethusiasts were chatting about local "ghost/haunted sightings"... and long story short, have decided to visit a particular "haunted" place at a particular time on a particular day to "hunt some ghosts.."

I'm looking for relatively inexpensive ways to achieve operation, "make ghost hunters crap themselves..." Who's with me?

I was thinking simple things such as yellow LED's (not the superbright clear type) glowing when fishing line is "tripped" (removing a piece of plastic between two metal poles, thus completing the circuit type of thing) to give the appearance of eyes (but would be nice to throw on a sound circuitry as well which would give a "shhhhhhewwww" type of sound or something else half believable)... but staying on continuously is definitely NOT a good thing.. so a timed circuit in which the "shhhheww" sound (or whatever) would play, end and the eyes would be lit for a total of maybe 10 seconds...

I'm no electrical engineer at all.. however, I have made my own PCB's and following circuits from Electronics Handbook (when it was around and if it still is then no one carries it around here) and I solder/desolder quite often. In other words, I'm not intimidated at all by following a schematic and building the circuit.

I have three wireless 9v driven camera's (spy cams) already, which I plan to utilize as well in hopes to get videos of these "ghost hunters" hopefully getting the crap scared out of them... which of course would expeditiously made into a MPG or AVI for all of you to view.. :) My way of saying, "thank you for your help"...

Also, any ideas are welcome as well... I would LOVE for this to be a "success" (for US that is..)

TIA!!!

Sorry. I should have been more precise, I wrote this in a very fast manner anxious to start receiving replies. :)

The cameras are just 2GHz cameras that run off of a 9v battery (I will probably run them from 4 D cell batteries to ensure it has plenty of power to last the entire evening). The receivers also run off of 9v and have only a video composite output (no audio feed of any kind on these). The "place" mentioned is in the middle of a forest more less.. so only a laptop can be used.. I'm not sure how I will go about collecting the video feeds, but, I'm working on that as they aren't wifi (the 2ghz is a proprietary signal frequency, no 802 standards here) and they don't have Bluetooth either.

As for the "metal poles" I suppose I meant metal leaf's basically a piece of plastic wedged between two metal contacts, the plastic piece attached to a fishing line with its other end tied to a tree, so when tripped, removes the plastic thus completing the circuit as a result of the two metal contacts then coming into contact with one another.

I know someone who had fun with Nitrogen triiodide. A few drops on the floor and allowed to dry overnight created a few surprises... but you shouldn't mess with that stuff it's dangerous.
