View Full Version : A Grinding Scene

08-18-2007, 07:43 AM
Last night I was in my haunt doing some things and I saw a nail/screw sticking out of the wall .. A couple of them actually. I then went and got a grinder and started to grind the tips off... As all of you know, this sends off major sparks!!!! At this point I scratched my head and said to myself.... "dang, this would be a good scene" especially in a real dark room where no lights are used. When the group comes by, the sparks fly.... MY QUESTION >>>>>>>>>> To you guys are.... Has anyone done anything like this before? If so, how was the scene done, and what cautions were taking?

I did something like this a few yaers ago. Right before they exited the haunt I built a latform over head. I cut a square hole in it apox. 2' x 2'. I placed a piece of steel grating over the hole. Then attached a piece of plexiglass under. As soon as the customers got directly below we rand the grinder over the grating. They hit the floor every time!

You could do the same things from behind a wall that they walk next too.

Hope that helped,

Hey. I looked at your website Deadly Intentions and you have a scene wit allot of blood and gore... My question is what did you use for the blood and stuff that did not stain the hands, etc?

We did something similar, except that we had our actor behind a plexi window grinding and thowing sparks towards it. Use rebar, it sparks more than anything else I have used.

We use real pigs blood! Just kidding. Usually Steins stage blood. It stains. Almost anything stains. You just have to find an actor that doesn't care if they turn a pretty shade of pink in October.

sparker cage, battery charger, metal , tape, more metal, maybe some decent wire,this one actor even rigged his saw to throw sparks

The safest way to make sparks is to take some welders flint, pieces that would be used for a torch stricker and put them on a drill. About 3 of them on a sanding disc, then you have sparks that require very little energy to create but lots of sparks that are not terribly flamable and do not give off a little spent piece of metal that could be an eyeball hazard.

Certainly add noise from what ever loud machine you want but the actual produced effect is safe.

Keep all of your spark making devices at the opposite end of the building from the napalm exhibit.
With all the lights on, in my spooky kitchen I say that this little Dixie cup has a slight electrical charge as I hand to the customer volunteer, I make a Buzz sound with my mouth and lips(versus the seat of my underware) and people jump and flinch!
Maybe you guys are working too hard to scare people?
A little pesuasive talking and a small dose of hypnosis goes a long way to accomplish much more (because I actually have invaded their minds!)

That sounds like transcranial ventriloquism. Throwing your mind? Splat, sorry folks shows over, nothing to see here move along.
