View Full Version : Steam Injuries

01-29-2009, 10:18 PM
Last question for a while I promise.... Or do I? Anywho. I have a shower scene in my haunt design and I need to know whether or not its possible to create fake steam. I'm thinking a hazer but it doesnt have the same consistancy as steam.
Anyone know a sollution?

if you could get a fog machine to blast out the fog with more pressure it migfht be what your looking for. I would call up the guys at froggys fog and tell them what your looking for. I bet they can get the effect you are looking for with a special fluid mix.
just a thought,

Steam , real steam won't be hurting anyone after it first comes out of whatever is generating it.
The moisture level might increase in a room to the point of creating an electrical hazard though if everything is dripping wet.
Steam condenses back into water and if you are in a cold climate it could freeze to ice and make for slippery walking.
If your atmosphere is somewhat cold, hot water can make a cloud that has nowhere near the temperature that steam originates at, thereby making it much safer.

Thats the very same reason I can't use a mister. Mister would do the trick but I cant have any actual water flow because then I need drains and that means I have to go below grade and I want everything to be very easily altered for the following year.

.."would have to be below grade?"
Only the water you are trying to control has to be below grade. You could be standing on a grating allowing the water to vanish into the grate, finding the drain and going down the pipe to a sump pump that lifts the water and dumps it where you might want it to be.
(Or something like that?)

I would just use a fog machine. In the dark or low light and a strobe no one will really know the difference. Have it as one of your early scenes and the first one that uses fog. Maybe build a box and drill holes in it or use a piece of pvc cap it and have a few arms come off it and drill very few holes in it. Lay it in the tub and then when the fog goes off only a small amount escapes at a time.

We've used an ultrasonic humidifier in the past. Put a little glycerin into the tank with the water and the steam shows up way better.

Whats this glycerin your talking about? Where can I get some?

If you're simply going for the effect of steam rising from a shower, fog can do this easily and safely. Actual steam would be too much trouble since you need a boiler, plumbing, pressure releif valves...all that good stuff. But if your effect is to be more of a blast of steam, like it was under high pressure, an alternative could be CO2. Whatever you use, make sure it's well ventilated. As Jim pointed out, steam can lead to condensation. And a buildup of CO2 is not good for your guests either. Unless of course your goal is death/electrocution. Now that'll scare 'em!

CO2 is another suggestion that hasn't been made but that has way too many flags fly up. Its dangerous. DEFINATELY needs ventilation. And is flammable when built up. I think Imma stick with the foggers for now and then work from there.

CO2 is not flammable, but I think too much in a confined space can lead to asphyxiation...

It is heavier than air(but then aren't we all?) and it would fill down into a low area and kill, if you were down there.
It has happened.

You can get the glycerin from most costume/ makeup stores (Ben Nye and Mehron all make their own versions).

Yeah... or you can get it at your local pharmacy for about half the price :)

I believe the effect you ae looking for was shown at TW Vegas by Edge Design. It is a steam pipe effect and it utilizes fog. here's the link:


Is this for an existing haunt or a new haunt?
Based on your questions and some of your answers I hope you have a large budget!!
You should be spending a lot at TW St. Louis and become a favorite to a lot of vendors!!

Good luck!

This is a steam effect that we use in the movie industry. You take a tank and put a small fogger in it. You make sure it is pretty air tight. at the top is a T off. A compressed air hose is attached on one end of it so that the compressed air will mix with the fog. What you don't see in this photo that makes a whole difference is that there is another air line that is inside of the T Mount *Inside the opposite side that compressed air is being pumped* this line goes (Dangles) all the way to the middle of the plastic tank. This way the air goes in the T mound, Down to The tank, up through the other air line and out the other side of the T Mount. This system softens the fog and shoots more fog out Depending on the size of the air lines used and air pressure

Another cool thing to do with this system is to have the exiting line go into a pan of water (Kitchen pot). Have the line in a spiral in the pan of water with holes drilled into it every inch. This system would make the water look like it is boiling with the steam rising off. You get the bubbles and all. Its a really cool effect, Without the hazard!

That is definitely a creative idea. What size pipe usually produces the best effect (in your opinion)?

02-05-2009, 08:19 AM
I'd be hardpressed to actually know how to set that up. I understand the basics by looking at the picture but it would take me a while to match those parts in the picture to the stuff at Home Depot. So if you could post a list maybe of the essentials that would be much appreciated. If not its ok I understand.

It really depends on the effect you are going for. Lots of steam or little steam. Use bigger pipes for more output. This rigging does not need to be the same as shown you just need to get fittings that would fit to make something that resembles the ones in the photo. as long as you have a nipple where air and go in and out, and does not leak you will be fine. I'm sorry that I cannot produce a list of parts, I honestly do not know the sizes. I use whatever is lying around the shop for projects I work on, The owner of the shop is cheap.

best of luck,

No problem. Thanks for the info. Make sure the nipple doesn't leak. Vincent This Time!

In your T , does the "dangling line" go from the hose barb exit into the tank?
If so could you use two connectors? One for an inlet from the compressor, and a second outlet for the fog?

Is there a better picture of the tank? You seal the small fogger in the tank and let it constantly run?

The Mad Hatter

the dangling line, is mounted in the inside of the t and connects to the inside thread of the exit nipple, you cannot see it from the outside but it is there. and it line is about 1 foot long and goes into the tank.

the fog machine can be any size just, put it on a timer or anything. Just make sure that its inside and sealed so that no air can leak out. If air leaks it will rune the flow of the exiting fog steam.

I will do a better tutorial if I have time. I will get more photos once its back from set.
