View Full Version : cascading fog down staircase

07-30-2012, 12:28 AM
I have a staircase built in my haunt that goes up about 6 feet in height and will be blocked off at the bottom. I have a pretty decent 400 watt fog machine that I wanted to use to create cascading fog coming down the steps. I thought about shooting all the fog in a 30 gallon barrel with ice in the bottom. Have a hole in the side close to the bottom to allow the fog to seep out. Idea is to use the barrel as a reservoir and allow a steady stream of fog to be released instead of the fog machine just simply cut off and on and give varying levels of intensity. Anybody done something like this before?

too bad the dry ice only last for 5 minutes. FROGGYS FOG has a ground hugging fog juice (I think) check them out...........best of luck with this......

The problem you will have is you wont have any pressure so the fog might seep a little but than just warm up and rise again.

I built a cooler using a large ice chest, with PVC as the intake (so the fog machine blows into it). On the inside, where the hole for the intake starts I made a wire cage all the way through the cooler to the other side. This acts as a chamber so when i fill it with ice, the fog goes through the tunnel created by the cage. On the opposite side I used a little PC fan (Radio Shack, $20) and placed it over the outlet hole to push the fog out the other end.

I usually put a dryer vent hose on the output side so I can pump the fig anywhere I want away from the cooler. For a controller, I found a remote control with timer so everything is automatic. Works really well and you can set the intensity as well as the intervals. With Froggys Fog you can get a juice made for low lying fog that works even better than regular juice. You should than be able to get the effect you are looking for.

By the way you can put dry ice in there as well and it might last a few hours depending on how many pounds you buy, but it is a pain to deal with. I put a few bags of regular ice in my cooler and it works great.

Make a fog chiller using a garbage can and dyer vent, cut a hole at the bottom of the garbage can and coil the dryer vent around the inside of the garbage can, then cut another hole through the lid of the garbage can, snake the vent up through it and attach it to the nozzle on your machine (see? now you made a pretty little shelf for your fog machine and a chiller all in one!)

Fill the garbage can with ice. Set fog timer to desired amount.

For fog juice, Froggy's Fog sells a fast dissipating fog fluid, that you can chill just like their deep freeze fluid, but it will dissipate much quicker, which should solve the issue of the fog re-rising.

Essentially, you need to find the right mix of way to cool fog down and fluid hang time. :)

If your using this for an indoor attraction use Froggys Fog Fast Dissipation Juice put through a chiller, as it would give the desired effect you are looking for.

I already have some froggys fast dissipating fog. I was more concerned about having an even output rather than spurts.

Get a Chavuet 1300 watt continuous fogger...does what it says...you wont have the spurts since it doesnt need time to recycle.

May I suggest, since it is going to cascade over a restricted area, to dampen the stair case a tad before the show or during it? I find that fog likes to linger around water before it is blown away. Also if you go with a dryer duct output for the fog I suggest attaching a grocery bag to it. Flatten it out and cut a slit opposite the fog chiller's output. It'll help keep the fog lower not to mention it'll come out more as a fan rather than just a thick flow.
