Help with Floating swamp shack

[thehauntgr]

On one of my past haunt tours I vaguely recall one indoor attraction having a floating swamp shack. It felt as if it had a slight "4-way" floating action as you walked through; not enough to make you stumble, but enough to recognize the motion. Maybe it was controlled by air bags on the 4 corners???? I want to say it was at The Darkness (Larry??) but I can't recall for sure. Visit too many attractions and forget to take notes, duh! Does anyone have any insight on this? Plans...mechanics... size etc?
Thanks!

It was the Darkness and it's on suspension springs in all 4 corners.

Its not on suspension springs its on air bags. The entire floor was made from steel and from there the air bags move it around.

We did a similar effect using a suspended floor. We had a building with a mezzanine over one area. We used 500# test chains (I think 6 or 8 of them) attached to the I-beams above and the moving floor. We built a frame around it so that it couldn't move more than a few inched in any direction.

I like the idea of air bags as it would probably give a spongy feel, too.

Larry, how do you protect from any trip hazards?

Hey Jim,
Check your PM's...I think I have what you need!

In the VERY OLD Darkness we did another FX just like it and I'd have to draw you a picture and post it but... we did everything with chain. Imagine a frame that is just bigger than what you are trying to float, and that frame has poles that go up especially in the corners. Then you put giant i bolts in the frame of the thing you are trying to float and that chain goes up to the top of the steel frame you built around it.

So in other words the chain goes from the bottom of the floating room to the top of the outside wrap around frame. So now its suspended off the floor and moves very easy in all directions. You could move it by hand, with an air piston or even just with people walking around inside of it. The floor only needs to be an inch or two off the floor that is it.

Very easy to do.
