Absolutely stunning!!! That just might be the coolest thing I've ever seen. I have a tinny little remote activated fog machine (purchased at Target) that I cover up with fallen leaves and shoot it across the sidewalk at unsuspecting trick-or-treaters. It's entertaining and gives them a good scare. But holly crap...it's nothing on this level!

I'm embarrassed to ask this (to anyone I guess), but what's the science behind pumping the fog through that "ice box" first before it shoots out the other side of the crypt? Does that make the fog thicker by pumping it through a chilled PVC pipe first...compare to just shooting it straight from the machine? I need a halloween props for dummies book or something.

Much appreciated.

basically, your pumping the hot fog out of the fogger into a cold environment (chiller) which cools the fog down rapidly causing to thicken up some but more to the point causing it to be colder then the ambient temperature and laying down on the ground (ground fog) instead of wafting up into the air and dissapearing. The type of fog juice you use has a lot to do with the effect your going for, heavy thick fog juice will obviously be thicker but it will hang around a lot more so as the fog warms up it will start to float in the air and could fog up the whole street, if you use a fast dissipating fog then it will come out thick and lay on the ground and as it starts to warm up it dissipates in effect keeping the ground fog illusion.

hope that helps

Yes, thank you. Looks like something I can experiment with and see what works best. I appreciate it.
