Olfactory Airs - industrial odors for use on model railroads - liquid that you spread around the layout to make it smell just like the real thing. Here is a sampling of the available odors:


Noticably absent is GERN flux.

I just noticed that too. You are aware that, like the secret recipe for Kentucky Fried Chicken and Coke, the formula, including it's unique odor, for GERN flux is patented and held closely under wraps by those responsible for its safekeeping. A few have tried, not everyone succeeded, but I did find this little note hidden in someone's blog on the Internet:

Although the GERN flux formula is protected, we have found a way to mimic its unique odor using the Olfactory Airs products. Here it is:

One oz of #701
One jigger of #713
A dash of #750
Two oz of #721
One ladle of #730
1/2 cup of #743

Mix ingredients well and place in a dark, damp location, uncovered for at least 14 days to allow to ferment. Us as you would any other Olfactory Airs odor products.

I think there have been efforts by GERN to shut this site down, so I'm not going to give you a link or the blogger's name.
