I ran four fog machines for three different scenes at my yard haunt this year. I saw that they sell fog scent and thought this would be perfect for each scene so I purchased Swamp for my pirate ship, Electrocution for my electric chair and Haunted Mansion for my haunted walkway. I purchased these from HalloweenFX.com and would like to say that I can't recommend these products to anyone. All the smells were extremely similar and none smelled like what they were supposed to. In fact, everyone kept saying how nice my fog smelled and that it was like walking into a bathroom with potpourri. NOT WHAT I WANTED! The only smell that actually worked like it was supposed to was Charred Corpse from Froggy's. This was placed in the fog machine for my cryo chamber corpse and smelled nasty, just like I would expect from a charred corpse. Anybody have any better experience with fog scents such as Froggys? Don't want to spend the money again next year if Froggy's is mostly a disappointment too.
