this is the cauldron I used. and how it looks from the front with the fogger hidden inside.
the hole cut from the top and back view
the piece removed
haven't unpacked my bubble fogger yet, but is close to the same size as this fogger box
I put the front of the fogger inside the cauldron, with 1/2 sticking out the back. You may have to tip the frount up a little. I use the piece that I cut out to slant the fogger upward slightly. You have to use the small bubble option as the big bubbles are too large and slow moving they pop before they get out the top
you cant see the fogger from the front.
