I added Sea salt to my water bottles and they take longer to freeze but they last longer too.
I have a 10 foot 4" pipe and I (electrical) Taped the holes off.
I hide my fogger in a foam crypt. and use 6 bottles in and 6 in the freezer on a rotation. of every 4 hours or so.
I also add a grate to the end of the pipe to avoid finding critters hiding or living in there.
So this year I want to finally add the unliving portrait to my haunt, however, would I need 3 separate screens for each frame? If anyone has done this can they help me an maybe show me the wiring if possible.
