What this video covers
This video breaks down the science behind fog machine fluid density by testing different ratios of propylene glycol and vegetable glycerine mixed with a standard smoke fluid base. The creator takes a methodical, Mythbusters-style approach, comparing 50/50, 60/40, and 70/30 blends to determine which produces the thickest fog output. It's a practical, low-cost experiment that gives haunters actionable data for improving their fog effects without buying expensive specialty fluids.
Key takeaways
- ◆Mixing propylene glycol and vegetable glycerine into standard fog fluid can noticeably increase fog density
- ◆Three ratios are tested (50/50, 60/40, 70/30) so viewers can replicate and compare results
- ◆Both key additives are readily available and inexpensive
- ◆Results are demonstrated visually, making it easy to judge the difference between mixes
- ◆A simple base formula is provided as a starting point for DIY fog fluid experimentation
Who this is for
Home haunters and Halloween enthusiasts who want denser fog effects without spending money on premium commercial fog fluids.
Materials mentioned
- • propylene glycol
- • vegetable glycerine
- • standard smoke fluid
- • Spirit Halloween smoke fluid
⚠ Safety notes
Propylene glycol and vegetable glycerine are generally considered low-risk, but ensure the fog machine is rated for DIY fluid blends and test in a well-ventilated area before use in an enclosed haunt space.

DIY Halloween Props - Bubbling Witch's Cauldron with Glowing Coals
Wicked Makers duo Jaimie and Jay walk through a beginner-friendly Halloween build that transforms a large plastic cauldron into a dramatic bubbling brew scene complete with glowing coal effects. The project combines an ultrasonic pond fogger for rising mist with orange string lights and textured spray-foam coals to simulate a fire beneath the pot. Despite involving several components, each step is designed to be approachable and tackled in stages, making it a solid weekend project. The finished prop works equally well for yard haunts or front-porch Halloween displays.

How to make a DIY Fog Chiller | DIY Halloween Props
Wicked Makers' Jaimie and Jay walk through building a simple, low-cost fog chiller from everyday household materials in about an hour. Fog from a standard fog machine is routed through a PVC inlet into an ice-filled plastic storage bin, where it cools and exits as a dense, ground-hugging rolling fog effect. Chicken wire inside the bin keeps the ice elevated while letting chilled fog pass through freely. The build requires no specialized tools and is explicitly designed to be family-friendly.
