How To Make Thicker Fog For Your Fog Machine!

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.
