Need Feedback: DIY Smoke-Breathing Witch Cauldron built with fog chiller & amber LEDs
Hey everyone! I've been prototyping a giant 45-gallon cauldron prop that sits between my 12ft Skelly's feet to look like he's stirring a witches' brew. **Materials Used So Far:** - 45-gallon plastic drum cut in half with rolled foam lip - 800W low-lying fog machine routed through an inline PVC ice chiller - WS2812B addressable LED strip pulsing fire embers (orange/magenta hue) - High-density upholstery foam carved with heat knife for bubbling skull stew **Questions for the group:** 1. Does the mist dissipate too fast in open air? Would adding a low-RPM inline computer fan help force the smoke down to ground level? 2. Has anyone waterproofed WS2812B strips for damp foggy environments? What silicone sealant holds up best against condensation? 3. Should I add a motorized stirring stick anchored to Skelly's right hand, or would wind gusts snap a 6-foot PVC staff? Would love any thoughts, critiques, or safety tips from folks who have rigged fog near their skeletons!
