smoke fluid

[Anonymous]

Has anyone had any luck with homemade smoke fluid? I've limited info regarding original manufacurer's use of mineral oil and propylene glycol. Got both at work and tried them. Mineral oil isn't as good as the original's and still playing with propylene glycol. Seems to be working good, better smoke than original's at first and equal towards the end. Haven't tried adding any fragrances yet. Anyone have any additional info. [e-mail]

What would happen if you dropped a piece of coal into the little stack ? or coal dust ?
