Hello everyone, I saw several of you @ dragon con this year. Great con I thought. Anyway, I am working on something special for next year and I need some suggestions for a steam or fog machine that can be battery powered and is light enough and small enough to fit in a back pack. I would prefer is not generate heat. I also must be low cost, like no more than 100.00 bucks. I can build if need be but I do not have any real ideas at this time. Thanks in advance.
