Who doesnt love fog at Halloween time. wannabemadsci shared this project on Instructables!
Want a tiny, completely self-contained fogging cauldron only suitable for the smallest of witches? Well, read on…
While walking through a store just before St. Patrick’s Day I saw some miniature cauldron ‘pot-of-gold’ party favors. I thought, “I’m not that into St. Patrick’s Day, but these would be great for Halloween!”
Why put gold coins in these mini cauldrons when they would be great for brewing a bubbling potion?
Then, as serendipity would have it, while looking for some electronic atomizer boards, I saw a very small battery-powered, self-contained atomizer circuit board. These atomizer boards are like mini versions of the larger ultrasonic atomizers I have used to create fog before; see my Water Only Fog Machine.
