Enjoy the scents and sights of Halloween with the Aroma Brew Witches Cauldron Essential Oil Atomizer. Simply add your favorite scented essential oil, water, or heck even an Alani Witches Brew Energy Drink and watch as spooky fog erupts like a real brewing cauldron. One will need to purchase a Ultrasonic Atomization Module Ultrasonic fogger DIY Humidifier with PCB (recommended 5V) with a disc diameter of 20mm. These can be cheaply purchased. Glue circuit board to the cauldron plug platform and insert the atomizer disc through the slot of the cauldron and then gently press the plug into the slot. Simply add water or scented essential oil to platform in the cauldron. The ultrasonic disc should just touch the surface of liquid to work.
