So, this Rube Goldberg contraption is a prototype draft tube humidifier for my hatcher. Advantages: control humidity level by placement of the hose further in or out of the fan airflow. Easy to refill water reservoir. No mess. No hot, wet sponges or pads.
It's just a cheap pond mister in a canning jar, a funnel, a piece of tubing, and some water. Simple is good.
