If you've ever used dry ice, you know that effect is short lived and can be expensive.

This little wonder simulates the dry ice effect using nothing but water and a nearby electrical outlet. Plug it in, put in a few inches of water and you've got a "fog" effect that floats above the water & lasts for hours. This unit turns off automatically if removed from water or if the water level drops too low, but it is recommended that you unplug it before removing it from water.

Shown here with optional splash guard.

If your mister stops operating as it should the ceramic disk can be replaced. A "Key" tool is included with this replacement disk. If given proper care, each disk can last for thousands of hours. To prolong the life of each disk avoid touching the disk with anything at any time (particularly when in use). The safety switch will shut the unit off if the water is too low in order to avoid damage, but as an extra precaution it should always be unplugged before removing from water.
