Based on the description I posted below from Matt's link I wouldnt use it for a snake. But nate check it out... it has auto detection for low water levels and will shut off.

Features: * Realistic volcano look with unique misting feature. * Creates fog with ultrasonic vibrations. * Great for adding humidity to reptile or amphibian enclosures. (Simulates cloud/rainforest). * Great for decorating model sets. * Easy to maintain: Includes safety grill and automatic low water level shut off. * Great for use with all tropical reptiles and amphibians including: iguanas, water dragons, old world chameleons, anoles, tropical tortoise species, tropical turtles plus all types of frogs, toads, newts, or salamanders. * Red LED light creates a dramatic red glow effect when volcano is in use.
