The Zero Launcher launches 2 to 6 inch diameter non-toxic fog rings that sail up to fourteen feet. With practice you'll be able to create bigger and better rings.The Zero Launcher's Fog Fluid is similar to the liquid that Hollywood uses in the movies to make safe special effects fog. Each fog ring is a cool cloud that quickly disappears at room temperature, leaving no trace behind. Also, because it is not smoke, it does not set off smoke detectors.
You'll be mesmerized by the myriad shapes you'll discover in every fog ring you create. The Launcher also provides a fascinating insight into principles of physics. Each fog ring is a rotating toroidal (donut shaped) vortex (whirling motion of liquid or air with a low pressure area in the center).
Each Zero Launcher comes with a three-ounce bottle of Super Fog-Ring Fluid, instructions and information on Toroidal Vortices. Requires 6 AA batteries (not included).
