Zero Launcher

The Zero Launcher launches 2 to 6 inch diameter non-toxic fog rings that sail up to fourteen feet. Easy to use, they are great stress busters and with practice you'll be able to create bigger and better rings.

The Zero Launcher uses the same liquid that Hollywood uses in the movies to make special effects fog. Like a snowflake, each fog ring is unique, expanding at its own rate and traveling at its own speed. You'll be captivated by their beauty, mesmerized by the myriad shapes you'll discover in every fog ring you create. The Zero Launcher will provide hours of good clean fun for children and adults alike.

A lot of how the Zero Launcher works has to do with your handling of it. There is an element of finesse you are going to gain as you improve and pit your skill against yourself and against others. The Launcher and Blaster also provide a fascinating insight into the principles of physics. The fog ring is a rotating toroidal (donut shaped) vortex (whirling motion of liquid or air with a low pressure area in the center).

Each toy comes with three ounces of Super Zero Fluid (cherry scent), enough for more than 25,000 fog rings.

The Zero Launcher has an elastic diaphram that pushes a burst of air through a small opening. You can launch fog rings holding the launcher still, but the rings will be smaller and travel a shorter distance. To create the largest fog rings, that will travel up to fourteen feet, follow the directions in the diagram below.

Note that the video above shows the Zero Blaster, a variation of this toy having a trigger, otherwise essentially the same

A vortex ring toy generates vortex rings — rolling donut-shapes of fluid — which move through the fluid (most often air, and sometimes water). A smoke ring is a common example of a vortex ring. Because of the way they rotate, a vortex ring can hold itself together and travel for quite a distance. A vortex ring, also called a toroidal vortex, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a toroidal (doughnut) shape. The movement of the fluid is about the poloidal or circular axis of the doughnut, in a twisting vortex motion.
