In summary, The conversation is about a vortex generator, specifically about how it works and if there is a way to make a homemade version. The person also asks about the speed of the projected ball and if it can work in different mediums. The conversation also mentions using your mouth to create a similar effect with smoke rings.

I refer you to

Being poor and stuff, I can hardly manage to get my hands on one of these thing. (though maybe I can twist some arms over it...)

But I wonder though... how is this thing supposed to work. Is the "ball of air" it projects simply a case of blowing wind, or is it some wave. I'm guessing that it forms some sort of solition, which can hence propagate large distances with little dissipation.

Does anyone else know? Is there a way of making a homemade version? What is the speed of the projected ball? How is it affected by wind? Can it work in a different medium?

So many questions, so little time...

you really hate google, right? :wink:

Vortex generator.

simplest "toy" to do it is your mouth: ever seen smoke rings made by smokers?

They look really fun:

1. How does an airzooka create an air vortex?

The airzooka works by using elastic properties of air. When you pull back on the flexible plastic membrane, you are storing potential energy in the form of stretched air molecules. When you release the membrane, the sudden release of tension causes the air to rapidly expand, creating a vortex of air that is propelled forward.

2. What makes the airzooka shoot air without using any electricity or batteries?

The airzooka relies on the principle of air pressure. By pulling back on the membrane, you are compressing the air inside the chamber. When you release the membrane, the compressed air is released, shooting out a burst of air without the need for any external power source.

3. How does the airzooka produce a concentrated blast of air?

The design of the airzooka allows for the air to be focused into a narrow stream. The membrane acts as a diaphragm, directing the air molecules through a small opening at the front of the device. This creates a concentrated blast of air that can be directed at a specific target.

4. Can the airzooka be used to move objects?

While the airzooka is primarily designed for fun and entertainment, it is possible to use it to move lightweight objects. By directing the air blast at a small object, you can create enough force to push it in a certain direction. However, it is not recommended to use the airzooka for this purpose as it may damage the device.

5. Is the airzooka safe to use?

The airzooka is generally considered safe to use and does not pose any major risks. However, as with any toy or device, it is important to use it responsibly and follow all safety guidelines. It is not recommended to aim the airzooka at someone's face or use it in a way that may cause harm to yourself or others.
