What is the purpose of an air vortex cannon?

An air vortex cannon is a toy that releases doughnut-shaped air vortices — similar to smoke rings but larger, stronger and invisible. The vortices are able to ruffle hair, disturb papers or blow out candles after travelling several metres.

What is a vortex gun?

The vortex ring gun is an experimental non-lethal weapon for crowd control that uses high-energy vortex rings of gas to knock down people or spray them with marking ink or other chemicals. The concept was explored by the US Army starting in 1998, and by some commercial firms.

What creates an air vortex?

The difference in air pressure between the fast-moving air inside the vortex ring and the slow-flowing air on the outside of it makes the vortex spin, keeping it stable while moving through the air.

What does a vortex?

1 : something that resembles a whirlpool the hellish vortex of battle — Time. 2a : a mass of fluid (such as a liquid) with a whirling or circular motion that tends to form a cavity or vacuum in the center of the circle and to draw toward this cavity or vacuum bodies subject to its action especially : whirlpool, eddy.

How does an air vortex cannon work?

The air-vortex cannon works by quickly applying force to the air molecules inside the cup. When the balloon surface snaps forward it collides directly with the air molecules inside the cup, pushing and accelerating them toward the hole at the end of the cup.

How do you shoot smoke rings?

How to blow smoke rings

Step 1: Draw a mouthful of smoke from your hookah.
Step 2: Press your tongue against the bottom of your mouth.
Step 3: Shape your cheeks and lips as if you were sucking on a lollipop, and open your mouth to form an ‘O’ shape.
Step 4: Click your lower jaw forward to blow a smoke ring.

How does air vortex cannon work?

Does vortex increase lift?

The presence of a stable leading edge vortex (LEV) on steadily revolving wings increases the maximum lift coefficient that can be generated from the wing and its role is important to understanding natural flyers and flapping wing vehicles.

How can I make a vortex cannon for Science?

Build a vortex cannon and discover how fluids (liquids and gases) can move in unique ways due to their physical properties. Sheet of plastic large enough to cover the large opening of the garbage can (a plastic garbage bag will do) A bungee-type cord long enough to TIGHTLY seal the plastic sheet over the large opening of the garbage can

When did William Thomson make the vortex cannon?

In 1867, William Thomson (later to assume the title Lord Kelvin) gave a presentation to the Royal Society of Edinburgh** in which he proposed that atoms (whose inner structure and nature was at the time unknown) are in fact complicated vortex rings circulating in an aetherial “fluid”.

Can you trap smoke in a vortex gun?

Dr. Thomas suggests that it may prove feasible to trap the smoke of a manufacturing plant in huge vortex guns just above or below the roof. Powerful automatic hammers would strike the guns at periodic intervals, and the smoke would be sent into the air in the form of vortex rings.

What makes a ring of air come out of a cannon?

The “ring” of air that shoots out of the cannon is actually a flat, vertical section of of air. The outer edge of this moving air is rolling backwards on itself. This vortex of air is generated because the air leaving at the center of the hole is traveling faster than the air leaving around the edge of the hole.
