Air Vortex CannonAn air vortex cannon is a device 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 meters. A vortex ring, also called a toroidal vortex, is a torus-shaped vortex in a fluid or gas; that is, a region where the fluid mostly spins around an imaginary axis line that forms a closed loop. The dominant flow in a vortex ring is said to be toroidal, more precisely poloidal.

Vortex rings are plentiful in turbulent flows of liquids and gases, but are rarely noticed unless the motion of the fluid is revealed by suspended particles - as in the smoke rings which are often produced intentionally or accidentally by smokers.
In this video Nate shows us how to build our very own air vortex cannon, which can blast smoke rings up to 30 feet away!

Battle of Suomenlinna
The Battle of Suomenlinna (also known as the Battle of Viapori or the Bombardment of Sweaborg) was fought on 7-8 August 1855 between Russian defenders and a joint British/French fleet. It was a part of the Crimean War.
British and French naval forces consisting of 77 ships arrayed for the long-expected battle on 6 August 1855. They formed into a battle line more than 3 km off shore beyond the range of the defenders' obsolete artillery.
- Three days later the bombardment commenced. It continued for 47–48 hours all the while the attacker sat beyond the range of the defenders' guns.
- The British and French bombarded only the fortress of Viapori and avoided firing at the town of Helsinki directly.
- While the bombardment caused damage to the structures above ground, including to several gunpowder magazines which exploded, the bulk of the defending forces survived unscathed with their weaponry intact leading to a stalemate with the attackers guns being unable to defeat the defender and defenders guns being unable to reach the attacker.
- Once the guns had become silenced the ships remained in the same offshore position leading to growing fears of a landing.
- However British and French forces landed troops neither at Viapori nor Helsinki, and eventually withdrew.

Toroidal Vortexes?I did not verify any legitimacy to the below images. They appear to belong to the time period this battle of Sveaborg took place. Whether these images were overlooked by the PTB, or were left uncensored intentionally, I do not know. We have what we have. This could be as simple as some bizarre artists' vision of the events, or as complicated as an unknown weapon system. Unknown to us that is... Please inspect the images, and come to your own conclusion.

The above image has a box floating in the water. I turned it upside down, and you can see it below. It's presence in the image could be an important pointer from the author.
- I found this on Moorsom's Shells so far.
The below info was written in the early 1900s. Some Galvanic or Magnetic Gun is being mentioned. Looks like in 1845 it was only capable of 40-50 feet, so who knows what they were capable of 10 years later in 1855.
KD:We have what we have, and it is what it is. Only we do not appear to know what it is. They clearly have a direction of movement, and we can see the point of origin. At the same time, these vortexes are supposed to be invisible. Yet, the artist included these toroids in his drawing. This could suggest that the author knew what he was drawing. The author in this case was J. W Carmichael.
Anyways, would love to hear your thoughts on the above.
