Log 16 FAE and Thermobaric explosives
This log isn't going to be that in-depth as most of my knowledge about these weapons comes from YouTube. YouTube is a fun video-sharing platform primarily for entertainment.
One can't expect people making easy-to-digest videos to go in-depth on these topics. Especially If I saw the results of the explosions on people in videos it would have made me lose my lunch in my past life.
Many times I have learned about this type of stuff due to large tragedies. F*** That reminds me of the 1919 Great Molasses flood
That would be a great high-viscosity water Jutsu I will have to write about in a future log! I mean what is better at being in logs for combat skills than things that have successfully killed a lot of people?
Thermobaric weapons apply the same principles that cause things like dust explosions. If you haven't seen this, basically it is a dispersal of a flammable droplet or dust like flour that ignites.
More precisely, a thermobaric weapon also known as an aerosol or a vacuum bomb is a type of explosive that uses an initial explosion to disperse an aerosolized cloud of a gas, liquid, or powdered solid explosive.
It is then this heated cloud ignites at such a speed and over such a large volume that it produces a pressure wave. However, there is a limited oxidizer available so after the initial fireball pushes away the oxidizer with its explosion and deprives the initial striking point of air.
A second pressure wave of air moves back inward into the vaccine mood superheated fuel just looking for more oxidizer. This air will fuel additional explosions prolonging the detonations and causing more damage.
This is different from more conventional explosives in my world where the payload of the explosive is a mix of fuel and oxidizer so all it needs is heat to create the iconic ball of fire.
However, as this explosive requires the atmosphere as an external oxidizer, adverse environments reduce the effectiveness or can straight completely suppress this weapon if the conditions are bad enough.
Vise versus the Weapon destructive capability is even greater in confined locations or enclosed spaces.
This weapon is uniquely good at killing targets in let's say unpleasant ways. As I mentioned before the pressure wave produced from the rapid oxidation of the fuel and the subsequent reoxidation of the explosion's radius creates a multitude of pressure waves.
Pressure waves due to the fact they travel through a material as a wave are great at rupturing internal organs like the lungs. If the fuel does not explode but only catches flame for whatever reason the burn fuel will still cause severe burns. If none of the fire burns then if you used a poisonous fuel the fact it is aerosolized it will be inhaled and be a highly toxic hazard possibly leading to death.
Examples of injuries recorded in my world with FAR explosives within its optimal blast zone (a confined space) are Those near the initial blast point obliterated. Those at the fringe of ground zero are likely to suffer more internal injuries like burst eardrums, crushed inner ear organs, severe concussions, ruptured internal organs, and blindness.
The worst part is that they will usually not be rendered unconscious by the blast, but instead suffer for several seconds or minutes while they suffocate.
I remember reading this stuff on Wiki after watching a video on YouTube. The fact they had to censor this info on the video platform was sad but understandable.
Just wow imagine getting blown up and left laying on the ground world silent, coughing up blood unable to pull in any air as all of it was used to fuel the bomb that has been blowing up for the past 20 seconds. Just FUCK! Kids watch out for who you subject this concept to.
Basic weak application
I advise collecting a seal and filling it with flour or sawdust and two explosion seals. One weak explosion to spread your fuel and a second to ignite this Fuel. Sawdust is best as it is cheap and easy to acquire in the land of trees. Dust is also due to its small size and the square cube law means its small volume is inversely proportional to its large surface area.
As surface area is needed for a fire. The surface allows contact with air which provides oxidation required for flames. The finer and smaller the dust the faster the fuel will burn and the hotter the flames can become.
A quick example is a 1 kilogram (2.2 lb) sphere of combustible material with a density of 1 g/cm^3 that would be about 12.4 centimeters (4.9 in) in diameter, and have a surface area of 0.048 square meters (0.52 sq ft). However, if it were broken up into spherical dust particles 50 μmin diameter (about the size of flour particles) it would have a surface area of 120 square meters (1,300 sq ft).

I will explain how I believe fuinjutsu works and how intent might effect it.
