Alrighty then, since you have no questions and sensei has given you the run down, we'll begin. I'm going to first add onto what Lili said.

Method 1: Tangible Blasts
Alright, for the most part, the techniques within this method consist of large and powerful gusts that you exhale from your mouth or release from another point of the body or simply out of thin air. These gusts contain a few essential properties. These wind techniques can either be long lasting, forceful gusts that have the ability to blow back various items and people/animals of various sizes. These powerful gusts apply a strong pressure in whatever direction release and, therefore any object that comes into contact will be forced back into the direction essentially. If in direct oppositon (where one is coming in the direct opposite direction of the wind) or cornered against a wall or obstruction that prevents the flow, the pressure from the wind can have tremendous affects. The second type of skill these techniques may possess are blunt force. Wind that is so compressed and refined that once it makes impact with the target it creates a blunt force, almost as if it was hit with a solid object. So techniques that create compact spheres will make impact in similar a way to a bullet or if the wind is spread out a little more like a wall, it could create the sensation of a solid wall impacting, etc. On that note there are distinct ways to casting the two different types of techniques in this section.
1) For Gusts: You'll gather your fuuton chakra through your body to the point of release and then you will release a steady, fast, and powerful gust of wind. You're gathering a fixed amount of chakra and then you're steadily releasing that chakra in the form of wind. You'll need to make sure it's fast and wide as the speed will give more momentum and force behind the technique.
2) For Blunt blasts: Think of projectiles. You'll gather a fixed amount of chakra like you would for any technique and then you would use shape manipulation to compact the wind into a compressed form like a ball, or whatever the technique entails. You'll then release the technique towards your opponent. The wind will be fast so it'll make impact quickly and once it does, it'll make a blunt impact almost like a solid.
Any questions so far?
