These are Futonn Jutsu that I and any other can do. (Made up since only one has been shown)
Boil Release: Acid Rain Technique
Ninjutsu
This jutsu creates a acidic mist that forms a small cloud. The user can then move the cloud above their target and disperse it, covering the target in acid.
Boil Release: Boil Clone
Ninjutsu
The Boil Clone Technique is similar to the Shadow Clone Technique except it creates clones out of Acid. Like other solid clone techniques, the clones can be used to perform tasks the user is unable or unwilling to do for themselves. The range of the clone is limited however, as it can not travel very far from the original body. Additionally, Boil clones only have one-tenth of the original person's power (canon weakness for clones). Like other clone techniques, if the Boil clones are injured enough they will revert back to normal acid.
Rank C-rank
Class Supplementary
Hand seals Tiger
Boil Release: Gun Shot
Ninjutsu
The user kneads chakra, and converts it into Acid, and then spits it out in the form of condensated balls. The high-speed acidball attack possesses just as much power to kill as an actual gunshot. While this is a boil release technique, it can still be employed someplace where no acid iis available, which is a great advantage. It's also possible to increase the power of destruction of the balls themselves by building up the chakra inside of them. The number of bullets is determined while kneading chakra. By taking advantage of gravity, the bullets can brutally increase in power.

Boil Release Acid Shockwave

This technique allows the user to make a spiraling vortex of water from the moisture in the air. The vortex then proceeds to explode from the top in the form of a wave. The user can control the direction the wave goes.

These are all jutsu based on real water jutsu. I tried to leave out jutsu that that would be to difficult to face like bursting collision wave kisame's flooding technique
