Water Prison Technique

This technique is used to trap a victim inside a virtually inescapable sphere of water. The only downside to this technique is that the user must keep at least one arm inside the sphere at all times in order for the victim to remain imprisoned. This technique requires a sufficient amount of water, which can be provided by expelling it from one's mouth. Despite the fact that the prison is made up entirely out of water, it is stronger than steel as stated by Zabuza Momochi. Once trapped the target is unable to move while within it due to the heaviness of the water. Because of the density of the water it can be used, to a limited extent, for defensive purposes if performed on oneself.

Water clones can be used in preparation for the technique, which block an opponent's attack and trap the attacker in the prison using the clone's own water. Neji Hyūga was able to use his ability to release chakra from all of his tenketsu simultaneously to disrupt the flow of chakra and break the prison. It can also be stored in scrolls as traps.

Trivia
Whene Zabuza Momochi used this technique at Kakashi he was still able to breath, Move and talk inside the prison but whene Kisame used this technique at team guy they were drowning inside the prison and they couldn't breath, Wich probaply means that the user can control the aspect of the prison.
