This technique was developed from a forbidden technique that Deidara stole from Iwagakure. By using the technique's ability to knead chakra into objects through the mouths in the palms of his hands, Deidara can infuse clay with explosive chakra. He then moulds it into a shape depending on the abilities he wants it to have and spits it out. After moulding the clay, Deidara can enlarge it to various sizes depending on the intended purpose of the clay. Once enlarged, the clay creations can be brought to life and controlled remotely by Deidara, who can then detonate the clay by saying "katsu" (喝) and performing the seal of confrontation. Though the explosives are powerful, they are all earth-based techniques, and as such, can be defused by a lightning technique.
