This technique works by first applying water infused gel to the surface that the user wants blocked off. Next, the user applies lightning infused gel to a kunai and sticks it in the water gel, causing a strong, electric current to run through it. Lastly, a final layer of water gel is applied over the electrified kunai to prevent it from being removed easily. This barrier will last until the electric gel evaporates. This technique works best in a place where it can not be walked around, such as a corridor.
