The grenade itself consists of a canister filled with Blue Fire Powder with a second, separate chamber filled with water. After pulling the pin, the water will flood the powder chamber after ten seconds, causing a large explosion, making this tool useful for when a Hunter-nin is severely outnumbered or needs to cause a large amount of damage."@en . .

Due to the dangerous nature of Blue Fire Powder the grenades have to be stored in a dry area devoid of moisture or inside scrolls so that they are not set off accidentally by moisture that may leak in. In addition to this, the grenades themselves have to be handled with extreme caution so that an explosion is not unintentionally set off."@en .
