Dud shell

From PyroGuide

Dud shell - shell rises but fails to burst at the proper height and falls to the ground as burning or live pieces. Dud shells have been responsible for many accidents involving children finding them after a fireworks show, thus it is important at first daylight to carefully check the whole area where shells are likely to have fallen the night before.
