Fireworks picture shell2

fireworkspictureshell2.jpg

Fireworks photo of a star shell being assembled. The photo shows the time fuse being "cross-matched". This ensures the time fuse takes fire from the lift charge and prevents "blind shells". Blind shells are shells which fire into the air but fail to explode. They represent a danger because the shells might fall into the wrong hands and cause an injury when someone trys to ignite them.
