    Crackling fuse is most commonly used for various coloured effects fireworks even though it can be used in place for regular visco. It is a cord with a pyrotechnic composition core that burns with a fierce crackle in gold, green, red, silver or purple. There are three layers that make up the fuse. The first one layer of string is wound around the core, then a second, less tight layer of string is wound in the opposite direction to prevent unravelling. The last layer is a low-nitrate NC Lacquer to waterproof the strand and to prevent it from falling apart. The fuse burns at 24 seconds per foot. It is typically cut into small sections and placed inside a shell that is fired from a mortar tube or payload for a rocket. At effect time the small sections of fuse ignite and quickly propel themselves in the air in erratic directions while crackling fiercely.

    Has more of a novelty application for our use, almost a firework in itself! Burns with MASSIVE power, MUCH faster than regular visco.

    Its the compreesion that triggers the very sensitive crackling particles inside, the safest way to cut this fuse is somewhere it is unlikely to cause any problems should the worse happen and it ignite, in the dark it will spark 9 times out of 10 but never had an ignition, always best to be safe than sorry though.

    so a sharp blade and slight pressure would be best?

    And somewher away from anything that could be affected should the fuse ignite.
