- Explosive Tutorial II - In this I am going to explain generally how an electrical detonation works. An electrical detonating system is somewhat safer than that of a non-electrical system. You don't have to worry about things such as the wrong people walking by when your explosive goes off. Instead of using a fuse you use an electrical igniter which is composed of two wires with a thin wire on the tip made to glow red hot when an electrical current of about six volts. On top of the thin wire is somewhat of a hard powder on the tip to help the ignition. It is all set off by a detonator, which is just a box which produces an electrical current with a few switches to break the current when not in use for saftey. These can set off numerous explosives at once if you string the wires out from your current source in two or three sets of wires coming out instead of just your positive and negative you have two or three of each. Just one word of advise, ALWAYS make sure your saftey switches are on before even thinking about attaching the wire from your detonator to the ingniter in your explosive. --------=>Vortex
