Yes I remember my old electronic kits when I was young (of course I'm 19 and still considered young ;) ). But anyways, one expirement told me to put the two wires in water, but they said to put some salt in there before, and that would cause it to conduct electricity better, and of course, they were right

That will also create ferric oxide (aka rust), which can be used to make Thermite!

Salt makes a big difference because it is an electrolyte. It passes charge very well.

What's Thermite?

Thermite is a compound that burns *extremely* hot. It requires magnesium (or other very hot thing) to even ignite, but will then burn through an entire engine block (supposedly). It can be made from "common" household items. If you're interested in further information, PM me.
