Railgun

So the railgun is a launcher that is based on the Lorentz Force. It utilizes two parallel rails that are bridged by a bar of metal (iron...?) that is called an armature. In front of it sits the projectile. A positive (+) current is connected to one rail, (I think the right one) and a negative (-) is connected to the other. When the power source is switched to "On", the current forces the armature forward, consequently forcing the projectile forward at high speeds.

I was going to build one of these, but my mom wouldn't let me use a few car batteries. Something about electrifying myself. Bullshit. Anyway, the railgun requires an enormous amount of power, therefore I would need...say, 4 car batteries. Oh yeah, if you have any electronics around (such as phones, computers, cameras...) they'll get kinda f****d up when the gun fires, because there is an enormous ammount of tesla (lightning) output, and the EMP (electromagnetic pulse!!!) will fry the shit out of the wires.

This is going to be a project for this summer. List of items I will need:

2 bars solid titanium (3/4", 4' long)
1 flat surface (probably a 3" thick piece of plywood)
2 packs of hose clamps (1/4", extra-strong)
5 shitloads of high-voltage wire
1 10-pack of high voltage capacitors
4 maximum charge car batteries (preferably lithium)
2 toggle switches (in case one breaks)
1 Solder Pen
1 can Teflon solution
And a lot of good luck.

Now it's just a matter of working up enough money to buy all this.
