Can a laptop charger be modified to charge capacitors?

Well. I've been wanting to build a coilgun for some time now, so I decided to look into it. Capacitors are safely (or as safe as you can get) charged with DC current (batteries). But I don't want to go out and buy batteries whenever I want to use the coilgun. So... can I somehow wire it to charge a "capacitor bank". I was thinking start somewhere with cutting off the computer-plug?
