How to wire servo motors?

I'm building a wrist-mounted flamethrower, much like the Pyro system (Google it). I've got my design, unfortunately, I have NO experience with servos and electronic motors. Here's my dilemma - I have a can of starter fluid on my belt, and I need a motor to press the cap/button/switch down from a switch/button on my hand. How would I go about doing this?

Is it too late to enter for this year's Darwin Awards? Servos usually have a red wire, a black wire, and a white or yellow wire. Red goes to 4.8 volts-ish. Black goes to ground. The other wire needs a pulsed signal to set the servo position. To do this you'll need some circuitry, not just a switch. What you need is a solenoid operated valve which will open with just a voltage applied to it.
No, I misread the question. I thought you wanted to control the flow directly. You just need a standard solenoid acting through a lever to push the can button.
I've never used one, but if you take the cover off, maybe you can figure out what the different wires are for.
