Problems with soldering copper piping...any tips?

I'm trying to extend an outdoor water faucet about 4" higher. It's 3/4 copper piping. I'm having trouble trying to solder the coupling to the existing water pipe. I can't get a good seal because the solder keeps dripping downward. Is there a way to keep the solder from dripping and getting a good seal? Any help is appreciated.

Proper flux and solder creates a capillary action that sucks the solder into the fitting.

Make sure all the water is out of the pipe, along with opening the valve while soldering so that internal thermal expansion doesn't try to blow pressure out of the solder joint you are working on.
