If and when you try this, have on hand a nice thick wet rag. After you apply the heat and solder, grab the pipe (with a rag it will be hot) and use the wet rag to clean up the solder, you just grab it and twist. This will prevent any drips and give a clean finish to the solder. You don't need to use a ton of solder because it wont have to hold water under pressure.
Here is a YouTube link, he does it a little differently, but essentially it is the same.
Of course you could just glue or crimp the joints if you would rather.
