What's a good way to bend styrene tubes and cylinders?

I am playing with scratch building models. What's a good way to bend styrene tubes and rods?

Is there a tool for it like a pipe bender for styrene?
 
A candle.
If you very carefully heat the tube near a candle flame, you can bend it easily. Practice a few times till you get a feel for the distance/time that you hold it near the flame. If you bend it slowly, you can avoid kinking it.
 
Micro Mark sells a set of metal spring tubes that are for bending hollow plastic pipe. Slide the pipe in the spring and heat it - then bend. When it cools, slide the spring off. You can get fairly sharp bends with no kinking.
 
Another trick is to fill plastic tubes with sand and then heat them up with a hair dryer or a heat gun. The sand will enable the tubes to keep their original diameter when they're bent so they won't deform.
 
Thanks for all the good advice everyone. I really appreciate it.

I'v been dabbling in scratch building and kitbashing and I really like it. I am exploring other techniques and materials, so this really helps.
 
Depending on the diameter of the tube/rod for your model, another option is just using plastic-coated wire, or even just plain wire. I've used that green floral wire for a couple of projects. For small diameters, this can be a lot easier than using plain styrene.
It's available pretty readily, and doesn't require any special techniques or anything to bend. Once it's on the model and painted, you can't tell the difference anyway.

Example below. On my scratchbuilt Falcon, all those little "conduits" with any kind of bend in them started out as green floral wire. I bent them by eye with a couple pairs of small tweezers, and used superglue to attach them.

Yep I used plastic coated wire a few times - A TON easier then trying to bend styrene to shape... 2-3 miutes of careful bending and you're done... and if you screw up the entire spool only cost $2-3.. you can't beat it really...for bent piping anyway ;)

Yeah, when you use plastic coated wire or even bare wire it looks like little conduit pipes running everywhere. Gives a real good effect!!
