I use this little fun device now and then, on some of my portrait shoots when I want some dramatic spotlighting. I thought I would share how it's made.
Now I didn't invent this thing, I had seen it on a website years ago and I can't find the site any longer.

Ingredients:
One camera flash
A small piece of PVC pipe
1 Flexible Pipe Connector
I added a hanger to give the PVC some support when it's on my stand and I also added some black spray paint just to make it look cool!
Here is what the bazooka looks like:

Here are a few of the results:
