DIY hydor?

Hi, just jumping on board as I am interested in trying to make something myself.

i've thought of something along these lines (latest version of quicktime required to view)

Just need to figure out how to attach the sprinkler portion to the piping, and allow movement. I think you can control the speed at which it's spinning through the friction/tightness it's attached.

I think these steps should work:

1. cutting a groove along the top of the "inner" pipe
2. the outer pipe is cut in half length wise, then a groove cut in each piece so it fits into the inner pipe
3. glue the split pipe back together over top of the inner pipe
