I'm getting closer!
I made some adjustments today (hooray for half-days!). I packed more straws into the pipe. More could fit in there, but I've used all 1000 that came in the box. I also cut away some excess screen that was holding the straws in place.
I shortened the tube by quite a bit, so there is about 2 inches between the end of the straws and the outlet hole.
In the end cap, I duct-taped a metal washer after using some sandpaper to smooth the washer-hole as much as I could. Before putting the end-cap back on, I placed screen over the end of the pipe, so there is a layer of screen again between the straws and the output hole. I'm not sure what purpose this serves, but it's in the original patent for these puppies.
The results are much better! It's not perfect, but it's much, much better.
I'm not sure what the end goal is. I think the dream would be to embed this into the ground, and form an arch over the walkway to our front door, recirculating. That would be awesome, and not really that hard.
Sorry for the shaky video.

Woot! Nice work. That is looking sweet.
I think I have a pump lying around. You could probably put it in a tub, shooting not quite straight up, and have the pump submerged. That would already be neat.
Half days?
Half day from work.
Tell me more about your pump! I'd love to get this on some sort of recirculation system.
I think the next major step is adding an air-chamber to the system to absorb and counterbalance water pressure changes...
I'll have to check. We used to have a couple extra pumps for our fish tank (when we tented our old house, we put the fish in trashcans for a day, so they had pumps). They may not be strong enough.
