Inverted Bubble Fountain

This is a fountain head I designed that creates an amazing inverted bubble shape. It is designed to slip over a standard 1/2" PVC Pipe Coupling. The threaded head can be rotated to adjust the size of the bubble. In order to lock the head to prevent it from rotating on it's own, cut a very thin rubber band and insert it into the female threads in the base before threading the head into it.


Here is a video of it installed and operating in my swimming pool.
