Good explanation Steve!
The set up in the video is indeed overly complicated. You could just take a bottle and poke a hole on the side, close to the bottom, at the same height you want the water level to be at. When you fill the bottle with water, plug up the hole with your finger. Make sure you close the bottle cap before removing your finger and placing it on the tray.
One issue I ran into is that if the hole is too small, air won't be able to enter the bottle with sufficient ease, so water will stop flowing. Make sure you test it out at least once and if this happens, just make the hole a bit bigger.
