This photo shows our attempt to replicate the Original Recipe. I'm concerned that the water isn't filling the 'cells' of the hardware cloth, but is instead dribbling out in droplets (and causing a modestly wider radius of splashing than we wanted).
We poked at this for a long time today trying to smooth out the appearance of our water cascading down, but had only modest luck. We did this in a flat concrete garage, so our table was fairly close to level.
Things that we've tried included:
- we folded the leftover mesh down on top of the table and taped it down. This lets the water collect in the grid a bit before going over the edge. Helped somewhat.
- higher volume of water. This helps a little, but I suspect is just masking an underlying problem.
- various folds and angles on the hardware cloth. Straight vertical seems ideal, but was insufficient on its own.
- added a 'lip' of duct tape around the edge of the table to dam up a bit of water. Does help even distribution, but otherwise little effect on filling the cells.
- played with having a container placed over the spout to smooth out the water flow. Little effect.
The biggest influence seemed to be tinkering with the table-to-disc edge connection.
- Our table is about 1' shorter
- The table edge looks a little less 'square cornered' due to the molding of the table edge.
- We're using a 600GPH pump.
- The hose from pump to surface of table is 3/4". The table opening itself is 1.5" (there's an adapter just beneath the table to convert diamaters). The height of our 'fountain head' is actually a little higher than shown in the Original Recipe photo though. Unclear whether we're effectively pushing more, less, or about the same amount of water.
- The water in our prototype isn't yet full of soapy materials, so has higher surface tension...maybe things would smooth out if we'd thought to put some bleach or shampoo in our sample?
- The hardware cloth we're using is black plastic rather than metal. The size of the cells appears to be about the same, but the grid itself may be a little thicker?
- Are others getting the 'filled cell' look with their implementations?
- Anyone have insight onto how important getting this look from our water is to overall efficiency?
- Based on the list of differences, is there something else we should try?
Any tips appreciated!
