At the five minute mark, the water is starting to look like a vat of low grade whiskey mixed with hobo urine. No discernable difference between the test and control group.
At the ten minute mark strange bubbles start to form on the surface. While both groups show bubbles, the experimental group seems to have a greater proportion.
At the end of the 30 minute run, both groups show similar water color with a mix of sediment that looks like paprika and algea floating on the top of the water.
The experimental group shows more bubbles, but that may be a function of water level. The control group does not have feet to displace water, thus has a lower water level. The bubbles seem to emerge from the point where the ionic plate hits the water down to its end under water. The more of the plate under water, the more bubbles you get.
So who knows for sure what effect this device is having. I am tempted to run a few more trials, including additional test groups such as a pack of hot dogs and maybe a small child.
