It was brought to my attention that the Crystal glue cell could be making magnesium chloride. Magnesium chloride absorbs water from the air like crazy. So if its making magnesium chloride that its nothing more than a water battery. So I ran some test that can not confirm that its pulling water from the air and thus is the reason why it works. I’ve made a table salt and Epsom salt glue cell and it has the same opportunities to make magnesium chloride but it does not and it dies off. Also physical appearance of the crystal glue cell to the magnesium chloride cell shows that the crystal glue cell rock hard while the magnesium chloride cell is wet and gooey. If the crystal glue cell was pulling water from the air than the glue would never dry and it would remain wet looking like the magnesium chloride and glue cell. It can not be confirmed that the crystal glue cell is a water battery.
