Effects of pressure, heat , and humidity on the crystal cells
This shows the effects of pressure, heat, and humidity, on one of my homemade crystaline voltaic cells. The cell is composed of Epsom salt, Rochelle salt, Alum, and a small amount of iron pyrite fillings. The mixture was melted together on the stove top with no water. The cell produces a very tiny amount of electricity but is very effective at showing a response to the above mentioned conditions.
