Homemade Thermoelectric Cloud Chamber

This cloud chamber is cooled by two peltier heat pumps stacked on a  computer fan cooler. The sponge is fixated by a screw which is connected to voltage multiplier (Cockcroft-Walton) to generate an electric field in the box. It works specially well in cold rooms.
Here is a sample of the cloud chamber functioning with a slightly radioactive thoriated electrode in it.
