The two Frey Scientific-584283 platinum electrodes were constructed with a 2mm by 2mm platinum foil welded to a led wire. The led wire was encapsulated in a 10cm glass tube with the platinum foil protruding out of one end. The other end had a 10cm copper wire exposed. The two electrodes were placed side by side and the heat shrink wrap was placed around both electrodes. The wrap was placed to cover 3m of the glass and 6cm of copper wire. The heat from a heat gun was applied to the shrink wrap, joining together the two electrodes. (See fig. 4) This wrap was placed in order to protect the copper wire from splashing that occurred as a result of the bubbles escaping the solution. This electrode served as the anode.
