I managed to extend a remaining coiled tungsten wire section that I thought would be too short, allowing another test. I used, as previously, about 36 ml tap water + about 1g acetone + 1ml 0.1M KOH solution
Below is a video of the last few minutes of testing with it. Current readings from the multimeter were highly unstable. The bright white flashes were associated with strong EM noise that could be heard on loudspeakers nearby. This time the wire seemed to perform well until the very last few moments when a large section vaporized, ending the test.
