What can you do with 120KVolts?


Have fun!
SO, we found this 120KVolt discharge unit on reuse - an amazing find. We immediately to it back to our dorm to test it out. When we turned it on to see if the lights on the control panel lit up, it started arcing to the ground - into the cement! Here is a video. As we pumped up the voltage, the blue haze from the electrode turned to a coherent arc to the ground, as seen here. When we pumped it even higher it started sparking from the electrode around to the collar of the plug (electrical ground).
Next, we decided to try to setup a Jacob's Ladder like setup where an arc of electricity would jump a gap then rise due to heat. Unfortunately, although the voltage was high enough to bridge the gap, there wasn't enough current to sustain an arc across. Here is a video. As you can see by the video, the two lengths of wire were drawn together when current was flowing through them because of the opposing magnetic fields created - or, at least that's my explanation.
Next, we wanted to see how large of a spark we could make, so we brought the two wires apart, and faced the two ends toward each other. We ended up having an unexpected problem, as the electrode wire was arcing to ground Around the 2x4!
We ended up using a plastic sheet to add a little more insulation between the electrode and the collar and it started to bridge the gap. You can see a video here. Once again, the current wasn't high enough to sustain a high enough voltage to keep a constant arc (if that makes sense - it's a weird circuit design, as we learned later).
As we brought the ends of the wires further apart, the last thing we observed was a weird hazy blue stream between the bases of the wires. It made a weird sounding shushing noise and smelled heavily of ozone. As we insulated the bases more, and brought the wires even further apart, the unit started to buzz softly, the POP, CRACK, and that was the end of the 120KVolt power supply.
This was an especially dangerous project, and we used all precautions and always stayed a great distance. You can never be too safe though, and should never attempt to use any dangerous items that you are not very familiar with. Do not try this at home! It can easily be lethal!
