A couple of months ago I stumbled upon a clip from either TickleAbuse or TickleIntensive. Besides tickling it featured a picrelated item which has a very unassuming name - High Frequency Device. When operated normally it creates a bunch of small violet sparks which don't penetrate deep under the skin and are hardly felt. I got one for myself and those sparks are barely doing anything on the arch and are completely useless against the ball of the foot. The reason I got it is because as far as I remember in the clip itself this kind of device was creating powerful white discharge which was well felt on the feet. That clip is long gone from the YT and I didn't save it at the time so one could blame my memory being wrong but recently I got another confirmation that such spark is possible. Specifically at the end of a stupid ass WT short: https://youtube.com/shorts/6zjSFyKu62k?si=-R3Mx_mDgzZ4yBUV I tried a couple of things to recreate it: 1) Added salt water to the skin to decrease resistance. 2) Tried to hold it at max setting for some time to "accumulate the charge" and then bringing it to the skin. 3) Tried to touch the ground (heater in my case) while using it. 4) Tried to apply baby oil to the skin to increase resistance. Neither of all mentioned above has yielded any results. The thing steadily generates a bunch of weak violet sparks. I don't understand the working principle of the device very well but can give a short description. It consists of a handle with a power cord and intensity (voltage control?) dial. Into the handle an electrode is inserted in a form of a glass tube filled with noble gas. Sparks jump the gap between the endpoint of the tube and the skin. My questions to all of you is: 1) Do you know how to make it spark like at the end of that WT short without interfering with the inner workings of the device. 2) If not can you uncover the operational principles of that thing and what can be attempted to modify it for the desired result? 3) Do you have the mentioned clip so I could analyze the way the device is used and what possible modifications it has? Thanks for the attention.
