    Wouldn’t expect the bar itself to get hot; just the battery. The bar will be very low resistance and therefore only a tiny portion of the total heat will end up in it.

    Now, if you stuck one terminal to one piercing and another terminal to another piercing, then you might have a bad time…

      There’s not enough voltage in a 9V to drive current through that big of a resistance

      Edit: I understood them to be saying across two nipple pericings, one on each side. Thats a massive amount of electrical resistance under the vast majority of conditions, and 9v isn’t very much

        Just soldered some stuff together and tried this out. The battery was already pretty dead, but it still raised the temperature of the wire by 9°C in like 5 seconds. If the battery had been full it would have gotten much hotter much faster.

          You missed their point. They were suggesting connecting the battery to different nipple piercings, thinking that would cause the electricity to travel across the chest.

          That being said, kudos for the experiment

          The person I was replying to (to my understanding) was talking about connecting it across a two nipple pericings, one on each side

          I would be flabbergasted if 9v were even remotely capable of overcoming that kind of resistance

          Edit: just tried to see if I could even read the resistance of my chest/boobs from nipple to nipple and even putting my probes immediately next to eachother on the most sensitive setting I was incapable of reading anything at all. If you’d like to try and replicate, or can explain or why I’m wrong I may concede, but I think you just misunderstood what I was saying

        If you mean the bar, then even stainless of that size is going to be very low resistance - milliohms?

        If you mean the body, then I believe it gets complicated. Skin resistance will be diminished by the piercings having a relatively large contact area and probably being somewhat sweat covered - I’m not sure exactly what the ‘skin’ inside the piercing tunnel is like. Certainly you can feel current from a 9V across the wet inner-body skin of your tongue.

        The internal path will be quite low resistance because the inside of the body is a sack full of salty water.

        It wouldn’t be fatal, even across the chest, but it could hurt.

          If you touch the contacts of a nine volt battery to your bare skin you generally don’t feel anything; you might if there’s sweat, you’ll feel it on your tongue, but across two breasts worth of chest like I understood them to mean in the comment I was replying to?

          Thats a fuckton of resistance compared to 9v of electrical pressure

          Edit: I’m literally doing so as I type this. Even against areas of my skin that are more likely to have electrolytes and moisture like my underarms- I feel absolutely nothing. 9 volts is a pitiful amount of electrical pressure compared to the resistance of the body. Go get a 9v. Try it.
