Did you mean kV? I don't know if 40kHz is high enough, but I know at some point it doesn't even shock anymore, just burns. Hence you can take a screwdriver in your hand, and get it close to high frequency Tesla coil / slayer exciter circuit (not that I know the difference) and have it flow through you no problem, just if you touch the spark directly it burns.

Thinner than the lag bolts are long...?

I got drill bits that can go pretty deep. The reason this shit doesn't happen to professionals like myself is that I am scared of electricity and power tools and have no clue what I'm doing and have people do it for me.

SMH

Seriously though, this is def something you take up with the landlord, the fines and payment for the repairs alone will be punishment enough.

This would be an extremely time consuming and potentially destructive process.

First, take a grinder and chop off the tips. Then go to the hardware store and get a 1/8, or maybe 3/16, bit that you think is long enough (note- these are expensive). Then go home. Tap a pilot divot in the flattened tip of the lag bolt to get started. Drill your bit all the way through the bolt without snapping it. Take frequent breaks to cool the bit and avoid dulling the edge. Note that bolts tend to be made of quite hard steel to deal with the high forces they are put under, so expect this to take an annoyingly long time. Then do it again with a slightly larger drill bit. Then again. And then again. Etc. Until your bit is just barely smaller than the bolt. Finally, you go in with a drill bit as large as the bolt, and absolutely destroy all your hard work, tearing down the sides of the bolt in a haphazard way. With a large amount of finagling and cursing, you manage to set the bit in thr hole in the top of yhe stripper pole, and finally completely destroy the bolt, so the remains fall on the floor below.

Far more expedient would be using the grinder to grind the tip off, then cut a slot in the flat surface you made. Or maybe a +. Then put either a flat or phillips bit in your impact driver, and reverse the bolt out. How well this works depends on how hard they cranked down the bolts. If this fails, I would get a hole saw, cut around the bolts, and clamp some vice grips to them to turn them out from above.

But really, I would call a real estate lawyer and force my neighbor to pay a contractor to do all the work for me.

I mean, a car battery isn't going to do anything even if you could complete a circuit. You can just grab the terminals on a car battery, 12V isn't high enough to be noticeable on dry skin.

You'd want to solder on the hot lead of an extension cord hooked up to 120 if you wanted to make sure they never touch that pole again.

Disclaimer: don't do this, it'll probably kill.

You can short the terminals on a car battery with your body with no issue (there's a theory that that's why you see it in movies so much - if anyone actually tries it the studio isn't giving them an idea that actually works. Same with duct-tape gags and chloroform), but it might melt the hardware and set the floor on fire which would be fun! What they should really do is connect a HV source and charge up the pole. Won't cause any lasting harm, but hopefully it'll convince them they drove a screw through a live wire.

For someone to get electrocuted, the current needs to flow through their body. Electricity always follows the path of least resistance, so there's basically no way to do that from upstairs.

If you attach both terminals of the battery (or a stripped extension wire) that wouldn't do it. Assuming the pole is conductive, the electricity would just go into the screws, into the pole, across to the other screw and out. If the pole isn't conductive it would probably do nothing at all. Maybe the floor is conductive, in which case it would go into the screw, through the floor/ceiling and out the other screw. There's just no way to do it where the electricity flows from a screw, down the pole, into the body of the pole dancer, then somehow back out and up to the battery.

Even if the person who owned the stripper pole wanted to electrocute themselves it would be difficult. Assuming the pole is conductive, if you attached one electrode near the ceiling and one near the floor, the electricity would just flow through the pole. It wouldn't make a detour to go through the body of the pole dancer. You'd basically have to clip one side of the battery to your toe, the other side to the stripper pole, and then grab the pole with your hands. And, even then, it might not do it -- you'd have to have sweaty hands and toes to make the path through your body conductive.

I really hate the movie trope where people can get electrocuted by stepping into a puddle that has something electricity-related in it. It's almost as bad as the trope that you get blasted backwards if you're hit by a bullet / shotgun blast.

Or glue. Glue would be hilarious.

That only solves your problem. It doesn't add problems for the perpetrator, which is the only thing we are concerned with here.
