    He is already standing too close and that stick would arc with that many volts flowing through it. The most likely outcome in reality if it had been energized. The arc would have jumped from the stick to him and no more New Zealand guy.

    As someone who has worked with academics, the more specialised the person, the less common sense they seem to hold onto.

    As such, if this was outside their PhD specialisation, then it’d absolutely make sense that this wouldn’t occur to them.

    At 10kV, a random stick would be all it takes to start an arc. He knows what he’s doing.

    I don’t remember the scene, but personally I’d test an electric fence with a nonconductor. You’ll probably get some sparks but won’t die. You do you, ppl in this thread.

      The first film paints a different picture.

      The whole point of his story in that film was his growth and development, started saying “kids smell” and ended holding two of them safe.

      He was the one throughout who kept his head, stayed competent in the face of fear and dealing with chaos.

        Characters in Jurassic Park are portrayed as flawed, imperfect people who make mistakes. None of the plot relies on them being idiots or anything, but people screw up, panic on occasion, and don’t know things from time to time.

        Dr. Grant using a stick to test the fence is a mistake, albeit a small one without real consequences. While it doesn’t distract from his character arc of how he feels about kids, it is his character simply messing up.

        I also disagree with the person you replied to. While their assessment is correct, Dr. Grant is a character with a lot of time working in the field and therefore has a lot of practical skills. He does way, way better than a doctorate in mathematics working in academia would. Writing off all people with a doctorate (or experts in general) as being hyper specialized is a mistake.

          The difference between a regular idiot doing a dangerous job and an engineer doing a dangerous job is the engineer knows which parts of the job he’s risking imminent death on. There may often be no other difference.

      Really?

      Genuinely asking, I’m just an engineer… with very very bad grades. Passed was enough for me.

      Once a professor asked me if I wanted to take the exam again because it was clear that I knew more than what I showed on the exam (a lot of 2 + 2 = 5 mistakes, I was fairly good at that and owe most of my low grades to that). I asked him if I passed, he said yes. Fuck that shit, I’m taking that grade and parading it across town, wooohoo 🥳.

      Air only has so much resistance itself. High enough voltage and the closest path to ground is where the charge will go.

      Just like with Lightning

        Humidity in the air makes that wayyy more dangerous because your skin will be highly conductive and the lower the resistance, the higher the current (which is what really hurts).

        I’ve been a human grounding strap a couple times and don’t recommend it. I think the vibrating pain of AC (someone reenergized the outlet on me) is worse than the punch of high voltage (failing spark plug wire I grabbed with metal pliers while diagnosing a misfire).

      My arm once got pulled into an electric fence when I was a kid and I couldn’t stop getting shocked until someone physically pulled me away. It was more of a self-control issue than accidentally bridging the gap.

      That was the day I learned that some pain can be pleasant. The owner of the property didn’t seem as pleased with my discovery as I did. He had to shut off the fence and yanked my arm away and then told me to go explore my perversions somewhere else. I was too young to understand the word “perversion,” and I’m now eternally grateful to that poor unprepared rancher.

        You find it enjoyable? I regularly touch electric fences, but not because I want to but because I’m too stupid to think of another way to figure out if the thing is working. I find it to be the opposite of pleasant.

          Oh. Here’s your fix:

          A longish piece of green grass. Hold it by one end, then slide it on the fence wire like the grass was a violin bow, getting your fingers closer and closer to the fence. At some point you notice a pinging, or your fingers are touching the fence.

          You can use this to gauge, very roughly, how powerful the charge is at that point.

          I never said it was pleasant. But sometimes some types of pain are the right kind of pain.

          Example of the opposite: when I’m swapping a switch in my old-ass house, sometimes I’m too lazy to turn off the breaker. When I inevitably shock myself, I say “dammit” because I’m trying to concentrate, not discover my preteen proclivities.

          Edit: well slap me silly and call me a liar, I literally said the words “some pain can be pleasant.” I blame this error on undeserved confidence and complacency.

      At approx 3kV/mm, you would have to be pretty close to a 10kV fence.

      Humidity plays a big role as does the frequency that the fence is running on. But you would be pretty safe standing a meter away, on that dry sunny day in the picture.

      Also above a point, the high voltage causes the conductors to buzz.

      I have a 10KV electric fence. 5KV to 15KV is typical electric fence voltage in a farm or bear prevention fence. Can’t feel a thing unless you actually touch it.

      They are also not lethal. Very low current, just very high voltage. So it only hurts like fuck, but won’t kill a human, cow, or any other mammal that touches it.

        They can kill an animal (including a mammal) if they become entangled and give up out of suffering, though.

        This is pretty rare, but can happen.

        It’s virtually zero risk to a human, though, who can cognize things like getting their hand disentangled from a string (even in a panic situation), or to most mammals, which tend to jerk backwards on contact.

        They can’t kill you, but I know from experience that they can knock you out for a bit if you get shocked through your head.

      This is why you should never try to remove a tree from a power line yourself.

      Electricity always takes the path of least resistance back to the source. A tree, and possibly your body, may end up being the “path of least resistance”.

      You won’t know if YOU are the path of least resistance or it the line is even energized until it’s too late.
