The first twenty seconds of this video are what I’m interested in:
Something similar happened to me a couple of decades ago: we were high up in the Rockies, with weather similar to what is seen in the video, and our hair was standing on end and crackling. We were kind of on a local high point, and I had previously heard that hair standing on end was a sign that a lightning strike was imminent, so I was freaking out as we hustled down to lower altitude.
OTOH, the people in this video just seem amused. Was I overreacting 20 years ago, or are the people in the video blissfully unaware of the peril they are in?
Maybe they just were ignorant. This isn’t basic knowledge everyone is born with. I’m not sure when I learned about hair standing on end, but I very well may have been older than those kids. (Probably not, but, still, this doesn’t have to be a case of willful stupidity.)
Now that I look around YouTube, there are a lot of these. They all feature people in exposed high places surrounded by threatening cloud cover, expressing amazement and amusement at their suddenly erect hair.
In this one her hair suddenly falls at 0:08, purportedly because lightning may have struck somewhere else and depleted the charge in the area:
In this one, one of the people seems to realize the hazard at first, but then there’s no further mention of it:
This happened to me with a group of friends I went bouldering with. We noticed it and mentioned it to each other. We knew what it meant, and about 15 miles to the west of us we saw a high thundercloud approaching. We got off the mountain fast.
