Yeah... reading it in further detail, he applies current across his head between the mastoid processes. I thought it was local stimulation between two surface electrodes under the ear. A quick look at the literature shows that the targeted structures are too deep for an approach like that, so they have to go across the head. Style points for bravery, I guess, but I certainly wouldn't want to pump over a milliamp of d…

It's only bravery if you know the risks. :)

Going on a tangent but upon reading about vestibular reflexes I recalled something I used to do as a kid: When in bed, ready to sleep, I could condition myself to believe the bed was tipping over to the side, up to the point where I would have the reflex of grabbing the sheets to keep myself from falling, similar to jolting awake up after falling in a dream. I wonder if something could be done to manipulate these per…

I'd love to understand the brain's capacity to fool itself.

Sometime in my 30s I discovered I could "make my ears retract involuntarily". I'll think about pulling them back without actually trying to do so, and at some time in the near future that I can't anticipate, they'll retract.

It's a 9V battery. Relax.

That's the kind of thinking that leads to stuff like this:

> Jennifer Strange, a 28-year-old mother of three, was among 18 people who entered the "Hold Your Wee for a Wii" competition. They tried to drink as much water as they could without urinating in a bid to win a Nintendo Wii gaming console....

"It's just water. Relax."

> "Not with water," a male disc jockey replied. "Your body is 98 percent water. Why can't you take in as much water as you want?"

> "Maybe we should have researched this before," the female disc jockey added....

> Strange drank nearly two gallons of water in over three hours on Jan. 12, 2007. During the contest, she could be heard complaining about pain to disc jockeys at 107.9 "The End."

> "Oh, it hurts," Strange said, while one male disc jockey remarked that she looked pregnant and another, a woman, said "That is so funny."...

> Strange left after taking second place, winning a pair of concert tickets. She then called in sick at work and died in her bathroom just hours after the contest.

A 9V battery is enough to deliver a lethal current under the right conditions. Don't play with electricity unless you know what you are doing.

It's also the kind of thinking that leads to getting killed by 9V batteries. https://darwinawards.com/darwin/darwin1999-50.html

Slightly OT, but since the focus shifted to safety: is that battery really dangerous? I'm really asking.

I remember, as a kid, testing for charged 9V batteries touching the bare electrodes with my tongue. It was a funny feeling, but that was way before the "little chemist" became the dumbed down shadow of itself and everyone was screaming "safety".

For science, ladies and gentlemen, I'm now measuring the resistance of ~5mm of my tongue: it's 90kOhms, that should be a lower bound regarding the experiment.

Your example doesn't show why a 9v battery used in this way is dangerous.
