PK wheel video

Rubbing the glass sets up vibrations.
Rubbing the glass the wrong way does too.
It causes a little dance.
No laws violated.

Sound waves?

Why are we assuming that this can't be done through physical means? Think we have a ways to go before this is MDC worthy...

That's it. Even the woman in the video (Sally?), wants a physical explanation, and I don't think she intentionally rigged the video.
 
I would expect the jar to undergo slight variation in tilt with the change in how she leans her hand on the surface (and she changes hand position whenever the direction changes), which will also change the direction and speed of the spin. And the hand motions could easily be changing (this could be inadvertent) in response to the direction and speed of spin, rather than the other way around.

I doubt it is even that mysterious.

Geez, I may have to set this one up at home to play out my hunch.
In the video, as I recall, a finger did touch the glass, no?

I'll watch it again to be sure.

I don't think there is such a thing as "unambiguously clear video".

There is however, a million dollar challenge, and world-wide fame for anybody who could prove this talent.

The fact that this prize hasn't been collected says far more than any video could ever hope to.

Unambiguesly clear does not mean proof. Please familiarize yourself with the audience (Skeptiko) the person surrounds itself with and read the rest of the sentence after "clear video".

She says that she can do this on a solid table surface, too.

I'm intrigued by the idea of ideomotor effect, at least as a partial explanation. I've suggested that she try this blindfolded.

There is a simple hillbilly toy that I grew up with. I don't recall its name, but it consisted of a stick, roughly 1/2 inch diameter; 12" long, with a pin at its end that pierces a small stick; perhaps 2" long at most. The small stick, at 90 degrees from the large one, can spin freely on its pin.

The side of the larger stick has ridges carved into it, giving it a rough surface.

The user of the toy drags another stick up and down across those ridges, and it sets the little stick to spinning.
By dragging ones finger slightly while rubbing the sticks, the stick on the pin changes its rotational direction. Quite abruptly.

Vibrations.




(P.S., does anyone know of this toy I describe?)

I've always heard it called an abracadabra stick, because the rotation of the "propeller" changes when you say abracadabra. Although Walla Walla Washington has been known to work, too.

No it certainly does not.

Twenty or thirty years ago, video may have been more convincing.

But with today's technologies, one should not trust anything simply because they saw it in video.

I think some of the stops and direction changes are too fast for convection.

I have a glass tube with a blue colored fluid in it and will bulbs on each end a a few fancy twirls in the middle. When you hold one end the fluid flows against gravity to the opposite end almost instantly and if you flip it over and hold the new lower end the fluid reverses almost instantly. I was looking at it after this thread and reminded myself just how fast the heat convection works, through the thin glass wall in this case.

I don't think speed rules out heat convection, though I'm not saying that is definitively how it works. If I had one in front of me I could however, I'm positive the mechanism would be obvious and I still put heat on the top of the list.
 
Here's a question ...

Why does the operator have to be near the device at all?

If PK only works at extremely short distances, with virtually frictionless objects, then ... even if it were true ... it would be pretty much worthless.

I manifestly disagree. If there is a fifth fundamental force of nature that can be generated by the mind, then it would open up new vistas in physics and physiology. If such a force existed there might be exercises, drugs, or selective breeding that could amplify the effect.

Disclaimer: I have yet to see a scintilla of evidence indicating such a force exists.

Yet after all this time ... all the exercises ... all the drugs that people have taken in an effort to amplify the effect, where are we?

I think you might as well be waiting for the future generation of X-Men to be born.

Which I believe should be happening any day now.

The person in the video is probably one of them. ;)
 
Someone on another forum tried to replicate this PK wheel. He had no trouble making it move when it wasn't covered, but with a large drinking glass over the top he got no movement. He even tried placing a hot cup of coffee next to it.

But in the video the jar was plastic. Does this make difference one way or the other?

Midi-cholirans I was thinking of.
Perhaps Jedis, hmmmm?
But also works well the X-men thing does.

I had to look it up.

Forgotten my Star Wars lore, have I?

[/channeling Yoda]

Yes ... thankfully, I have. ;)



Anyway ... cover the jar holding the pinwheel in black, so the operator can't see anything inside.

Videotape from above.

See if that changes anything.

This.

Much like people who think they can control fish by putting their finger against the glass of the tank. Mostly their finger just follows where the fish is going.
