On July 30, 2007, Directory:Scott F. Hall posted a video at YouTube showing a continuously running gizmo composed of a conglomeration of things found in his kitchen, including a can of dog food, 4 toothpicks, refrigerator magnets, a pencil, spring clips, and a small corner cut out of a box.

: "Basically, I have no idea what is going on with my dogfood can device. I was simply fooling around with some magnets and things in the kitchen and concocted it. It turned on me and kept turning!" -- Scott Hall, Aug. 8, 2007

Set-up : Three toothpicks are fastened to the box corner by scotch tape, and that nominally-balanced tripod is set up-side-down on the fourth toothpick, which is held vertically by one of the clamps. Three refrigerator magnets are placed at the base of the toothpick on the three sides not occupied by the clamp. On top of the left and right arms of the clamp are placed two smaller magnets, each side. The orientation of the magnets is not mentioned. Next to that set-up is placed a can of dog food, with a pencil held in place by another clamp held in such a way that the pencil's point is suspended over the top of the inverted tripod of toothpicks.

It Spins : The astonishing thing about this is that the tripod of toothpicks appears to spin continuously.

Replications : Replication attempts thus far have been unfruitful (as of Aug. 8, 2007, 11:20 am mountain time). (There was an error working with the wiki: Code[1])

Skeptics : Skeptics say that the toothpicks are spinning via an unseen source of blowing air, or an AA battery with black tape covering it.

Objective : The purpose of this PESWiki page is to report on this phenomenon and to encourage the open development of a clear set of instructions so that it may be replicated, documented, characterized, then implemented into a practical application. This is a publicly editable site. Feel free to participate.

Electro-Gravitic Perpetual Motion Machine from Kitchen Items - Title chosen by Scott F. Hall, who posted this video of his on July 31, 2007. (YouTube)

Comments by Scott Hall

"No aluminum foil--just clear plastic tape and cardboard in the pyramid. I assume the graphite is a conductor of electric current. Magnets--yes. I really don't know what's going on with this either. I just built it from a thought off the top of my head. It turned. Weird, I agree." (Aug. 9, 2007)

How it Works

Parts List

As described by Scott.

Seven round refrigerator magnets

a tiny cardboard pyramid with three sides (i.e. cut off the corner of a tiny box)

four flat toothpicks

three tiny bits of scotch tape for attaching three of the toothpicks to the pyramid

a graphite pencil

two rubber insulated spring clips to be used as clamps as shown

an unopened can of dog food (chunky beef flavor, which may or may not matter--I have not yet repeated this experiment using a different flavor)


As described by Scott.

Assemble the items into the configuration you see here. As the final step, bring the point of the pencil very close to the top of the pyramid without actually touching it. Rotary perpetual motion commences. If it does not, then lift off the pencil, wait several more minutes, and try again.

Theoretical Postulation

As described by Scott.

I think what's happening here is an electro-gravitic effect in which the array of magnets act in conjunction with the rest of the structure to rapidly gather minute quantities of static electricity from the surrounding atmosphere. The can of dog food acts as a capacitor rapidly storing the charge. When the graphite pencil nears the pyramid, energy apparently trickles across the gap and counterclockwise rotary motion results. I wonder if the rotary motion would be clockwise instead if I built this machine in the southern hemisphere?

Very possible that Scott F. Hall motor effect is similar to homopolar motors made from simple battery with small magnets. Possible that dog food in metal can is acting as battery.


none likely


Replication attempts thus far have been unfruitful (as of Aug. 4, 2007, 8:20 am mountain time). If you have replicated this, or know of someone who has, please click on the "edit" button for this section and post that info.

post here

(Just click on the "There was an error working with the wiki: Code[1].)

If you have a lot of information, feel free to create a separate page to set forth a description of your replication, modifications, and results.

Data Recommendations

In addition to describing the experimental set-up, such as materials composition, the data you will want to tabulate include:

speed of rotation

duration of rotation

direction of rotation

atmospheric conditions





Also might try using such measurement apparatus as:

Kirlian photography

Magnetism visualization tools


Forum - Yahoo!Group started on Aug. 1, 2007 to facilitate in the replicating, characterization, improvement, and development of this concept into something practical.

Questions for Scott

Do you have any reservations about us posting this as an open source project?

Does the rotation begin without giving a push to the toothpick tripod?

In what N/S orientation are the magnets placed?

What are the make/model of the refrigerator magnets? dimensions?

Do the insulated clips have to be metallic and magnetic?

Are the magnets placed with all the poles facing same direction?

Variations to Try

After faithful replications have been accomplished in sufficient number, in addition to removing the different components to see whether they are crucial, the following variations might be attempted to characterize and optimize the design:


Different number of toothpicks in rotation apparatus

Variation in toothpick size and shape

Variation from toothpick (other material, e.g. dowel, plastic)


Variation in post composition (rather than toothpick)

Post different from rotation apparatus material


Different configuration of magnets

Different shape, strength & size of magnets


Vary distance from top of inverted rotation apparatus

Various led types for pencil

Other than Pencil


Try different sizes, compositions

Various distances, heights, and locations with respect to apparatus


Try different compositions, lengths, fixed material substitutes Forum
