If I remove the middle wire that goes up and down, in the center, there is a change in motor speed, a very noticeable change, thus showing that there is flow in the middle wire, the electron path follows the path drawn, if it did not follow the path drawn and if the middle wire going up and down where electrons flow in both directions had no flow, there would be no change in any motor speed if it was removed. It would be the same as if it did nothing. The electrons are taking the path of least resistance, as drawn,,and that shows that electrons can flow in opposite directions along the same wire at the same time.
You are right about the motor speed. If you keep the verical wire, you got two separate circuits, and a parallell circuit between the battery cell and the motor. If you remove the vertical wire the motors are now connected in series, and a slight difference between those motors (It could be friction, efficiency, anything), you might end up with one stalled motor and one running.

I made a new video,concerning electron flow,this time I think I got it right.http://www.youtube.com/watch?v=b8eUbyWa-cY

Steven,

Have you drawn your circuit out and examined the loops?

I just did myself. If you do, you'll find when both batteries are connected as you showed, virtually no current flows in the single battery, and the power for both motors is supplied by the two batteries in series. You'll also see that current flow is in one direction.

Batteries are another example of non-electron or "ionic" conductors. When you connect a lightbulb to a battery, you form a complete circuit, and the path of the flowing charge is through the inside of the battery, as well as through the light bulb filament. Battery electrolyte is very conductive. Down inside the battery, within the wet chemicals between the plates, the amperes of flashlight current appears as a flow of both positive and negative atoms. There is a powerful flow of electric charge going through the battery, yet no individual electrons flow through the battery at all. So, while the current is between the two plates of the battery, what's its real direction? Not right to left, not left to right, but in both directions at once. About half of the charge-flow is composed of positive atoms, and the remaining portion is composed of negative atoms flowing backwards. Of course in metal wires outside the battery, the real particle flow is only from negative to positive. But inside the battery's wet electrolyte, the charge-flow goes in two opposite directions at the same time. And if we built a circuit from hoses full of salt water, with no metal conductors used, then all the current would be bi-directional.)

If the particle flow is from the neg/South magnetic pole,to the pos/North magnetic pole,then the two like poles are going to repel the particle or current flow giveing you zero.

I could debate over this but I wont,much,, what is is right. And you know or you dont. Either way you will believe what you want,,and thats ok we all do. I will mention however that I did disconnect each motors power input in the video, showing neither changed speed when that happened, and that one motor spins faster and has more torque which is the one powered by the two batteries in series where as the other motor,,the one with the purple paper propeller on it spins slower and has little torque since it is powered by only one battery. But Ill not debate it further, take it as it is,,if you can use it,,then do,,or discard it. Worst case Im wrong, its still a very handy concept to ponder I think. Best wishes steve....

Please, could you add diode to this short wire where electrons are flowing both directions in such direction to allow only one of this flow. I'm very curious about this but can't check it.Thank you.

I'm not sure this is real relevant but I had a handheld   radio transceiver that had a coax cable coming out of it to go to the antenna.  It transmits RF (high frequency AC) out the antenna.  That SAME coax (two wires as in a center wire and a shield as the second wire) was used to feed DC power in to the transceiver.  This was a mod with a diode to save having two separate cables (or 4 wires) going to the radio.  So you had DC going in on the same wire that AC was going out when it transmitted.  In that configuration it did not use any internal batteries.  It worked fine.

Reminds me of some solar panel experiments I have did in the past, and found out rf can power a solar cell, believe it or not its true. Also many solar cells use the non visible spectrum of light for energy conversion, all tho most would assume its the visible spectrum they use. For example I took my roomba ir virtual wall. It simply shines a light not in the visible spectrum,,that the roomba can see and so it avoids that area. Anyway the virtual wall ir light can actually be seen as visible light when viewed in a digital camera. So I took the virtual wall and in a dark room turned it on with its Ir led facing the solar panel,,the panel was connected to a meter,,and you can see how each time the virtual wall is turned on the meter shows voltage from the solar cell and that reading goes off soon as you turn the virtual wall off or face it another way..Very interesting I thought..

If you think you may be right you need to keep pondering it. I still think there is more going on than meets the eye. I will say this. Ive taken two aaa batterys and put the same polarity's together and measured the voltage. With the positve the voltage reads over 100 millivolts with the pos sign. The neg polarity's read exactly the same but with the neg sign. The amps were .2 microamps. Not even close to being one microamp.
This is still very interesting.

Electron's have, and always will travel in opposing directions on the same conductor, period.

That said, put two diodes in parallel ,
on facing one way,
the second the opposite.

Place this bi-directional gate into the center (green) wire
then measure the voltage drop across both diodes and see.

better yet, use an oscilloscope,
and watch current flow in BOTH directions simultatiously...

Please note, in a perfect world, and a perfect resistive network,
as in poynt99's textbook example above, no currunt will flow.

All respect meant there .99, but this example isn't
a "Static" purely resisitive experiment however.

Nice nick BTW, good word-play:
http://en.wikipedia.org/wiki/Poynting's_theorem

But in the real world these motors will draw and release (BEMF) current
in both directions in that center-tap green wire that can be observed.

This is most notibly used in the RF field with many items
that need to be remotely powered from a distance,
but use the same conductor as the RF return path as well,
like mast-mount antenna preamps, many marine products too,
such as the very common mod e2matrix observed.

The DC rides the core to to the preamp,
the RF rides the skin-effect back to the decoupler.

Can electrons flow in opposite directions on the same wire ?
YES, 8) off course, 2 years ago I have reproduced radiant energy experiement something like "Imhotep Radiant Oscillator" using a battery oscillating transistor ignition coil and some CFL and flourescent tube... Whith the skin effect while DC or low frequency flow from battery and at the same times light on the CFL in every connection of the circuit (even on the same polarity !!!)... Curious RF phenomena :o
