Real looking magnet motor with good explanations.

                                           Continuously self adjusting balance wheel.

Seeing for one's self if it works or not, is to know with certainty, that it
works or does not work.

Seeing for ones self,  also opens up of a possibility of understanding why
it works or doesn't work.

To SAY that it doesn't work, is not the same as knowing for certain that
it doesn't work.

Knowing for certain that it doesn't work, is not the same as knowing WHY
it doesn't work.

                                 The reason why it doesn't "work".

      The net balance, left and right of center comes to zero during the rotation.
          Otherwise the device would stop rotating almost immediately, except
         that it would first oscillate (like a pendulum) for a some amount of time.

                                        The wheel eventually stops rotating.
                  If the rotational position of the wheel, at which point its rotation stops,
                  is used as the starting position of the wheel, the wheel doesn't self start.

                             Energy must be input into the device to start the rotation. 
                        This is accomplished by a manual rotating of the wheel into its
                                                        "starting position".
                                    One lifts a portion of the weight in the bottles.
                                           That input, unbalances the wheel.

                  Even though these kinds of devices are commonly referred to as
                       "over balancing wheels", they are in fact self adjusting, such
                      THAT BALANCE IS MAINTAINED, throughout the rotation.
                  EXCEPTION... There are waves bouncing to and fro in the bottles
                                         (In English  the fluid is sloshing about)

                                             The force of the leverage....
              which is a combination of weight and its distance laterally, from the center
               of rotation, is constantly shifting within each bottle during the rotation
                                                        of the wheel. 

                         The force of the leverage which is left of the center of rotation
                                                                   is equal to
                         the force of the leverage which is right of the center of rotation
                                            at all times during the wheel's rotation
                            except when first starting the wheel, by an initial / manual
                                                       unbalancing of the wheel


                                           Initially it is unbalanced, then it is balanced.
                        Although though the fluid is always shifting within the bottles left of
                          center, it is also always shifting within the bottles, right of center.

                      If such a device is well constructed,  i.e. the bottles are very nearly
                       identical in their spacing around the rim,  the bottle weight is the
                      same for each bottle and the bearings have very low friction, then
                           momentum can carry the rotation for long periods of time.

My opinion is based on observation and reasoning.  Its not in alignment with the common description of the device as an "over balance wheel". 

But also my opinion is not just another "safe bet" / low risk / repetition of rote "learning". 
Its not just a another cheap shot. 
If I take a chance I may gain an understanding. 
Otherwise what ?  I can instead regurgitate factoids, while actually understanding very little ? 
If I stick to the factoids, it makes me almost always right.

              There is some similarity in the 1st magnet / wheel device to the gravity wheel device.
                                          The question remaining of the magnet device ....
                     Is there some degree of magnetic force neutralization realized in that device ? 
                         Perhaps between a combination of the back and front faces of the rotating
                                          magnets in relationship to the flipping magnet.

                     I could be wrong though.
