WOW!  I have GOT to build one of those!--that's the most amazing use yet
that I've seen for this principle.  If I were a teacher at an elementary
school, I'd be going doubly nuts -- what a great introduction to motors!!

One tip I have for those of you who'd like to build your own magic trick.
To make sure that the electric plate is never unintentionally revealed, I
used tiles instead of bricks on parts that are meant to be taken off that
touches the gray plates that covers the electric plate.
I also practiced the trick a few times before showing it to friends.
Like they say, it's all in the presentation :-)

So, you discovered the principle of wired-together motors more or less by
accident?--then, while tinkering, and, upon realizing what was going on, • you
devised a "magic trick" to demonstrate?  That is so perfect!

I wish I could claim deep thought insights, but yes, it was an accidental
discovery.
When I was little, I did try (as probably many of you did) to create a
perpetual engine by hooking two motors electrically AND mechanically.  I
would spin the joined axles, and could not understand why the motors would
not continue to spin?!  Darn friction! :-(


Great tantalizing sequence of photos, too!  :)  :)

I've just recently purchased a digital camera (Olympus DR340), and been
taking pictures of anything within the visible wavelength ;-)
