I discovered that about two weeks ago...

I was working on my LEGO based laser light show using two motors and silver
anniversary bricks as mirrors.  I hooked up both motors to a battery box.
Somewhere along the line, I disconnected the battery box, so the two motors
are wired together.

As I was adjusting one of the "mirrors", the other mirror moved!  Freaked me
out! ;-)

Well, I thought, if it surprised me, how many people know about his
"phenomenon"?
So, I set out to create the world's first(?) LEGO magic trick!

Here's the current incarnation of LEGO Magic Trick:

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!!

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!

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