Sounds ok but not sure how many dollars I have. My son liked it but lost
interest in a few minutes. Maybe I was hoping for a more exciting review
form him

O.K. kids, see this loop of wire? It's a closed circle right? Who can tell
me what's happening in this closed circle of wire right now? Any ideas?

Ideas follow.

Well who said nothing? Well, you're right because nothing is happening
inside this loop of wire at the moment. It's just a loop of wire, made up
of a bunch of copper atoms. All the copper atoms are just sitting there
looking at each other and nothing is happening. Atoms, by the way are the
small pieces of copper that exist, so small, you can't even see them in a
regular microscope.
But here's something really strange, if I take a magnet and pass it
through this loop of wire, something starts to happen. Anyone know what
that is? You there in the back, pay attention because I was just telling
everyone else what Santa Claus is giving you for Christmas. Sorry, I only
mention these things once. Who can tell me what happens?

Ideas follow.

Well, what starts to happen is that these atoms start passing parts of
themselves to the atom next to them. Here, each one of you pick up one of
these stones I brought along here and get in a circle. Now pretend this
stone is part of you. We could call it your arm but you already have one
of those, so we'll call it your electron and we'll pretend you're a copper
atom in a wire. Ready? Now here's what we're going to do: When I shout
"magnet!" each one of you guys is going to take this small stone, and pass
it to the person on your right. Who knows which direction right is? (Sort
them out) O.K. ready? MAGNET!!!!!

Hopefully, all stones move to the right.

Now what you've just done is demonstrate what happens when a magnet
passes around a wire. Those electrons moving are called..Who can tell me.
Tell me and I'll pay you a buck right now.

Good. That's right, electricity!!!!!!

Now what I've got here is a little device I made to make a whole bunch
of magnets go past a loop of wire real fast. It's called a generator. Here
you there. Turn this and let's see what happens. See what those moving
electrons can do!!!!! Very good, here's a buck. You generated electricity,
just like the power company, so I'm paying you just like your folks pay
the power company to keep your lights at home on....
