When I was an Elementary Science Coordinator, I used to visit the five schools in my district and each year introduced the Pringles® Kaleidoscope as part of the Sound and Light unit. At that time I used microscope slides, and it became quite a challenge to have the students line up and tape nine slides to make the triangular prism. Fortunately, Educational Innovations began to carry Kaleidoscope Mirrors (SM-3), thus making the task much easier.

Ahhh, Eddy Current Tubes – you would never think that a hunk of copper pipe and a magnet could make anyone grin from ear to ear. I just love these things.
So simple in appearance, and yet so magical to see and use. Whenever I happen to have a set at home, I soon lose control of them to my wife who is just as fascinated by them as I am.
Although they can be used in fairly high end physics demonstrations, they are stunning enough that everyone who has a chance to see them is simply amazed.
Just realized – you may not have not seen one, have you? Here’s a video for you:
Kinda cool, huh? So, since I have (hopefully) gotten you to say “wow,” I’ll just bet you are wondering “why” — here’s some science:
