A Long Lens


This week we will see that you can do science experiments anytime, even while cleaning out the refrigerator. Well, to be honest, it distracted me from cleaning out the refrigerator, but eventually the job will get done. I
promise. I really do promise. To avoid cleaning your refrig.... I mean to try this experiment, you will need:

CD Spectrum

This experiment uses a computer CD or DVD. If you have ever looked closely at either a music or computer CD, you have probably noticed that they produce rainbows. If you hold the CD with the shiny side up and let light from a lamp reflect off of it, you will see a very nice rainbow of colors. If you are using a regular incandescent bulb, you will see all of the colors of the rainbow: Red, orange, yellow, green, blue, indigo, violet. If you use other kinds of bulbs, you may find some colors missing.

Bubble Colors

I came across the idea for this while searching for the website of Tom Noddy. Tom is the original bubble man (and in my opinion, still the best.) He planted the seed for my decision to go into business for myself. I met him while I was working at the Memphis Pink Palace Museum. He was doing a weekend of shows at the museum and got to see me doing an electricity show. He told me that I should take the show on the road. That was back in 1987. It has been a long and wonderful road so far, and hopefully it is far from over.

Bouncing Remotes

This experiment comes from spending too much time in hotel rooms as I travel. As I was packing for the trip home, I found a very useful technique for adjusting the television when I was not directly in front of it.
