Electric Tape

I really wanted to use the Electric Tape experiment for a video, but the sparks did not show up enough on tape. Until I can afford one of the new, super low light video cameras, we will have to get by with reading the text version. After the recent news articles about producing x-rays with adhesive tape, I thought it would be fun to do an experiment that would help explain how it works.

Lightning in Johnson Canyon

This week we had a marvelous electrical storm to the west of our house. It was far enough away to make Junie Moon the Dog happy, but near enough for some nice photos. Since it was night, I used the same settings that I use for star photography. I put my Nikon D7000 on the tripod, with an 10-70mm lens. I set it for manual exposure, and set the shutter for a 30 second exposure, and turned on long exposure noise reduction. I hooked up my PClix, a marvelous device for taking photos at set intervals. Then I just let it click away.

Balloon Chase

This experiment is one that I played with while waiting for the time for my Electricity show to start. I started with one balloon, and then added another. Then I began experimenting with other materials, and managed to pass the time very quickly.

AM/FM Radio Waves

This week's experiment comes from a question that I received about which is better, AM or FM radio. As we shall see, the answer depends on what properties you are basing your answer on. As we will see, each has advantages and disadvantages.

Electricity

This is the Watt is Electricity show that I toured the country with for over 25 years. It covers the basics, including electrostatics, volts, amps, alternating and direct current, making it a great place to start as you study electricity.
