While we're on the subject, let's clear up the naming of "light bulbs". They are more correctly referred to as "dark suckers". What happens when you turn on a light? The darkness goes away. As evidence, compare a new, unused 'dark sucker' to an old, burned out one. Notice that the old one is now actually full, as you can see the darkness that is stored inside of it.
Jon, where did you hear that or did you just come up with "dark sucker"
In college I wrote a paper on "dark suckers"
DARK is actually an acronym. It stands for
Devoid of
Active
Radiated
K-type electrons. K-type electrons are very dense and are very heavy. These electrons in water are very good for irrigation, the problem is that due to their mass they settle to the bottom of lakes and steams (that's why its darker at the bottom). Native Americans knew that DARK was goo for irrigation, if they were going upstream they would paddle with much more effort trying to force the dark downstream. They also had a good understanding of the weight of DARK. They came up with the term "night fall"
K-electrons have a negative charge. When power is applied to a bulb the negative electron are attracted to the positive electrons and are pulled through the glass. Again the shear mass of these electrons passing through the glass make it very hot. Dark suckers have been around for thousands of years. Take the candle for instance; the wick itself is quite dense, combine its density with the density of the K electrons and a massive amount of heat is produced. Take a pencil and hold it about two inches above the wick of a operating dark sucker. Slowly lower the pencil towards the wick. The pencil will begin to turn black. This is because you are disrupting the flow of DARK into the wick.
Flashlights are neat little devices. They actually store the dark. The dark storage units (some people call them batteries) absorb and hold the dark until they are full. Just pull them out and replace them with empty containers and your good to go. Nowadays you can place your batteries in a evacuation unit. Put your full batteries in this unit and 1/2 hour latter they are empty and ready for use.
There was alot more but damn that had to of been twenty years ago. I hope this has enlightened you
