Chemists in a BiG WoRLD:
Neon Signs


I know it's annoying, but at least you will be able to spell "welcome" for the rest of your life.

Neon signs are those bright-colored, sometimes flashing lights that are commonly found in store and restaurant windows. And you may think �Oh, that neon! He�s so bright!� Nevertheless, don�t be fooled. Those bright signs commonly do contain neon, but in many cases other Noble Gases are used too, like Argon for instance. Please, don�t give all the credit to Neon!


This could be neon, but perhaps it's argon, no?
Either way, he resembles Korin... in an odd sort of way.

Ok, now that neon�s fraud has been exposed, we�ll go over the chemistry of these impressive glowing signs; after all, it is a kind of chemistry that makes them so lively in color. The gases in these tubes (for now, we�ll just call them neon, or �the gas,� or �the gases�), can last much longer than light bulbs. This is because of the way �the gases� produce their light. Instead of heating a filament, like in light bulbs, neon light is actually produced by passing a high-voltage electric current through a glass tube filled with an inert gas � a good example is (you guessed it) argon and mercury.


Pretty birdy thingy and crab, eh?

Each different gas has its own color when electrified, but other elements can also be added to the gaseous mixture to produce different colors. A good illustration of a mixture can be found by adding mercury to argon. Instead of glowing dark blue, when argon is mixed with mercury, it tends to be a much lighter brighter blue. Another way you can change the color of the tube lighting is by using different color glass tubes or a power that can be put on the inside of the glass to make it fluorescent. By using a combination of different gases and different glass colors/powders, many different colors can be achieved. The number of different designs can be attributed to the ease in which designs can be made. The glass tubing can be intensely heated, making the glass molecules soft and pliable. From there, the glassworkers can bend the tubing into whatever shape they desire. A multiple colored neon sign is simply a system of various glass tubing with different gases or colored glass on each one. Store owners and sign makers can make the signs blink by making the electric current stop and start at constant intervals. As the electricity stops, the sign goes dark, and as the electricity comes back in contact with the gas, the sign lights up again.


Like, whoa. Doesn't this fish look a lot like Ben Tietze?

A little history about neon (and the other friendly glowing gases):

Inventor Georges Claude produced the first glowing neon light in France in 1910. Patented in 1915, the neon sign attracted so much attention when it was used in a sign in 1923 that it is still one of the most popular and attractive materials to create signs out of today. Throughout the 1950�s and 60�s, and even today, the demand for neon and gaseous signs are very high.

The following may be offensive if you like the Yankees. Be advised. However, it is another good example of a neon sign.


I'm a Red Sox fan, this is just my opinion.
If this is offensive to you, or you are a Yankees fan, I'm sorry. I really am.
New York is a great city, I just hate the Yankees. With a passion.

Lela once told me she was Irish. What do you think?
At this point in the presentation, everyone should turn and stare at Lela.
If all goes as planned, she'll turn very red and it will be funny.

A few simple things we learned:

  1. Neon is fraud, because often Argon and other noble gases are used too.
  2. Neon (and other gases used in signs) glow because of an electrical current.
  3. The New York Yankees suck. Really, they do. Ha ha to you, Thomas.
  4. Since the Yankees suck, the Boston Red Sox are automatically the best.
  5. Korin is funny, both in appearance and personality.
  6. Lela is Irish (we think).
  7. Miner can sing "Crystal Blue Persuasion" really well.
