**"NEON" **

You may wonder what makes neon signs so appealing and bright?!?! Well that comes from "fill" gases nsuch as Argon, Neon, and Helium. The process involves these gases being placed inside of a vacumed tube with electrodes on each end for electricity.This will help you get color and illumination. As far as the different colors go... Neon, when illuminated gives off a red color. Argon and helium are combined to make blue light. Argon and helium are put together for the amazing "glow" seen in fluorescent light. This is with the help of mercury also. And that is what goes into the attractive neon signs that you see on the streets!!
