Neon is an element which makes sure that we can have those huge billboards in Times Square.
As well as being in pizza signs and such, neon is also the second noble gas element. This means that it gives off a red glow. In fact, not all neon signs are made with neon. Some use different noble gases for a different colour. Usually, it's just the red ones.
It has also named a template, which is being used right here to make this article concerning neon look less generic, and more self-referential. Silly, isn't it?
Installing it in your home
Generally, since it's a gas, it will escape if there is no safe container to put it in. Said container is usually a series of tubes, which let the gas flow through and out.
If you own a pizza place, then stick the sign outside. It works best if the tubes are shaped to say the word 'OPEN', which flashes on and off as people drive by.
None to speak of. I mean, inhalation could be dangerous, but who's going around inhaling neon gases, perhaps for a legal high? Just tell me.
- Helium, however, is transparent, and therefore too boring for us to think of it.
