Neon is a colourless, odourless and tasteless noble gas which doesn’t react with any other substance. Its most common application is in neon signs, where the gas is placed in glass tubes and an electric current is passed through, causing it to glow red.
The gas is useful as a lighting system because it is usable in cold places, meaning it can be applied in aircraft and as a cryogenic refrigerant. Neon is also used in lasers, television tubes and in lightning arresters, used to shield electrical equipment from lightning.
This is a general science zone, where you’ll meet six scientists working in different areas.
