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, with five scientists working in a variety of areas. One scientist is looking at how water works its way from rain, to ground, to the sea, one is studying parasites that control the behaviour of their hosts and another works as an expert witness in cases involving toxicology. There is also a scientist finding out how best to teach students physics, and a scientist finding out how our brains grow in the first two years of our lives.
