We at guernseydonkey.com are always keen to promulgate that ever exapanding ‘body of knowledge’ we like to call “intenet fluff”. Accordingly we recycle here for your delectation a story that seems to have begun its life way back in 1997 when the internet was still young.

Scientists in Zurich, Switzerland have up with a sensitive new way to analyse the composition of almost any surface, including human skin by blowing a stream of nitrogen across the surface under analysis and collect the gas together with any debris that it dislodges. The material is then fed into a mass spectrometer that can pick apart the chemical composition of anything present on the surface.
A bar of soap is a chemical miracle – a little scented block that unleashes molecular forces when dunked in water. In this article we look how this little miracle actually works.
Fire – one of the most primitive and yet intriguing of the ‘fundamental elements in our world.
