Let the particles do the work, part 2
CLEAPSS devised a simple small electrical conductivity indicator. The resistor in the circuit limits the current to protect the Light Emitting Diode (LED). The carbon fibre-rod electrodes are very strong unlike graphite.

It was originally designed for our primary section at CLEAPSS who thought it might be useful for straightforward investigation of what conducts electricity what does not. However, this little piece of kit has grown in value in my estimation over the past years because it has given me a greater insight to the nano world where all the chemical action takes place.
