Hello Steve,

It is simple. On a PCB select an area where two conductors are running parallel to each
other. Connect a  power source through a rheostat. Apply some water drops so as to
cover two tracks. Tap water will be fine. Increase voltage slowly and you should see
migration growth ( depending conductivity of water which you can change by adding
common salt to water). Have fun.
