Demonstration
Exploding bubbles of hydrogen and oxygen

In association with Nuffield Foundation

Create a small explosion in this demonstration by electrolysing water to produce hydrogen and oxygen bubbles. Includes kit list, video and safety instructions.
Demonstration
Electrolysis of molten zinc chloride

In association with Nuffield Foundation

Try this demonstration to show how an ionic salt will conduct electricity when molten but not when solid. Includes kit list, video and safety instructions.
Resource
Hand battery

In association with The Solar Spark at the University of Edinburgh

Complete a circuit by placing your hands on two metal plate electrodes.
Class experiment
Exothermic redox reaction of zinc with iodine

In association with Nuffield Foundation

Using an exothermic redox reaction between zinc and iodine, student will make zinc iodide. This can be reversed using electrolysis to decompose the compound.
