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.
In this experiment, students observe as water is electrolysed using sodium sulfate solution. The electrolysis produces the gases hydrogen and oxygen, which are allowed to mix and used to blow soap bubbles.
