Exhibition Chemistry: Floating gas bubbles

Description

This demonstration is enjoyed by all ages, but is particularly useful for Year 8 students when studying the properties of gases. It helps to reinforce the idea of density, which can be related to methods of collecting gases (upwards displacement of air etc), and to enforce the idea that gases, despite many being colourless, still have substance.
