The Chatterbox tube is a wacky way to educate young scientific minds about the properties of air pressure, sound and even lung capacity!

This 'Bright Spark' experiment guide has high definition pictures that show you all the steps in how to investigate the power of air. It provides you with a complete explanation of the science concepts this tube can teach (air pressure, Bernoulli Principle, Pascal Pressure and more). It has a section that connects other experiments and how to change variables to make your investigations 'scientific'. Great for school projects.
