On this quick from the Royal Establishment, the supplies scientist Anna Ploszajski combines her best passions – physics and music – in a extremely entertaining demonstration of how her two areas of experience are inherently interconnected. Blowing a trumpet into a tool often called a Rubens tube, which visualises sound waves and stress with flames, Ploszajski exhibits how, for all its complicated engineering, her instrument of selection is, in essence, vibrations created with the mouth travelling by a tube. She additional deconstructs the instrument by exhibiting how blowing into concrete, ice and even jelly can generate a really comparable impact. Ploszajski then ends her presentation with a quick historical past of the trumpet from historic Egypt to right this moment, exhibiting how the instrument has developed alongside modern expertise, even because the physics of the way it creates sound has remained very a lot the identical.
