The Doppler effect - with FARTS

Description YT

Hello children, it's education time. Are you ready? Then we'll begin. Sound can bunch up and move apart depending on the speed and direction of the object that is creating it. Alternatively, as this example shows, the camera could be moving and the fartee standing still. Observe how it alters its pitch depending on the direction and speed that it's heading. Isn't science wonderful?!

The FART MASTER gives teachers permission to show this video in science class-rooms, but only for educational reasons. Much like he does with this other beautifully crafted bit of education about vibrations, seen below:
