The Doppler's Words
Can his words outrun him — or will they get all jumbled up?

Press Start Talking, then drag The Doppler to see what happens!

Right Listener heard: →
Try this: Start talking, then quickly drag The Doppler towards one listener. The words bunch up on the side he's moving towards (arriving faster) and stretch out behind him (arriving slower). If he moves fast enough, words can arrive in a completely different order! This is how the Doppler effect works with sound waves.
🎯 Challenge: Can you move The Doppler so that one of the listeners hears his words exactly backwards?
