Bird water whistle's have a really interesting mechanism. I made a 2D transparent version so you could see what's going on inside. I also explain how whistles work. Including the kettle whistle.

    The Peruvian Whistling Vessel video should be out in a few weeks. Consider clicking the notification bell if you want to be sure to catch that one. The sponsor is Wondrium. Signup for your FREE trial here: ow.ly/O6AN30siJKg

    Presumably, the type of bird that would sound most like a “warbling whistle” would be a warbler, surely?
  • I love these 2D cut-outs, really makes the explanations more intuitive and easier to understand!
  • 9 minutes in and you've explained 3 questions I've had my life. How do we whistle with our lips? The tea kettle. How does blowing a blade of grass work? Holding a blade of grass in the wedge of your thumbs.. The wedge method. And how do birds whistle, if they don't have similar equipment as us? The bird whistle is their belly. Madness
  • I have a whole new found appreciation for whistles now. My son LOVED learning about this and so did I! My son was using his whistle while watching this and got so excited when you finally addressed his sports whistle. Love how even the simplest things have an element of physics to them
  • @GadgetAddict
    You're a genius for coming up with these clear 2D representations.
  • @Olodus
    I was about to ask Steve how a normal human whistle works, but then I got scared he would make a 2D transparent version of me!
  • @Tehn00bA
    There's also the scary aztec death whistle that makes a screaming sound, along with other whistles (like hunting ones)
  • @MattRose30000
    6:00 reminded me of the "grass whistle" where you blow on a blade of grass that you hold tightly between your thumbs. Probably works the same way.
  • @sariya74
    I remember seeing these warbling whistles everywhere on markets in my home town. I absolutely love these things
  • @furzkram
    Like a "normal" whistle, the second / outer hole on the kettle whistle has a wedge that is hit by the air stream - this edge goes all around in a circle.
  • @anemoiacApache
    Steve breaking out into a giggle at "corrogaphone" is hilarious.
  • I had one of these as a kid in the 70s I always wondered about these... I love the fact that you explain it easy enough for people like me to understand ..and yet don't dumb it down for more intelligent people. Sign of a good teacher .♥️♥️
  • What a great explanation of whistles, I've wondered about this my whole life, and describing the effect with visuals really brought it to life for me.
  • @TheMetalKiwi
    I literally never saw one of these before until today. I was visiting a museum gift shop with my fiancee and we saw a cute little purple jug and decided to buy it for a friend of ours as a souvenir, and then the guy who works at the museum goes: "Do you know what this is?" and proceeds to show us how to work it. We were blown away, like a couple of kids! Not 6 hours later, I come home to this gem of a video. 😁
  • @xilm22
    my 22 years of curiosity of how a whistle works finally cured
  • @doomakarn
    A whirly tube is just a Helmholtz resonator. As it spins around, the air passes over the hole; but air does not travel throughout. Theoretically you could just attach a string to a bottle and swing it around and get the same noise as a whirly tube.
  • 2:44 Another interesting bit is that many american WWII fighter planes make a whistling sound while they're in tight turns. This is the exact same effect as the corrogaphone as air is passing over the barrels of the M2 Browning 50. Cal guns.
