The Engineering of the Drinking Bird

Ғылым және технология

Bill reveals the operation and engineering design underlying the famous drinking bird toy. In this video he explores the role played by the water the bird "drinks," shows what is under the bird's hat and demonstrates that it can operate using heat from a light bulb or by "drinking" whiskey. You can find more of Bill's videos and his books at

    @August Greig there as Peru or Ayahuasca? In Lima yes, other places can't tell as I don't live there nor travel much, but from here and other 3rd world countries is that most raw food are brought from, so I'd say yes. Just be sure you have to know someone from here that isn't white. Merchants in touristic places tend to over over over price things when they see someone white.

    @August Greig nothing beats that you first described, the 15s ads that can't be skipped followed by a second ad of also 15s. Except if you're in Peru or idk if it's region exclusive but I had many instances of over a minute long ads that didn't even have the button to skip, I had to watch the entire minute and below said (1 of 2). Better just press F5 and reload the video . Or when you're using KZread for a party and leave a playlist, those hour long , and I don't joke about this ,HOUR LONG Indian ads of music or trailers, they do fuckin actually last over an hour. And you have to find the stereo with the 💻 hidden from the people so they don't drunk-tackle it. Really makes you wanna download the videos in mp3 format with something like Force-download or another free download service online. I know in Burgerland is like a big deal to "illegally" download music so you're forced to pay for stupid shit like Spotify or other Google Music Garbage, but here in Peru they don't give a fuck. You can download whatever you want and nothing ever happens... So if you ever wanted free music, that's an option. I heard each song can be like a dollar? With 2 playlists that's more than a ticket to Peru or other 3rd world country with internet that Burgerland doesn't care about

I would like to see Bill do a video about lava lamps. They are similar in that they are heat engines relying on a temperature differential and changes in buoyancy resulting from temperature dependent changes in density. Though I know how they work, I would love to see Bill explain them because his presentations are so captivating!

    I cannot explain how wonderful this video is. "Don't touch the birds, " with an angry dynamic New York City accent". My father sold these birds at many different flea markets in the USA. He did not only sell the birds, he entertained thousands of people while doing it. Well entertain is somewhat not a word that describes his presentation correctly. He did not explain the physics of the drinking bird toy, nor did he do a dog and pony show, or a stand up comedy routine. The best way to describe his Drinking Bird Show is simply that it was his unique behavior, his very short-fuse temper, and his unusual mental state. My father was basically a very intelligent guy however, he was extremely crazy. He had a personality that was extreme and to say he lacked patience would be an understatement. He could not deal with things that other people found easy to accept. He had no tolerance for maters that displeased him and when a child or an adult became fascinated with the drinking birds that he had on display in a more or less uniform military arrangement he would blow up screaming, his rant, yelling as if it were opera "don't touch the birds". His startling reaction was received by people in odd ways, some were offended, some were amused, and some were shocked. He just could not accept the fact that he could not sell thousands of those birds every day and of course he just could deal with the financial losses he had as countless drinking birds would fall from their perch and become very damaged drinking birds when they failed to fly or otherwise escape their fate, crashing to the floor. He was quite an attraction and people would come to the flea market expecting to see his "performance". He wasn't appreciated by everyone due to his offensive mannerisms which resulted him being kicked out of probably every flea market in the USA for this and other crazy behavior. From as far away as the other end of the swap meet his rage could be heard loud and clear, "DON'T TOUCH THE BIRDS". I am going on eBay to buy one right now.

    Welcome back! I first saw one of these toys when I was very young. I was mesmerized, and my dad tried telling me that the bird was solar powered, with the batteries kept in the hat of the bird. I was a bit too young to come up with a solid hypothesis on how it worked, but I knew my pops was wrong. I tried telling him that the liquid in the bird was key. I have thought of this toy over the years, but surprisingly never bought one, since I have never even seen one in real life again. I never thought of looking them up on the internet for some reason...

    Interesting.....Since long I was wondering what engineering is behind this model....Thanks a lot for explaining

    I always wanted to know how this works. As a kid I used to watch this at lot, in our neighborhood grocery store.

    I was hoping for more detail of the pressure cycle and how the oscillation continues for multiple cycles after removing the external temperature differential. On the outro topic, I never understood how Otto cycle engines are classed as heat engines rather than chemical engines, as some energy comes from changing the number of gas molecules through combustion.

    Our 3rd grade science classroom had one of these and every once in a while the teacher would place some water in front of it. I would sit and wonder how it worked, 50 years later, thanks to you, now I know. Thank you

    I got one of these from a Vsause Curiosity Box for my daughter. I didn’t work all that well. Tonight, curious myself, I gave it a try with a shot of whisky, rather than water; it went crazy. My initial conclusion: these things like drinking whisky more than water. But really my conclusion: the rate of evaporation of the liquid in the head determines the success of the action. But also really my conclusion: I don’t actually know how this thing works. This video answered literally every one of my questions - excellently done! Most importantly, why does my Vsauce toy not work all that well? Because I live in New Orleans, where the average humidity is something like 75%. Well, there you go; a scientific explanation for why I should not complain about something I bought for my daughter. Excellent video, covered every specific question I had, more or less in order, without knowing my questions in advance. As the bird might say, hats off.

    In the 80’s I put one of these bird on my computer monitor... just like the heat lamp the monitor supplied heat to the bottom bulb and the bird operated....a computer scientist friend saw it exclaimed it must be perpetual motion because he knew that “for a fact” the bird needed water to move. He quickly concluded I had filled the bird with some special mixture of water and proteins ( I had talked with him about how proteins fold and unfold) ... even after I demonstrated turning off the monitor stopped the bird he still believed it was energy for free ... clearly he claimed I had switched birds when he wasn’t looking... he was upset for years because I would not accept an investment to get a patent...

    The reason the bird drinks the whiskey twice as fast is because it thinks it tastes better. That's just science.

    You can compare it to one of these so-called "love meters" which is just two bulbs full of Methylene Chloride with a tube going almost to the bottom and a fountain in the top bulb. You heat the bottom bulb with your hand and it supposedly measures just how quickly you fall in love. But it is really the same thing as the drinking bird where there is a heat difference between the two bulbs causing vapor to expand in the bottom bulb which is where the real action takes place.

    I used to be fascinated by these birds in the novelty shops on the boardwalk of Seaside Heights, NJ as a kid and could never figure it out. But now as an adult as soon as you revealed the evaporative effect on the head - I thought, my god it's a Sterling Engine! And I kick myself for not making that connection back then because I had another example of this thermal effect in a model airplane that ran on carbon dioxide expanding from a seltzer bottle cartridge. Thanks for solving this 66 year old kid's mystery.
