"It takes it's last drink" That sound so, so sad

8:57 "The reason the bird drinks the whiskey faster than water is because ..." I was SO hoping that Bill was gonna crack a joke right there, haha. But he kept it legit.

This whole time I thought the bird wore a top hat because he was classy.

He makes engineering and science interesting, That’s the sign of a great teacher

You can't get any better than this. Bill doesn't waste one second with ads, outros, fluff, etc. This is a perfect example of how KZfaq content out matches television content.

I could listen to this guy read a phone book.

Exactly, no fluff, no ads, no BS, right to the point, so nice someone that makes a video for others to enjoy.

This is a great channel. I am an AC/refrigeration technician, and I am passionate about my work and the science behind it, and I can’t tell you how much I appreciate finding other human beings who are passionate about understanding how things work. I wish more of my customers were as interested as us. Thank you.

no, the bird is an alcoholic and needs help. #helpthebird

"The reason the bird drinks whiskey faster than water, is because he's an alcoholic"

I drink whiskey faster than water too, I just had no idea it was thermodynamics related, lol.

I have never had more fun finding out the engineering reason of why this bird is alcoholic

"ITS DRINKING THE WATER!" -Homer Simpson

He takes a whiskey drink, he takes a water drink ... He gets knocked down, but he gets up again

We had this toy at my aunt's house and it fascinated me. Nobody in the house was ever able to explain it to me why it works like that. Once I sat with a watch to find out time between the drinks (i thought there was a timing mechanism in the toy) and yes i was wrong. Every summer vacation when we visited them this toy hypnotized me.

I am a Ph.D. engineer and scientist. This is so cool. It made my day, thank you! I have never had a drinking bird, but now I will get one. That, and a lava lamp. 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!

8:53 or maybe the bird prefers whiskey

He tip He drinc But most importantly He make you thinc

My head is a heat engine too, especially when it's soaked in bourbon. And I've been called a bird brain as well. This is the story of my life.

Bill's whole style is so concise but still elegant. I never find myself left with unanswered or incompletely answered questions, but he does it all while staying affable and never condescending, and he brings in just enough fun trivia and colorful demonstrations to make the material feel appealing. The amount of care is palpable, and the information is paced perfectly. I feel really lucky getting to watch channels like this.

WELCOME BACK

That was far more interesting than I thought it would be. Given the channel, I'd expect nothing less.

He hasn’t posted in 2 years but I just subscribed and turned on notifications in the hopes that he’ll post again. Now THIS is content! He explains everything in an understandable way, but without dumbing it down so much that it’s patronizing. Seriously great content.

This is by far the better bill who teaches us about how the world around us works.

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

Wow welcome back. So glad you have put another video out :)

I'm 62 and had a pair of these as a kid. I spent many hours in a trance watching these.

I was still a little flabbergasted until the moment when you mentioned that because the bottom ball is at lower than ambient temperature, it's heated by the surrounding environment. That snapped everything into crystal clear understanding. Fantastic video!

This video is on the Wikipedia page.

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...

Thank you, Bill. My family had one when I was a child and I was fascinated by it. My daughter recently bought one for me for Christmas. Your well thought out and articulate video allowed us to all the more fascinated by the science behind it.

Thank you for solving the mystery of my childhood after 30 years, I was still thinking about that

I'd prefer whiskey too if my belly was full of methelene chloride!

Never thought a simple toy was so interesting. Great video.

This guy needs to get sponsored by someone to make videos like this full time. He is the paragon of engineering teachers.

In my childhood my father gifted me this drinking bird.. It is still resting in my house..

Yay, so glad to see more of these videos again!

Best... Science... Voice... Ever! I always wondered how this worked and you explained it perfectly. Great video! Keep up the great work brother!

I had a dream about Dippy Bird the other night. My Granny had one when I was a child and it’s such a treasured memory of mine because I loved watching it and trying to figure out how it worked. I just received mine from Amazon today and as I watched it drinking, I decided to look up how it works. Thank you for explaining something that mesmerized me as a child. At 37 years old I finally know how Dippy Bird functions and I’m even happier that I bought it.

Currently have this toy sitting (something I bought at a science museum) at my desk and Ive noticed heat and pressing against the bottom seems to push the liquid upwards, and something about the face being completely wet attributing to the liquid constantly being pushed up and down but had yet to figure out why. This video pretty much answered every query I had about the toy and now I love it even more

The best kind of surprise.

Who wants The Engineer Guy to upload more videos?!

The bird drinks more alcohol than water is because he’s trying to forget

This " toy " brought back so many childhood memories! Thank You So Much for the Well Researched tutorial! ♥️🌷🕯

Just discovered "The Engineer Guy" channel while searching out vintage Airship. He videos are not only jaw-dropping, but he is an excellent speaker, and obviously, capturing author. I cannot wait to view all of his vids, and read some of his books.

Maybe Whiskey bird drinks more because Karen took the eggs.

Love your vids, my dad was an aircraft engineer and was always seeding my curiosity re manufacturing. One I remember well was aluminium cans as he was fascinated with their manufacture. He had well retired when they came on the scene but he understood the difficulties involved. I'm glad I've subscribed your explanations are first rate

Thank you for the video. Unfortunately basic engineering was taught years ago in primary and hi school. Now kids come here to see how things work and no doubt, like me are amazed. The Radiometer is another classic piece of engineering.

I guess your kid is old enough now to allow you some spare time for these amazing videos. Welcome back sir.

I’m not actually sure why anyone would dislike this

Man I needed a teacher like you back in high school.

This is the most insanely methodical explanation for such a novel trinket. I worship it. Also the science that goes into this is way way way more extensive than I could have possibly deduced

who would win ONe of the greatest minds of all time or A bird.

Finally, happy to see you again

Great video! In summary, evaporation occurs in the head of the bird when it wets its beak. Therefore, the head of the bird becomes colder due to evaporation. Water always flows from high to low pressure. In this case, the tail has the higher pressure since the water begins to slowly work its way up the tube. Temperature and pressure are directly related. If the temperature drops, the pressure will too. As stated before, the water will flow towards where the pressure is lower, causing the weight of the bird's head to increase, dip back into the water, and repeat.

What an awesome channel to find. This was so informative. If all schools taught this way, it wouldn't be too hard to learn. Special with that magical voice.

.... It's DRINKING THE WATER! This is the greatest invention in the world!

Thank you for the thorough explanation of how the Dippy Bird or Drinking Bird works. I used to watch these when I was a kid and wondered why it would do that. After all these years, now I know. Thanks for posting this video and thanks for being a smart man! Your education has benefited you well!

So glad I've found your channel, I'm really enjoying your presentation style and the learning process here. Many thanks!

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.

5:35 So you flipped the bird ?

Wow that was worth the wait, excellent job guys!

Simply complicated. This has been my TED talk on the topic of TheEngineeringGuy

So soothing to hear your voice explaining the fundamentals of engineering, looking forward for your future videos!👍

Now I know why Homer was so fascinated by this

Phenomenal production, amazing presentation. Thanks!

Bill has a very soothing voice and a clarity that makes complicated subjects very understandable. What I *DON'T* understand is why anyone would give this video a thumbs down.

Best narrator of the 21st century. Love you Bill

If Bill was my science teacher back in school I still would not have listened. That’s because I was an idiot at school. But at 50 I’m listening now and it’s wonderful. Great stuff Bill.

i love how it's still referred to as "the bird" even when the felt covering is off

Bill your channel is the top of class of KZfaq. Thank you

Now this is how science and engineering should be taught in schools, very well done engineerguy!

LOVE this. Can you do one on Pullback/ Friction and Wind-Up toy cars?!

This bird caused a major nuclear incident in Springfield.

Not only do I love these videos and the production thereof but the lessons/information is fascinating too. Thank you for sharing your knowledge and I"m grateful for HOW that knowledge is shared as well.

What a beautiful demonstration of thermodynamics. Thanks.

This bird and I have something in common, I drink whiskey faster than water also.

mate thank you for making another video. I massively appreciate it.

Unbelievable. So much thermodynamics in such a simple toy.

Just discovered your channel, I absolutely love the videos! Can’t wait to binge watch them

This thing was responsible for almost causing a meltdown in Springfield!

8:24 you can tell he was trying so hard to hold in his laughter :)

My first though was sterling engine. When you talked about thermodynamics I was sure of it. Gotta love the simplicity of thermal expansion.

I’m a bit late chiming in here and extremely glad to see this video. I remember when they came out in the mid ‘40s and fascinated me to no end. The bird that I remember was different than what’s in the video, but you would not have been able to demonstrate on that one. There was not plastic, no clear tube, no stamped parts. It seems that I remember more of what it wasn’t than was. Your bird is perfect for demonstrating. Thanks again.

That bird has a drinking problem

It's christmas all over again-- Bill uploaded another video!

I've seen this channel for a while with quality content, here and there, over time. I was sure this channel would have at least 2 million subs. Unbelievable the channel hasn't broken 1M.

Always wondered how these worked as a kid in the 60's. Thanks.

I guess that bird and I have similar tastes in drink!

Finally YT recommended me something meaningful.

Fascinating video, thanks for taking the time to produce and then uploading it.

Great channel to find. Love no ads inside video. Keep up the great work. 👍🏻👍🏻

I just bought one of these after seeing it on The Simpsons and being hit with a wave of nostalgia. I always wondered how these worked! It was like magic to me as a kid. Excellent video, thank you Bill.

I want one of these!

This is great. The explanation and the visuals were top notch.

There's more at play here than I expected. Love your videos!

Step 1: construct bird Step 2: compel bird to drink Prosper!

Would like to see your explanatory video about Stirling engine. Please!

How fantastic! Lovely explanation, as always Bill! Thanks.

Fascinating video. Brought this bird after watching it. Put it into action and found out the bird's motion is intricately connected to the weather conditions. Another video on it please.
