Dipping Bird Experiments (THERMAL IMAGING) - Sixty Symbols

[@Candoran2]

I like this different style of video. It's very relaxed and the pace calmly and clearly explains what is going on.

[@mojosbigsticks]

Thanks for the "can you guess what will happen next" pause. It took me right back to school and our earlier versions of interactive television!

[@Inritus618]

Really well done, I'm highly impressed with your ability to explain the system without one of the professors. I'm not surprised at all.

[@chalkchalkson5639]

This was different, but awesome! Brady you should make more videos yourself. This is my favourite video on this channel for a long time, it seems to have way higher production value and as Grey's parents will agree, you are a very likeable and relatable guy

[@celtgunn9775]

This is so fascinating to see how the dunking bird works, Thanks for sharing this with us.

[@MrJonnyk000]

I love the shot of Brady with a bank of cameras focused intently on this bird toy. Well done on the explanation! I think this might be the only video of yours I have seen which features so much of you. Nice to see you in front of the camera some times.

[@philcorrigan5641]

The style of this video (the music, the 'can you guess what will happen?') reminded me a lot of those BBC educational programmes they'd show us in school in the 1980s...

[@janeweber8654]

Wow, a Brady only video! That's new :O Different but quite cool!

[@d0themath284]

no, he also had all of those ducks with him

[@munkeyz]

Nice to see a video made merely by you! Great work Brady! :-)

[@tomwhiteley4126]

I really like this style of video, Brady being hands on is really encouraging for new science and scientists

[@gusstavv]

This video is more illustrative than the previous one. I really liked it a lot. Thanks!

[@BrunoWeiers]

Nice one Dr. Brady. You sure make a great Derk style video. It would be nice to see more of these.

[@fredlllll]

you should apply some diffuse coating to smooth surfaces like glass, so it doesnt reflect heat, and also emits more heat, so the camera can see its actual temperature

[@Tjita1]

Yeah, it's called emissivity, and glass has pretty much none at all if you don't coat it with something. If you wan't to check the temperature of a window pane with a camera for example, the simplest way is to just put a piece of painters tape on it.

[@locust76]

IT'S DRINKING THE WATER!

[@d0themath284]

no, it doesn't have a mouth or throat so that is impossible.

[@SchumiUCD]

It's going back for more!

[@Rando_Shyte]

Geez you stoopids need to bone up on your classic simpsons

[@whoeveriam0iam14222]

Brady is the professor in this video..

[@Bakeey_]

whoeveriam0iam14222 : He ain't got a doctors title for nothing!

[@tennisdude52278]

Lawrence Clarkson What did he get his doctorate in?

[@666Tomato666]

+tennisdude52278 "Letters"

[@tennisdude52278]

666Tomato666 What?

[@666Tomato666]

[@Amethyst_Friend]

Brady, at 0:35, you should say 'normally colourless'. The dyed liquid was also clear, despite being blue coloured. I know it's a little pedantic, but I remember my GCSE chemistry teacher stressing the importance of this!

[@Athanatizein]

This was really nice, Brady. Much enjoy the more personal style, and nice to have you in front of the camera over here as well. :-)

[@TheHorseHat]

This is a really great video, Brady.

[@brianpso]

Was this your idea Brady? Because this seriously looks as scientific as it can get. You sure are a star like everyone you interview.

[@davidmurphy563]

Could you perhaps show the same thing with a stirling engine? Most people would never have seen one and it'd be nice to see the thermodynamic exchange of a temperature gradient turn a wheel - particularly if you could attach a dynamo.

[@jacktumbleweed]

I'd like to see a professional glassblower make a bigger version. I wonder if there's a limit to how heavy it can be while still functioning.

[@scottramsay3671]

I love this slightly different format of video

[@MozartJunior22]

Wow - great to see that you have learn a lot from the professors!

[@DEFarnes]

Well done for what I believe to be your first full blown explanations! Good job

[@palmerjwm]

Great video Brady!

[@AdibasWakfu]

i bet the guy only became a professor to be called professor Moriarty

[@theonlyari]

Cool idea with the thermal camera. You should spray paint the bird with black spray paint so you can see the temperature change, rather than the reflected infrared light.

[@PetrFlosman]

That was really easy to follow explanation! Great video :-)

[@MarkGarth]

Anyone called Professor Moriarty gets my vote :-) Seriously interesting video.

[@Felipehez]

that's really cool brady, i would go around making experiments with everything if i had a thermal camera.

[@kpapi4355]

This must be one of the most ingenious toys considering the complexity and physics involved, I didn't buy just one, I had to buy three!

[@Nurr0]

There's something hilarious about the thumbnail for this video.

[@AlexKnauth]

This makes it much clearer, thanks for the video!

[@4jonah]

What happens if you put the tea light under the bird so it wants to stay in the "dipping" position, but it leans into ice-cold water where it will want to go back to the upright position?

[@Modenut]

Hehe I work where that thermal imager is made. Looks like a T1020 or maybe a T1030SC. Great video. =)

[@ollenmt1729]

Great video Brady! :D

[@Zemmip]

Wow that was 6 years ago... I remember watching that video when it first came out.

[@SpiderGirl42]

Look at you Brady, doing your own science :)

[@leocelente]

That was seriously awesome!

[@karlmuster263]

That last one was pretty cool.

[@vasilistoxo]

Really nice, well done.

[@artswri]

Nice! Fun, entertaining, comprehensible, educational! A+

[@AlfieM360]

I liked this slightly different style :)

[@AlexKnauth]

+

[@dumbcat]

is the shape of the head and abdomen important? and do they have to be different sizes or could they be the same size i wonder?

[@Cruuzie]

With his doctret degree secured, Brady starts aspiring to be a professor!

[@fractalnomics]

3:38 Air does not radiate; when everything else does - why? I think I know.

[@hunterdouglas9765]

This is the greatest invention in the world! You'll make a million dollars!

[@tgijc]

Great video, tks Brady!

[@Gooberslot]

What would happen if you super cooled the head?

[@Mastikator]

You mean like have a glass with liquid nitrogen?

[@42ouncesofPAIN]

What is the word he used at 6:05? I have no idea what that word is... Araprative Cooling?

[@rhamph]

Evaporative cooling.

[@42ouncesofPAIN]

Adam Olsen oooohhhh..... ok. I paused it and listened to him say that word 4 or 5 times and I just could not figure it out. That is the problem with recordings. If you misunderstand the word once when you hear it, when it is said the exact same way again your brain is likely to mishear the word again. at least that seems to happen to me a lot.

[@iycgtptyarvg]

In the end you state that both birds dip at similar rates. That's quite astounding. Are we talking really close, or are we talking order of magnitude close?

[@MrJakewray]

music at 4:45 sounds like jak and daxter precursor legacy

[@ronaldderooij1774]

I want a dipping bird, but here in NL I cannot find them (and I do not want to order online).

[@24KMarii]

So if it can evaporate if I don’t have it at a certain temperature

[@PTNLemay]

Science with Brady!

[@Kreamax]

Very cool video

[@Bbonno]

How about cups with something that evaporates easily? like ethanol, acetone or even dichloromethane?

[@interstellarsurfer]

Did you try cold water for the head, and heat for the tail?

[@regankoopmans8434]

Really great video!

[@leocelente]

Can you imagine if content like this was produced daily?

[@VeteranVandal]

Leonardo Celente It would be quite difficult IF possible.

[@outshimed]

I like the new video style, Brady. Nice haircut too.

[@thesimonien]

I would love to see it in rooms with water saturated air, and dry air! That would definitely confirm the theory. Weren't you scare of seeing the bird explode by pressure when playing with high heat??

[@azurmarlinW]

can you tell us which camera you are using? i know they are expensive but it would be nice to have comparison between price and the output you get :)

[@andyhenrici5807]

Can you try the experiment with liquid nitrogen?

[@sixtysymbols]

+Andrew Scott Henrici like your thinking!

[@pcfreak1992]

I understand him, I would also be cautious of that hot water, don't want to burn myself.

[@Veptis]

You should get germanium glasses to actually see he temperature of the liquid because glass isn't transparent to LWIR

[@paulhiggins4210]

Great video (as usual). P.S is that a moon watch you are wearing?....the moon watch could be a subject for another video :-)

[@niclikescakes]

what thermal camera is this its amazing

[@Dronescaper]

Can time be quantised?

[@ainselyharriot517]

Love it, great video!

[@Prussiaz]

This video was oddly interesting for a video based on the Thermal imaging of Dipping Birds.

[@NGC1433]

This is great! Very interesting! Thanks!

[@guillermoalejandroperezlob5208]

Love to see you doing physics yourself! :).

[@gasdive]

Dichloroethane boils at about 40C. How did that bird not explode with a tea light under it! Neil wears those safety glasses for a reason!

[@moffboffjoe]

What about the tea light + freezing cold water?

[@smith2luke]

Can we generate energy by placing these things outside of other machines that produce much heat?

[@cortster12]

No. Instead, you could use that heat for boiling water and using that steam to turn a turbine. But by then you have how we generate electricity for almost everything.

[@smith2luke]

Power plants generates a ton of heat, which creates a differential in heat, which can power "dipping bird engines". Isn't that possible?

[@cortster12]

Jack Poon Why? When the power plants generating heat is already used for power? That's how they make energy, by generating heat which evaporates water and turns turbines. Dipping birds don't generate energy.

[@smith2luke]

Cortster Here is my analogy (I'm not sure it works 100%). When power plants (or anything that generates waste heat, like the back of your fridge or a Google server farm), it's akin to the hair dryer in this video, which means it can make a dipping bird move back and forth. Some clever engineer may be able to build a dipping bird that, when it moves, it turns a turbine and generates energy, similar to a wind turbine.

[@smith2luke]

I'm not talking about the heat that power plant uses, but the waste heat that it discards.

[@ammelr]

The dipping birds go really fast if you dip their beaks in alcohol (or some other volatile compound) instead of water.

[@26magicman26]

i used to have one of these, it dripped water everywhere >.>

[@Summy_99]

Could you please make a video on string theory?

[@Flir]

love it!

[@mrtnsnp]

What happens if you use ethanol instead of water?

[@samimas4343]

how can someone dislike innocent curious science?

[@samimas4343]

Massimo O'Kissed what does have to do with any thing

[@Triantalex]

Just click the dislike button.

[@mindthesyntax2999]

the HI vinyl in the back ground... jealous

[@chopperboi89]

So how about hair dryer on the bottom, cold water for the top? I'm sure it would drink pretty fast! :)

[@goyabee3200]

You're looking for shattered glass everywhere

[@TheSuperCommentGuy]

I was thinking about this. That flame was awfully close to the glass, and I doubt the glass is made to withstand dramatic temperature changes

[@EadsJasper]

Am I the only one who noticed the reflection @3:38 ? Some one explain this please.

[@jheckman314]

hey, try making the bird drink acetone or isopropyl alcohol. What do you think will happen?

[@PinkChucky15]

Awesome, I've always wanted one of those birds :-)

[@capnthepeafarmer]

Now do emmisivity! Very important when looking at thermal images.

[@nikolayrybkin3265]

1:49 "due to the toy's design the bird becomes top-heavy and tips over" I'm disappointed you didn't explain how toy design makes the toy to take position with the center gravity placed away from the vertical line when all the liquid is in the bottom bulb.

[@guilhermedantas5067]

Amazing!

[@skyr8449]

so, a strangely designed Stirling engine?

[@speckrel4512]

just awesome

[@alecclews]

So where is the paper Dr Haren?

[@Standard37]

My Lord, I need to fix my sleep routine

[@MingoMash]

Poor bird drinking from the ~100C cup, it's so hesitant in the beginning. I bet that after a while its beak was so numb from the heat it didn't even care anymore, and caught up in speed with the ~1C bird.

[@bobfuhr4520]

My bird run 4 hours and 45 minutes without water.

[@cybermbebe]

This is probably a stupid question: if you set 20 dipping birds side in a line, would they synchronise after some time?

[@thenorup]

The birds are not coupled in any way, so you would have to wait a really long time for them to become synchronous for a single dip, but would then fall out of sync again soon after.

[@shantanurahman5084]

I loved it. :)
