The default temperature scales are based on surface emissivity of 0.95... Temperatures we've added to images are also approximate but adjusted for varying emissivity.

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.

[@AdibasWakfu]

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

[@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!

[@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

[@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]

[@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!

[@Simp_Zone]

Geez you stoopids need to bone up on your classic simpsons

[@Candoran2]

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

[@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.

[@samimas4343]

how can someone dislike innocent curious science?

[@samimas4343]

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

[@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.

[@AlfieM360]

I liked this slightly different style :)

[@AlexKnauth]

[@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.

[@Nurr0]

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

[@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...

[@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. :-)

[@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!

[@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.

[@davidmurphy563]

simontay1984 Tried and tested Victorian tech - was famously used to power foundries in Scotland. Obviously has its pros and (many) cons and isn't a replacement to internal combustion but its efficiency very high and it's been used in submarines very effectively where it gives advantages of low noise and is suitable to the environment.

[@BrunoWeiers]

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

[@munkeyz]

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

[@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.

[@DEFarnes]

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

[@AlexKnauth]

This makes it much clearer, thanks for the video!

[@TheHorseHat]

This is a really great video, Brady.

[@MozartJunior22]

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

[@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!

[@palmerjwm]

Great video Brady!

[@tgijc]

Great video, tks Brady!

[@PetrFlosman]

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

[@leocelente]

That was seriously awesome!

[@scottramsay3671]

I love this slightly different format of video

[@ollenmt1729]

Great video Brady! :D

[@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.

[@Felipehez]

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

[@Modenut]

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

[@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!

[@vasilistoxo]

Really nice, well done.

[@313Hades]

"I just tripled my productivity"

[@regankoopmans8434]

Really great video!

[@karlmuster263]

That last one was pretty cool.

[@ainselyharriot517]

Love it, great video!

[@artswri]

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

[@Kreamax]

Very cool video

[@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 :)

[@Cruuzie]

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

[@MarkGarth]

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

[@guilhermedantas5067]

Amazing!

[@pcfreak1992]

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

[@Standard37]

My Lord, I need to fix my sleep routine

[@NGC1433]

This is great! Very interesting! Thanks!

[@speckrel4512]

just awesome

[@leocelente]

Can you imagine if content like this was produced daily?

[@VeteranVandal]

Leonardo Celente It would be quite difficult IF possible.

[@Flir]

love it!

[@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!

[@PTNLemay]

Science with Brady!

[@PinkChucky15]

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

[@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

[@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??

[@shantanurahman5084]

I loved it. :)

[@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 :)

[@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 :-)

[@IllidanS4]

Nice!

[@niclikescakes]

what thermal camera is this its amazing

[@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?

[@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?

[@guillermoalejandroperezlob5208]

Love to see you doing physics yourself! :).

[@001100AAAEA]

Very cool

[@001100AAAEA]

Very very very cool

[@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?

[@Prussiaz]

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

[@LickMyGlass]

I've been wanting to make something cool out of glass with this design, something more than a drinking bird... any ideas?

[@andyhenrici5807]

Can you try the experiment with liquid nitrogen?

[@sixtysymbols]

+Andrew Scott Henrici like your thinking!

[@outshimed]

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

[@Gooberslot]

What would happen if you super cooled the head?

[@Mastikator]

You mean like have a glass with liquid nitrogen?

[@hunterdouglas9765]

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

[@ronaldderooij1774]

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

[@mindthesyntax2999]

the HI vinyl in the back ground... jealous

[@austinchin3846]

Heheheh Brady showing equations thats unusual

[@highnet8717]

youtube unsubscribed me from this channel

[@sixtysymbols]

I hope you re-subscribed!?

[@robinschepenburg8282]

Joaquin Telleria rly? then pewdiepie is telling the truth, stupid KZbin

[@terrafirma9328]

Has anyone thought to scale this up to generate usable power?

[@17ksAlt]

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

[@interstellarsurfer]

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

[@Summy_99]

Could you please make a video on string theory?

[@Bbonno]

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

[@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.

[@scienceandmusicmix]

watching this video with one of these dipping away on my desk :)

[@sayanmondal4570]

great

[@Veptis]

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

[@26magicman26]

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

[@lordoftheflings]

Darkman nods in approval

[@jheckman314]

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

[@chopperboi89]

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

[@capnthepeafarmer]

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

[@Dronescaper]

Can time be quantised?

[@sirkowski]

hehehe! It's going back for more.

[@Hobbychemiefreak]

Would've been also great to see this tested with solvents with completely different boiling points than water. With diethylether the bird would probably be dipping every few seconds I guess...

[@ammelr]

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

[@amir-ali8850]

Tnx
