Forget the colors. How did you use those crystals to travel back in time to the 1970's and acquire that combination of mustache, hair, and clothes?
RETRO styling is coming back, apparently. It's a shame...
I think he's preparing to retire in Florida
He did a video on time crystals, just fyi. 👌

Wait, that’s illegal! :D
xD
2:10 that diagram looks interesting. Might make for a good album cover
Lol
Lol
Such a shame that probably only older people got that.

This channel is a treasure for science students. Amazing experiment carried out by this gentle man. Thank you so much. ❣️
I love science! Dude, you're awesome, by the definition of leaving me in awe, for all that you have posted. Keep up the good and smart work, thanks for all of it.
You're starting to look more and more like my science teacher all that shirt needs is some pink flamingos and you'll be set
He has two possible career paths now. Science guy, or history teacher.

Sto making comments like these. Not everyone likes The Action Lab.
@@jinkaleb7414 whyy??? Do everyone likes just politics like riots and diplomaceas? U should like science and thus, the actionlab
@@jinkaleb7414 may be u failed in science
Dude you are truly an inspirational person, thanks for the videos and the things you ask and answer in them.
At 1:58 , didn't realise I was listening to Dark Side of The Moon album...
I've always wondered how colour changing necklaces are made....

Dude, it was your mood.
lol
I absolutely love your videos!!! And 👍👍 on the moustache and hair!!😁😎😉
You explain science very well, love them!
Wow! That's really cool! I learned some things from this video that I didn't know before. 👍😀
Not watched this yet... just excited 😆... I love the action lab. Here we go
Awesome Work...
Liquid crystals are a bit more complex. They are molecules that stack, but with a slight angle between each, so they twist like a spiral staircase. When the period of the staircase matches that of a certain frequency of light, that light can pass through the liquid crystal while other frequencies run into the molecule and are absorbed/scattered.
Interesting shizzle...... thanks man 👍
thanks for the knowledge
4:50 damn, that great 'stache is no more
It was a clip from a video he posted before he grew the stache.
wow how fun and awesome is that!
Wow, that is so cool!!

Thanks for this lesson mate.. I've always wondered how the heat-sink on a PC CPU works.
the best channel on RUclips.
Not the teacher we deserve but the teacher we needed
I hope you keep the creepy goofy stash. I love your videos and that is a pretty rare look these days. I hope it is your branding. Alway improving my friend, thank you for all you do!
Boom! Good times “that’s so coooool” ! Catch phrase, tash, awesome !
Man that Nike shirt is a real piece of work!
I knew heat pipes were efficient, but wow that's quick!! I thought it was moving heat in a matter of seconds, it's really more like tenths of seconds. 😳
Thanks God Covid19, you've brought us the best 'stache of 2020
So interesting!
That was the coolest thing I've seen this morning; and I've been up for at least an hour! ps, don't make videos with that Nike shirt again, James - please please. Thanks!
He just woke up in the morning and made this video.
the way the liquid crystals explode at 6:27, is just WOW
Rayaan Khan ?
I see what you did there 😏
@@junkjingle5190 you just got baited into watching to the end of the video 😉
What an amazing vedio this is the reason wahy smartphones have liquid cooling pipe instead of cooling slab.
*Who else noticed the smooth transformation of his hair and mustache in this video.* _1:20__, __4:45__, __6:12_
*If you are wondering how, he just used one of his older video to explain **_how hit pipe works._*
Cool and ur soo close to 3m 😃
Love the reuse use of the older vid in it (wont say cuz subs prolly know what part)
Wonderful
I'm really feeling the push broom mustache.
You teach me more than my online classes

Shinzo wo sasageyo
It hurts to know that people lost interest in him😔...ill be there with you pal😢
Could you use ordinary plumbing materials to make a heat pipe that would keep a cup of coffee warm by transferring heat from a burning candle?
Nice look, Smartsky, P.I!
I wanna paint my whole house with that stuff :)
I have learned more physics by watching your videos than that I have learned in my school 🙏
Whoa, fro! I hadn't seen him in awhile!
Could you make like a copper pot/pan out of heat pipe? And make like a pot that like boils even faster then normal copper??
Wearing a face mask and safety glasses you can get this color changing effect as well from hot breath steaming up the glasses. Looking at light through the condensate you can see a rainbow of colors depending on the thickness of fog.
Bro u say so much scientific stuff that my brain can't process but it very interesting to see
If I understand your explanation correctly, then holding the pipe vertically should change how fast the heat transfers. Heating the bottom should transfer the heat faster since the condensed water will fall down. Heating the top will result in the condensed water pooling in the bottom. Please try this out and see if I am right. Thanks.
I have heard that heat pipes contain liquid ammonia, although i couldn't belive this as it would require immense pressure. Do you know any use of liquid ammonia in heat pipes e.g. industrial ones?
I wish he would put links to all of the things he uses in his videos so we could try this stuff for ourselves. Where did he get that heat pipe from?
Love the tash it suits u
how does the water get back to the hot side in the heat pipe? or does it only work really fast for the first few seconds then starts acting like regular copper?
What's the heat limit for a heat pipe before it loses it's extra thermal reactivity, copper's melting point?
Can you Flash any light into a paper dyed with the blackest material and see from the other side?
Metals glow from red to orange to yellow to, eventually white, and then into the ultraviolet by the exvitation levels of their electrons in their shells. Each time an electron falls one energy level it emits a discreet wavelength of electromagnetic energy causing the colors we see. The thickness of oxidation layers on certain metals causing different reflective colors is a related but different phenomenon.
Does anyone know the bandwidth range of the color shift here? How far into the Infrared and ultraviolet range? This could be useful for spectrography with the right light source and and photodiode
I have a question regarding why heat pipe conducts heat faster? In conduction mechanism in copper, when you pass heat the molecule in one end vibrates which then excites molecule close to it and thus heat reaches other end. While here in heat pipe basically convection is happening. So does this mean convection is faster than conduction?
*_Came for the video, stayed for the tache!_*
Nice look! I had no clue you were a 70's adult film star. Was film #1 the "Action"🎬 Lab"?
???
Wtf bro skskks
What is more complicated
Like: action labs
Comment: Mumbo jumbo

Makes me feel old to know this guy has never seen a mood ring or a hypercolor t-shirt...
Oh snap, hyper color shirts for sure.
I kinda remember those shirts when I was like 5
I'm only 15 and I remember mood rings. Never heard of hypercolor shirts though.
I've seen them on TV. Should I get one?
I have first seen a mood ring when I was like 5-7 maybe
Diamond sheets should actually conduct heat faster than a heatpipe. You should get some for experiments.
Cutting ice by conducting heat from your hands is way more effective for instance.
How does the water vapor in the heat tube not oxidize the copper "sponge/wick)?
Does the starting temperature of the water effect the speed of transfer?
Ooooo so that's how colour changing Hotwheels are made😂
The mustache looks sick.....
Love the new look
Go to 4:50
he needs a haircut ffs, it looks so messy
@@girlsdrinkfeck lol
nice shirt dude
As soon as he said there is vivid colors now, my night mode turned on and the colors got even more vivid, or I guess red shifted.
Does the heat pipe work the same when the water inside freezes?
Me: reading chemistry textbook chapter 'liquid crystal'
RUclips: action lab has uploaded a video 'liquid crystal'
Illuminati 🤯🤣
Could that be because he is involved in some kind of school stuff that uses the same content schedule as your schooling? Maybe that's partly how he decides to do videos?
So since this heat pipe transfers heat really fast wouldn't it also do the same with electricity? I think that the amount that heat transfers and the amount that electricity transfers are somewhat proportional. Right?
Nice stache
I learned all this at the exploratorium in San Francisco
Holy crap! With that ‘stache, you look just like my Grandpa when he was in his 30’s!

I have few chickens 🐓 and recently I noticed that they gets heavier when they die,why that happens?
Thoughty2 called, he wants his mustache back
5:15 but in this picture , there is two pipe inside one but not in reality as you shown open pipe ?
Bragg would be really proud of you
would it be possible to put some sort of micro turbine in the vapor path?
4:28 Cant tell if thats just a sheet of paper colored with thermochromic paint or is it something else?
Exactly which paint from the color dust site is being used ?
@4.30 what a material was used to show a heat conduction.
Please run a current through the heat pipe and liquid crystals.
HELLO SIR CAN YOU EXPLIAN THAT WHEN WE PUT LOTS OF SMALL PIN IN THE NORMAL DRINKING WATER GLASS TO THE EXTREME THE WATER DOESN'T SPIL OUT WHY SIR PLS EXPLAIN AND VERY QURIOUS
nice stach
not water, unless you're designing the heat pipe for temperatures above 100C. For most applications you'd use something with a much higher vapor pressure, like acetone.
Mood Rings Mood Sticks!!👍👍
Nice
nobody:
The action lab: LIQUID CRYSTAL
Is this the same thing that is used on aquariums to show water temperature?
Mihai Balint probably not although it may be something similar. There are many compounds that are thermochromic which means they chance their color in response to temperature. Aquarium temperature gauges likely don’t use liquid crystals but probably some other compound that does the same thing
Cool huh!
So why aren't all materials like this?
Isn’t this what they use to make mood rings?
what if u apply electricity to it ?
I would like to see the Liquid Crystals on the heat pipe under a black light.
