"Don't drink everything in this video" Sooo, if i drink a BIT im fine?
you can drink tonic water...uhh don't do too much oil...and you don't want to drink the chlorophyll solution.
Should have said anything
But what if I want chlorophyll in my body so when I go outside I can use that chlorophyll to make energy for myself
You need to be a plant to make use of chlorophyll. Your body is not made for photosynthesis.
@@redstonedragongaming8795 Well technically photosynthesis isn't limited to plants. There's a species of slug (I think they're native to California?) that is capable of photosynthesis. Sooo. Yeah.
Your videos are always so well produced and voiced over. Thank you for taking so much time making them so nice!
seems like you are an experienced magician, you make us think that you use sience when actually you use magic
JoraForever
Well, magic is just science beyond our comprehension in my opinion.
Hence it is called magic, much how like if a women did something slightly strange in the middle ages she was accused of magic and burned alive.
that is so obvious :D
JoraForever
Yes, lol
JoraForever yes but how long until he notices that he spelt science wrong
magic? na a not magic, is superpowa!!
Well I bombed on my guess. It is always a treat to watch your material as it educates without going over the top with very technical descriptions of 'why'. All the best and I look forward to the next one. Cheers.
The traffic light idea was a really awesome idea! I also really liked how the colors of the liquids go really well with the laser light colors. This would be a great idea for a lamp or decoration
What, no Pokemon tears and dragons blood? Damn I thought I had it!
Thanks for considering me as a viewer of this channel. I've been there since 30k,and even the older videos fascinate me. Good work!
Thanks for being an active viewer and positive commenter! More videos to come :)
Nice one, Keep the experiments going.
YAY! a rare brainiac video! just what I needed today! thanks!
Rare but always worth the wait :D
I really enjoy Brainiac for his exculusive way of mixing science and art. Not everyone can achieve such a cohesion between those two fields and still offer a content that is suitable for large audience. All of this and he still asks us to put a like "if" we actually liked. Keep the good work bro! keep it up!
Finally a new video :D
Simply beautiful. This has to be a form of art somewhen...
Another good video? Ahhhh man, what're you doing to us!? Magicians always amusing the audience with SCIENCE!
Ahhh yes new upload! Just what I needed :)
Nice Dutch flag you made. :)
#TeamDutch
it's more like🇫🇷
Also, use UV eye protection when working around UV lights. Having to get cataract surgery at an early age isn't fun.
Ah damn it, I was so close! I actually made one with olive oil - sunflower oil - tonic and it looked almost identical :P
anyway, awesome work, can't believe that your channel has grown by over 2000% since I have found you! :O
Olive oil would work for the red top layer - but only shortly I guess since the olive oil and sunflower oil would like to mix :) Thanks for the support!
/braniac puts weird colorful powder into beakers/
Me, an English major: Now THAT is science!
Netherlands, Luxemburg and France particularly love that Video
Beautiful video!
Thanks for the mention! Love your videos. It was hard to tell what sort of oil it was, I was hoping the paper would score me brownie points haha. Nice to know my colour mixing hypothesis was right!
Great work!
Beautiful!
that is really cool :) what i also like is the fact you used different wavelengths to make different patterns with the laser pointer.....anyways thanks for showing us more cool things, i am glad i subscribed to your channel keep up the great work
i always get so happy when i see a video of you :)
you outdid yourself this video my man
8:14 I was amazed like a little child seeing this. It looked like some kind of felfire potion.
Fluorescein really is amazing. May even be better in real life. The fluorescence is so visible and bright almost no matter what light source is used. Thanks for watching!
I first watched your channel with the monster magnet meets computer video and subscribed. I still don't regret that decision
I watched every single of your videos at least once and always get extremely happy when you make a new one. This is the only channel for which I have notifications on and like every video before I finish watching it. Thank you for sharing your passion with us. Also those annotations with the extra info are awesome! In addition, from most of the videos I get a new way to surprise my girlfriend :) Like magically awakening moss in our garden :)
Hehe, thanks for the support! I believe I have found my style and place here on RUclips with the audience for it. Thanks for being here - more to come!
This is awesome!
Nice one, Keep the magic flowing. Sorcerer Supreme Practitioner of the mystical arts.
That was another excellent video Brain. :)
Sweet! I was wondering when this was coming out!
you amaze me mate !!!!
Your container of Rhodamine shows the same effect as mine: no matter what you try, you get red stains everywhere! ;)
And yeah, the amount you used was a little bit much ;) . I used not much more than that to color water outside during a few days of heavy rain here in Austria, when it was so wet that we had water ingress in the basement (came in at a rate of a bucket every 5 minutes). I had two suspect places outside where the water could come from, so I used Fluoresceine and Rhodamine. Three hours later the water coming in was sligtly red. The teaspoon full of dye must have been diluted in a few thousand liters of water and still the water was slightly red. In our case that meant we needed a new drywell, because that was the culprit (clogged up after decades and instead of seeping away deeper into the ground it was seeping towards the house, where it must have washed out small underground "waterways").
Yep, rhodamine is an incredible efficient dye. Makes it very useful for tracing leaks though fluorescin is often used because of the bright color (and being less dangerous in drinking water...). But a smart solution with the two different colors when faced with two possible sources!
Bravo!
i was waiting for a lot of time for this......thanks :-)
I love your videos!
Thank you so much to make this video :)
I make sure to watch your new videos first before I even consider any other RUclips video
That's amazing!
Thats the way to make science cool and fun keep upload more
Thanks, hope to release a new video at the end of this month. Much more to come :)
Another amazing video! What a nice Dutch flag you made there!
Hm I never would have guessed sunflower oil. Fluorescence is such an interesting property! that orange-red dye at the end of the video was very beautiful
Yep, fluorescence is not as rare as we might think. Phosphorescence is though. Fluorescein is indeed fantastic. Such a bright fluorescence and very easy to excite. Thanks for watching!
Brainiac75 do you plan on doing videos about phosphorescence? I'm assuming materials that exhibit this are quite expensive :/
There are some commonly used phosphorescent materials that are made on a large scale. They aren't that expensive. I have a video about phosphorescence here: ruclips.net/video/is1VH1yht2w/видео.html
I would definitely stuff for that stop light :-D
great video I learned a lot
Mannnn your videos are amazing!!! Just when I was wondering: hmm but what laserpen did he use, you were starting to explain exactly that :D
aah - Cute, That Traffic Light has been playing musical chairs.
your videos are so... aesthetic
Very Nice video
I love your videos
I didn't know that white light would come out some formerly absent color when shined through certain fluids. Surprising.
Blue, white, red(red, white, blue - whatever)... you chose the right day to post this. No idea, if that was your intention, but well done :)
Well, if you're thinking about a flag this color combination is found in a lot of countries flags. I wasn't aiming for a particular one :)
nice video!
If bioefthanol wasn't flamamble than I would make a lamp from this :)
(By the way I really like the fact that You read yours viewers comments)
I have worked with lasers for a long time now and never thought of doimg that with those compounds! Excellent and absolutely beautiful piano track. My 405 nm laser will work great. For the record, a 450 nm laser will overpower this so much it takes away from the beauty if it (granyed my 450 nm laser is a 1,000 me or 1 watt version so that doesnt count really).
4:00 All hail France!
hey brainiac, you should make a blacklight lavalamp, where all the layers are transparent but glow different color above the blacklight. i think that could look really cool
I think the third laser is labeled < 5mw to avoid the import restrictions in many countries.
That's a cool lizard
Red White Blue, the Dutch flag xD
and the UK, US, Russia, France...
Or luxembourgish
Yes, but this is in the right order.
AND DON'T FUCKN FORGET ABOUT GODDAMNED AMERICA
Tribute to France's dead POIs
Water - You float too Oil YOU FLOAT TOO! U FLOAT TOO!!!
Nice to know. :)
Ohhh man!!! I thought it was dutch patriotic blood form the tulip fields cultivators!!! What a bummer!!
got to try this myself
Well wait, but what happens when you cap the cylinder and then shake it up? What color would it be? Some kind of light purple?
Haven't tried it. I guess it would be mostly a white fluorescence - maybe with a purple tint.
Oil isn't going to mix, but the chlorophyll extract and the tonic water might. Still would be interesting to see tho
Yay, I may not have been first but had them correct! 👍
The one I guessed is... Semechki oil. (Sunflower seed oil)
Just because I know that something in top of a liquid that is a liquid is something less denser.
good video
The year is 20017, Brainiac has made another video. I just need to see it and I can die happily.
Super
basic phisics :) still a great video, keep it going !
Quinine is my favorite.
A lava lamp would be awesome with this concept.
"Captain America's tears" lol what a comment
You have beautiful windows
Maybe try a UV ccfl? I'll be trying once I go to the store and grab some tonic water and sunflower oil. The ccfl use to be cheap as there was a bunch of old stock used as PC case lighting until LEDs became popular.
Wonder what it would look like if the fluids were slowly stirred? Vortex perhaps?
Also, if the container was sealed, how long would the fluids stay stable (particularly the bioefthanol )?
Does the laser color have an effect? So, for example, to do the cylinder flag, since chlorophyll fluoresces in UV, do I specifically need to use a UV (or close to it, blue) laser, or can I use green or violet? Are
Loved it, even tho my comment wasn't chosen, WHO cares?? I still luv yer channel. :) god luck!
Vive la Revolution, French flag was amazing
Red white blue I like the collors
Interesting stuff! I do have one question about lasers in general though: Why do laser beams have a sparkling look to it when it is reflected back at you? I really am curious about that!
The sparks are due to dust, insects etc. in the air reflecting the beam. The laser beam is very bright, so when even a small particle in the air reflects it, you see a bright flash from the reflection.
Oh, that's cool! Thanks for replying! :D
9:02 what would happen when you take cold water and warm up the powder(?), would it then sink slower to the bottom (or vice versa)?
Annuda day, annuda Brainiac video
-M. L. King
Why isn't the color filtered out when the laser passes through each layer? It seems to remain consistent if the laser passes through other layers or is passed directly from the side. I'd expect that if shown through the top red layer then only that color would pass through to the next layer.
the color is filtered out, but when the laser hits each substance it absorbs the light and fluoresces as a different color. like how a uv light shines on something and the fluorescent material shines yellow/green even though thats not the color of light entering
The layers only absorb a small amount of the laser radiation (the liquids are mostly transparent after all). There's still enough of the "original" light for the other layers. The fluorescent color is also emitted in all directions, not just the beam direction (obviously you wouldn't be able to see it if it were).
the 3 liquid colors is red, white & blue in my eye. it's the Netherlands flag & the biggest laser in this video can burn a paper if you aim it longer.
FRANCE!!!!!
I bought a green laser pointer from newegg, it was also mislabeled, "
I would really like to buy a genuine laser power meter. With the flood of Chinese unbranded lasers on the market it's really difficult to know the real power of the lasers. Laser power meters are just so expensive...
Where do you get Ajax spray cleaner with English labels in Denmark?
Odd, I had assumed you were German, although your accept is pretty Danish now that I think about it.
Dav :)
I greatly enjoy your videos Brainiac. But I really want to know the name of the music around 4:15. With brotherly love from Russia!))
Thanks :) Full music credits are in the description box under the video. Greetings back from Denmark!
oh! Thank you)
Den der "ekstra jomfru oliven olie" kan du godt proppe skråt op!
Hehe, endnu en fed video. Jeg subber ☺️
Haha ja man kan ikke lave mad med "ekstra jomfru oliven olie"
Tja, skal ikke bruge så meget madolie i min hverdag, så jeg købte de billigste, jeg kunne finde til videoen :) Vil prøve at bruge olierne til noget andet i en kommende video. Velkommen som abonnent :)
He didn't stress enough: Lasers above 1mW are dangerous and can damage your eyes! The damage may not be perceivable but it degrades your eyesight. Think of it as dead pixels in an LCD screen. They don't prevent usage of the screen but do reduce resolution.
where did you buy that laser???
keep up the good work. :)
it looks like the dutch flag when you light it up from the top
I believe I bought it on sale from dealextreme many years ago. Can't really remember it :/
thanks
7:54 you shouldve shaken the cylinder converting3 to 2 layers and chaning the color of one
would be a nice magic trick
2/3 I'll take it
French drink! ;)
Put fire to oil and throw it : you got magic.
Could you explain how to calculate a laser array?
FINALLY
So... I wonder...
Where does one "glow" from here...
