Alex, you have great enunciation. And just the right amount of movement, neither still as a statue nor spazzy. Knowing that your already good video skills will only get better earned you a subscription.
I promise you are a life saver!!!! I take Biology online and I'm not your typical science major. This video is a great breakdown of the process for my next lab. Thanks a bunch!!
+Amber Walker So glad I could help :)
or should u say leaf saver..
This video is amazing!
I used Momordica charantia (bitter melon), Moringa oleifera (horseradish), and Psidium guajava (guava) and was astounded with the result of my experiment in paper chromatography. I watched your video and followed it closely and it helped me a lot throughout the process. With the help of your video, I witnessed how great science is when understood. I am still amazed at the partition where the solvent seeps along the paper carrying the substances from the mixture to the one end of the filter and the pigments were separated; the result was even impressive after it dried.
Students like me are truly grateful for your amazing video. Thank you, Dr Dainis, I am looking forward to learning more about Science with you!
I have used the common leaves found near my house, it includes: Water Spinach (Kangkong), Oregano, and Malabar Spinach (Alugbatti). With the help of the video of yours, I followed the steps of this method, Chromatography, and I had observed that the molecules have different polarities interacted with the coffee filters differently, layer by layer.Thank you for sharing your knowledge, Dr. Dainis, I enjoyed doing it so!
Who is watching this for science class?
David Peters I am also watching for my science class
wow cool man
David Peters meh ....😊😁
you suck.
big shlong.
You are awesome. Good to see that I'm not the only dork who finds all this stuff fascinating. Subscribed.
I used oregano, chinese evergreens, and devils ivy. And the result was great the color of the isoprophyl inside the glass with some leaf really changed, and the paper changed color a bit but it was really amazing. Thanks for the info Doc. I've learned a lot.💙
OMG THIS IS SUCH A LIFESAVER AND VERY EASY TO UNDERSTAND THANKS!
I don't mind losing to science. But yes I find your videos awesome. Can't wait to watch future ones.
A suggestion for keeping the filter paper from touching the side is to lay a pen or pencil across the top of the bowl/glass and then tape the filter paper perpendicularly down from there. It has worked well for me in the past with ink chromatography.
you're wrong you idiot
I got here from the numberphiles video. I'm definitely going to subscribe. I love videos that teach you things. And plus, your smile is so very charming.
Thanks for showing us this channel.
Hey! New subscriber, medicinal chemist from Australia. This is probably getting old to you now but you are amazing! Keep it up!
This is because the isopropyl alcohol pulls the water out of the leaves through the porous membranes of the leaves by osmosis, right? And as the water is drawn out of the leaves it pulls the compounds with it, and the compounds like chlorophyll and carotenoids are drawn up the filter paper by diffusive capillary force, right?
Hi, I'm from Indonesia, glad to see that you are full of enthusiasm in providing the knowledge you have, sis, may I ask, how to treat living plants so that their color changes from green to partially white, and permanently, what should I do, thank you sis for the time . GBU
Hello,What is the advantages of doing this?Because i need to answer with the asker when i do it.
Is there a way to the separate the alcohol and the chlorophyll so it would leave a powder or paste?
and also can any alchole be used for this experiment or is it only the type you stated?
what can I use instead of isopropyl alcohol ?
Do you know what we are measuring in the project
Your are a life saver for my science assignment 😊😊
What type of leaves did you use?
Chlorophyll is more polar than the carotenoids, so it sticks to the paper a bit more. This means the carotenoids are drawn up by the liquid faster and appear above the chlorophyll.
Nice, that's a really cool experiment!
Awesome experiment instructional! Also more informative than nottinghamscience's "Why do leaves change colour?" from the other day. I'll try the experiment just as soon as there aren't 60mph winds outside.
Good little teacher, like that style of course
i wanna see what happens if i use blood to water my plants and then do a chromatography on em.
they would probably die right?
You're right Alex. Xanthophylls are part of the carotenoid group. Leaves normally contain both xanthopylls and carotenes and as for which one dominates depends on the type of plant. Spinach leaves for example are famous for their high lutein (a xanthophyll) content because they have significantly more lutein than beta-carotene.
I have to do some assignments from home ( because of Corona ) you are a lifesaver!!
I'm stoked that NurdRage sent me in the direction of this channel. I love me some science videos!
Great video! I remember we did chromatography with blue ink in school, the result was some colorful paintings in the paper :P I will try to do this at home :)
Great stuff!
what is the purpose of this experiment?
Very nice experiment of science l know many things about the leaves
love these videos :)
I used Oregano, parsley, and mint. As I observed it separate substances based on their color as was the case with herbal pigments.
OMGGGGGGG this was so good my class liked it
but what if im doing on how they get old
great video!
Made on my B day!!! I love how you explain all this science in a fun way!
how much alcohol did you use?
OMG you saved my life, without this video my project would have been a straight 0.
Thanks for the info; my science teacher assigned us a project on pigments and the like. Again, thanks much.
Your accent is so unique!
Can we use normal alcohol instead of this
Vry nice video ..... Helped me a lot one day bfore my experiment ....
great video!!!! i wonder what will happened if i change isopropyl alcohol with hand sanitizer.
Question: I'm doing this for a science fair project but how am I supposed to arrange my data?
why do you use alcohol instead of water? Please answer this my lab is due tomorrow LOL
1:42 that is one awesome theory, I love it :D
Thanks! I was so excited to be in that video with so many awesome, amazing TH-camrs! Hope you stick around and learn something :)
Omg.. That was magic, one minute she didn't have her glasses on and the next minute the glasses reappeared, I'm impressed..
Gosh I started watching UR vids at 9 and I looked at the clock and know its 10.
great video! i am going to do it for my science fair with my friend! i recommend you do a video on sodium alginate balls in photosynthesis, it is a very interesting experiment and that will get many subscribers!
Thanks! I keep trying to make each one better than the last, so I hope you continue to enjoy them!
You are fantastic!😀
Why can’t the filter paper touch the glass?
Wow. Pretty cool, I must say. Another subscriber, count me in!
Thank you! I have to do investigative project on determining if callaloo pigments are all the same and this video gave me some really nice tips on how to carry out this experiment and understand the topic.
Thank you so MUCH! :D
It's actually just "I Love You" in American Sign Language. Just trying to spread some love!
thanks for movie helps alot in my study, really interesting...
If the leaf is colored, it has pigments and they can be separated. Now if the leaves are all brown the pigments have probably broken down already, but if you live in an area where the leaves don't change color, they still have pigments and can still be separated.
i want to do that in grad school too! What's a good one for it? I'm looking at MIT but I might need to look elsewhere.
is this a photosynthesis expiriment?
@Alex Dainis Did it blind her?
Wow, I admire you!! I have a question I'd like to ask. I'm doing a science fair project based on this experiment so it's the beginning of January already. Luckily, I have got some leaves from before hand but I only have two colors of the same bush and another color from another bush. Should I just use the leaves from the same bush or use the extra leaves from the other bush too? And would you mind giving me any advice for my project? Thank you, and greetings from California! (PS I have watched this vid about 5 times)
I think it would be interesting to try all of the leaves! That way you could compare both the same bush at different times and a different kind of plant. The more kinds of leaves you use, the more interesting things you might find!
I have in fact been keeping up with your videos, and they have all been very interesting. Your presentation is awesome, and you pick some really good topics. I even go around and tell all of my friends about some of the stuff in your videos. You have so much interesting information.
Can you do a Bit Scized on the effects of alcohol on the body? And how exactly does alcohol poisoning work?
Yeah, it gets a little echoey at times... I'll work on it!
OOO LOZER
Pretty cool
hi. i am a korean student. i was impressed by your experiment. i want to capture this video and use it in science club. and i want to put the course in the club cafe by using this picture. i will reveal the source. can i use your video?
I owe him a bag full of nickels, I feel so honored to be in that video with so many cool people! I'm glad you like it!
Where you live
Strictly speaking this is not paper chromatography. The solution in the beaker is just the solvent, not the mobile phase of chromatography. The trick is to choose a mobile phase which separates the different components of the mixture.
Such a clear explanation and simple experiment, thank you. I plan to use this in my Kindergarten!
Neat! Subscribed. Thanks.
like your enthusiasm girl;) good work;)
Idea for another video? Anthocyanins are not actually always red(I know you know), its colours depends on pH of surrounding. Another pretty experiments can be done with them. You can use chromatography to isolate them and then make solutions with different pH, few drops of anthocyanine solution and magic!
if i do this experiment, which questions can (Maybe) they ask me? :)
Yeah, we´ve made that experiment very recently. Tip for cooking enthusiasts : try to add some sodium hydroxide to your red cabbage next you are cooking(no, don´t actually do that...) What are you studying, biochemistry?mol. biology? Super-duper videos btw :) and sorry for eng, i´am trying...
Hi I found this link from NurdRage, Like what you are doing here.
P.S.
I like the glasses quick change/continuity thing.
my science teacher sent me this link, and we did the experiment in class
I always wonder how people are doing several years after their comment. How have you been? Are you still in school? Do you have a job? Are you still alive?
nice one
That is a good point.
Target alcohol! Up and Up products go on sale across the board during the fall months.
thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!
we are starting spring, so we may not get many different results from the leaves
"the leaves are being seperated from alcohol phase, the mobile phase and Drawn up into the paper, which is the stationary phase."
Is this where we get the name"stationary" for paper and paper supplies?
I cannot believe how much content you got into 4 minutes and 24 seconds. Does the mass of a video increase if you put more content into it?
So well explained - thanks! :D
Nurd has sci-cred, so if he says you do too, then how can I resist! Enjoyin the vids \m/_
You're so cool.
I love epigenetics (It's what I want to study in grad school) but there's so much and I think it's so important that I want to make sure I do it right. I will definitely make a video (or two, or four...) on it, I just don't know when/how yet!
That was awesome i tried had home
Great initiative, its nice to see someone who simplifies experiments so that kids can try these at home. It would be even better if you slowed down your talking a bit, its hard to follow with your hand movements and fast talking. If you had less liquid in the cup the separation would have been easier.
We all want a Featuring of Nurd Rage and Alex Dainis ! The Couple scientist ! Ahah ^^
Thank you!! You are so smart. I'm doing this for a science fair experiment and this really helped me understand all my research better!]
really wow
sooo smart
That's my science project
That is a fantastic suggestion, and one I hope people see!
