I legit waited until the last day to start my lab report so now I’m watching as many of these videos to come up with a convincing report😂
same
Sameeee😭
Sameeee!! I hope my teacher doesn't find out!😂
Me right now..
me to 😭😭😭😭
Oh me trying to do a lab that takes a whole week in one night 🙂
u tryna send awnsers
i only have 25 mins left
Right 😭
hahahaha this is so true
did you success do it in one night?
POV: Your biology teacher showed you this video to explain Osmosis
Lol I am doing this
Me too
same lol
Same 😝😝
Anyone have Mr. Glass?
I learn more through the internet then at school
*than
Tru
@@dawnkelly3614 YA THAN
I learned this at school 😂
Sury The Cat this is so true i swear
These guys just saved my lazy ass from actually doing the experiment. THANK YOU 🙌🥺
yea same
same 😂
i still need measurements for everything sadly, idk what ima do
@@atulmarichetty1773 bro slide them
hey is it a hard boiled egg?
This is an experiment from my modules in General Biology and had no time to make it. Glad I found this in your channel! Thank you guys.
My egg “died” in the colored water so I was screwed. I needed this XD
How does egg simply die
@@loyener8607 It simply dies. That's how.
@@deathfromthedepths bruh
Mine too, it somehow expoded but remained intact. Had to start over...
welcome class of 2024, to your biology class.
Actually I'm class of 2026, but same difference
Shut up

Class of 2026 here but it doesn’t matter
There's a couple of important phenomena you guys left out of the last 2 graphics.
1. During the corn syrup stage: Once the water exited the egg the surrounding corn syrup became less dense, and rose towards the top of the glass. This means the water concentration outside the egg stayed [reasonably] constant (the graphic depicts a saturation outside of the egg).
2. Dye stage: There aren't any pigment/dye molecules depicted entering the egg (or even staining the membrane which I suspect attributes to most of the tinting.
Also, this is mostly just a nitpick, but even before an equilibrium has been reached there's still a cross exchange. In other words, some water would be exiting the membrane while a larger portion was entering. Your graphic omitted this, which is actually good for keeping things relatively simple and easy to learn. That's the way professional graphics depict almost any molecular phenomena. It always gets to me when I see that though. In my opinion, the more realistic the dynamics are the better the educational value. You can still make things clear/simple by hilighting, or isolating, a demonstration area (center of the screen) while having a more realistic fluid dynamic in the background/edge of the screen. Possibly even in the actual background, if you want to include distance and a 3-dimensional view to the cross section display (like looking into a microscope, you tend to have space for a few layers of cells).
Lastly if you didn't die from my wall of text... What do you guys think about replacing the corn syrup with oobleck? Would it work?
I think it would, but the corn starch might settle/separate and harden. Maybe adding a surfactant like soap would prevent that, but if that's necessary how would it affect the egg?

SHUT UP NERD!
This website helped me with my science fair project so im definitely gonna subscribe
I am doing this experiment in school and I plan do to it at home. Earler my teacher showed us this exacted same video and I just now showed it my mother and sister. I really liked this video and I am inspired!!😊
This was so well-demonstrated and explained! Thank you!
That smooth final swollen egg looks soooo satisfying...
Also, my teacher showed our class this to explain osmosis lol
Rakeem B bro that’s why I’m here! 😂
@@owen687 HAHAHAHAHAHAHAHAHAHAHAHAHA WHAT
same!!
Same lol
Im doing a science project on "naked" eggs so this vid is very useful! Thanks!
Allie Panti You're very welcome. How did your project turn out?
This is a beautiful and entertaining video. Thank you. The purpose of the blue dye isn't apparent, apart from making the egg quite pretty, since the dye molecules are too big to enter the egg and must simply be binding to the egg membrane.
You earned my sub bros. You two explained it well that i understood it fully just by watching it once xD thanks
Love you so much guys. You help me in my experiment task
You saved me like a WEEK of doing this experiment myself. THANKS A TON!
+Jon Stewart ......for school.........
@Jon Stewart xD
very informative fellas, thanks for putting in the time to show us the facts
magladze Thanks!! Glad you enjoyed it.
why this channel doesn't have a lot of subscriber? they're good at explaining
Hey guys, thank you so much! What an eggtastic video! You rock :D
Bárbara Pagani You are most welcome!! Watch out you are using our own bad puns against us!!
Fun experiment. Shadow star said this experiment was really interesting!! We will be doing the last step tomorrow!! Excited!!
+Karen Oseland That is great to hear. I hope you have fun!!
well, 7 years and i never noticd the existence of this video... untill today lmao
i look forward to trying this experiment with my students!
This video was really helpful for a school prac... thanks!
This explains it sooooo much better than my biology book like I couldn’t understand the book and after watching the video it turned out to be this easy
love ur profile pic
I came here to answer my take home lab questions. Thx for the help!
My school did this as a 7th grade take home lab
+Icefreak That is awesome!!
Thanks, this helped me with preparing for my science test :D
Thanks guys, this was really helpful.
Thank you for this lovely information!!
You guys are doing very well, keep it up!
2:11 OH very cool.
Btw, watching this late at night for online school
This experiment is really interesting.
I want to do it with my students after the school suspension.
Thank you, perfect experiment for my 5th grade daughter who is studying osmosis! She loved it!
Michael Long That is great to hear :) I am glad that she loved it!! I hope that she will continue to enjoy and love science!!
What grade is she in now
Well then you have some catching up to do :) We have a lot of fun ones planned for this summer so stay tuned :D
Lonely comment
7 years ago dam
@@seanl191 yeah
lol ikr dude
You guys rock! Thank you for the detailed explanation!
You can also see this osmotic shrinking and swelling with umibudo (sea grapes), no shells in the way!
I wonder if a test like this with an egg in a solution can be used to show whether or not certain chemicals can pass through our skin such as in cologne/perfume, lotions etc.
our teacher are recommending your videos thanks a lot for this information
This was a great video!
Wow!!! This was reallllyyy amazing
You are very helpful because of u I scored full marks in practicals
I won first place in my science fair with this experiment thank you so much
Good job on the video, I just discovered your chanel and Im following you! :)
Thanks for the compliment and for following us!! Let us know if you have any suggestions for experiments
seeing how i have vinegar with my egg and this takes to long ima go and make and eggsplosion x3
I've learned so much.
I am curious to know what happens if you break the blue egg as it is clear the colorant is on its surface. Listening your explanation it is clear to me that the colorant should remain on the surface of the egg, however it should not going inside. If you break the blue egg, do you find the colorant inside or not?
appreciate the video...what are some examples of osmosis in the plant or animal cells.
Hey guys! I have a question... I want to make this with my kids (I'm a teacher) and I was wondering if I can use maple syrup instead of corn syrup? It's just because it's easier to get 'cos almost all the corn syrups here are transparent and I think the color it's a special feature... Thanks! Amazing job.
Good job 👍
hi school friends!
now i dont know what your sheet looks like but heres some of it i hope (:
Osmosis : osmosis is the tendency of water to move across a membrane from a dilute solution into a concentrated solution
Time stamps : credit to milo
Normal egg : 0:58
Vinegar: 1:12
Corn syrup: 2:05
food coloring 2:49
can you use golden syrup instead of corn syrup?
Hi! Thank you for making this vid! It's really good :-) I would like to ask, why would the surface of the egg harden when exposed out of corn syrup?
The air will dry it I think
Yaayyyyyyyy I definitely absolutely totally 100% want be here
Doing this for my science fair soooo cool!!!!!!
+Alani Taylor Awesome!! Good luck!!
Thanks for explaining this, it sums it all :)
Thank you ! Sci Guys now i have a presentation to show infront of our class ;) Naked Eggs are like Alien Eggs ... U guys are very COOL :) New Subscriber Here !!!
Ma.Rowena Ferrer You're very welcome!! Thanks for all the compliments and for subscribing :D Good luck on your presentation!!.
Thanks for the video! I have to do a comic on osmosis for Biology and this really helped me understand it!
Melody Trancy You are very welcome. I am glad you liked the video.
That was easy to understand
Easy to understand
can the corn syrup be substituted by psncake syrup?
what will be the reaction of the egg if its solvent is water?
Pretty video!
Hi, Thank you for the great science experiments, I use them with my grade 5 students. I would like to do the naked egg and osmosis experiment but corn syrup is very hard to get in Australia, particularly where we are. We're in rural Tasmania. Can I substitute with granulated sugar and warm water?
love it. thanks
It would also have the same effect if we replaced the corn syrup with extremely salty water, right?
Great experiment. You should probably clarify that the blue-coloured molecules in the food colouring can move through the semi-permeable membrane into the egg, causing the egg to take on the blue colour. It's not just water that can move. :)
thank you! I am home sick and was given this video as part of a lab I was unable to attend. one of the questions was "Does blue dye move into or out of the egg?"
I HAVE NO IDEA! Thanks for the clarification.
@@Tanneremerson You're welcome. It is quite simplified, but not only water can move through a semi-permeable membrane, but also other small molecules like the dye molecules which give the dye its colour..
this experiment can take a good 1 week to complete but question what do you do with the egg after you are finished like if you know what to do
who is with me
Thanks guys! I did this for my science fair and got 3rd place
Jethro Gibbs Congrats!! Keep up the great work!!
Totally Awesome
Is the blue food coloring not a molecule too? If the egg membrane only lets water pass, why does the blue color pass too?
Hey thanks for the video guys. What I don't understand is why the egg became bigger (absorbed water) when it was placed in vinegar, the acetic acid. Is this because the concentration of the egg was higher than that of the vinegar, and so the water traveled into the egg because it was placed in a hypotonic solution? Thanks and please reply!
Can you use clear corn syrup instead of the brown corn syrup?
anthony hernandez yes u can it works the same way
if it's dense it will work.
We're doing this for our lab in Bio 12 right now. I'll get my lab buddies to send our results. :)
Would you say there was lore liquid in the cup before you let the egg sit in the syrup for a day than after or less?
I have one question that-- is it important that we keep the egg in vinegar only can't we keep the egg in water as only water molecules are travelling in wards egg shell???
do you have the measurements of the egg? like the mass and circumference??
Can we use salt and water for the alternative ingredient for the corn syrup?!
Can u use vegetable oil instead
Is there anything I can use instead of corn syrup that will lead to the same result? Thank you for your help.
It's the classic reply after way too long, but I'm assuming any kind of thick syrup with lots of sugat would work, based off of the video. Maple or golden syrup maybe?
What is the egg's membrane impermeable to? Also, did the solutes inside the egg diffuse out of the egg?
Hai...thankz...great demostration! very like it! =D
hamim tm You're welcome and thanks right back at you!!
Today's science lesson, ladies and gentleme: Corn Syrup shrivels your eggs. That's one more reason not to drink coke!
I'm almost certain that's not how it works. Salt makes snails shrivel up and die, but is that a good reason to stop putting it on your food?
@@ryangallagher9723 Halfpast3am is correct. Sugar drinks are know to dehydrate the body. Which is why you need to stay away from them when you need to hydrate.
@@vekuhnvowles6270 Um, okay. I honestly forgot I posted this comment, but thanks for your insight.
@@ryangallagher9723 Bro, the oxigen gas also destroy iron. You guys should stop breathing.
Does that mean if I drink vinegar I will become hydrated?
I AM GONNA TRY THIS LOOKS FUN 🤷♂️
Can you make experiment on preparing semi permeable membrane
I did this in school!!!! It was SUPER fun!!!
Caleb Eufracio good for you 👍
how do you keep egg down the corn syrup for 24 hours without holding the spoon?
Does it work with maple syrup instead of corn syrup?
that works so much thanks
Can you use the dark vinegar?
Is there a better alternative to the old spoon idea? I don't think my mom would like me bending one of her spoons, even if they are "too old".
can we use any other type of syrup instead of corn syrup?
Instead of corn syrup can I use Honey as the alternative?
this really helped me thx a lot
are you the arabi from our school
who are you
What will be the independent and dependent variables?
Help pls
Do I have to use corn syrup? Or will any dense liquid work?
Thank you so much is so AWESOME.
Louise Maree Glad you enjoyed it!!
You guys are awesome!!!!!!
Makenna Kungle Thanks!! You're awesome too!!
We put the corn syrup egg in vinegar and the egg stayed shriveled. Is that because of the acidic properties in the vinegar?
Does distilled white vinegar work ok? and is a brown egg ok?
Thanks for the love :) You keep watching and we will keep making them.
