The Sci Guys: Science at Home - SE1 - EP14: The Naked Egg and Osmosis

Welcome to the fourteenth episode of The Sci Guys. In this episode we will be investigating an experiment involving the creation of a naked egg and then going through the process of shrinking and growing our egg through osmosis. We will show you how you can explore this topic at home with a bunch of simple household items and a laser.

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?

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.

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?

[@hazelalbiar_]

Is there anything I can use instead of corn syrup that will lead to the same result? Thank you for your help.

[@nediah]

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?

[@lizzirockwell8919]

Does it make any difference if the corn syrup is dark or light? Does it just affect the tint of the egg or i the dark corn syrup necessary for the reaction?

[@TheSciGuys]

Lizzi Rockwell It shouldn't matter which you use and yes it should only change the tint of the egg. Just make sure you are using a corn syrup that has a really high sugar content.

[@brandondesouza6451]

What is the egg's membrane impermeable to? Also, did the solutes inside the egg diffuse out of the egg?

[@powereln]

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?

[@khadijawilliamson2272]

appreciate the video...what are some examples of osmosis in the plant or animal cells.

[@HSFY2012]

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. :)

[@Tanneremerson]

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.

[@HSFY2012]

@@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..

[@jeffl2248]

Hello! In school we did an experiment similar to yours. We put or egg in Vinegar, Corn Syrup, and then Water but then we put it back into Vinegar or some other classrooms put there egg in Coca Cola.

[@TheSciGuys]

BOB JEFF Cool! Did you have fun doing the experiment? Also what did you observe about the egg when it was placed in vinegar again or the coke?

[@jeffl2248]

The Sci Guys Well when we but it in the vinegar again we kept it in the vinegar for about 2 days and you could see the membrane (before we couldn't see it) and when we started to move the egg around. You could see the yolk inside it. All our egg mass for the second time of putting it in the vinegar was 2 times bigger than a raw egg. You guys should really try doing that... :)

[@TheSciGuys]

BOB JEFF I am curious if coke would dissolve the membrane or not.

[@jeffl2248]

The Sci Guys Well my class didn't soak the egg in Coke so you'll have to experiment it yourself Sorry :)

[@raheelarabi]

who are you

[@bubblecubes1735]

This experiment is so cool! I tried it and it turned out really well. But what would happen if you put it in food coloring first, that corn syrup?

[@TheSciGuys]

Bubblecubes Here is my prediction. If you take your naked egg directly from the vinegar stage and place it in water with food colouring, the egg may grow slightly bigger and will also probably absorb some of the food colouring. If you then place it in the corn syrup, it will shrink all the way down like it did in our video. You should try this at home and let me know if my prediction is correct.

can the corn syrup be substituted by psncake syrup? what will be the reaction of the egg if its solvent is water?

[@AmiyaRoseWickWasHere]

Could i use dark corn syrup and get the same results? Also would Apple Cider Vinegar work, or do i need to use just vinegar?

[@TheSciGuys]

+AmiyaRoseWickWasHere Dark Corn syrup should work find as long as it has around the same level of sugar. It just might look a little darker in colour. Apply cider vinegar will work as long as the concentration of acid is the same as normal vinegar and that often depends on the brand.

[@andrewkim1806]

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!

[@TheSciGuys]

Ather Aziz Soy sauce may shrink the egg a little bit, depending on the ratio of salt to water. If it does shrink it probably won't be as dramatic as using a syrup. The soy sauce will also probably colour your egg a dark colour. You should try it out and let us know what happens!!
