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.

Equipment and Ingredients:
1 x Egg
1 or More Glasses
Vinegar
Corn Syrup
Food Colouring
Water
Old Spoon
Goggles
Gloves
Lab Coat or Apron

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😂

[lupitag]

Oh me trying to do a lab that takes a whole week in one night 🙂

POV: Your biology teacher showed you this video to explain Osmosis

[lelengtintin]

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.

[tmbae]

These guys just saved my lazy ass from actually doing the experiment. THANK YOU 🙌🥺

[ophelia]

welcome class of 2024, to your biology class.

I learn more through the internet then at school

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?

My egg “died” in the colored water so I was screwed. I needed this XD

[rakdok]

That smooth final swollen egg looks soooo satisfying...

Also, my teacher showed our class this to explain osmosis lol

[sorasgirl]

You saved me like a WEEK of doing this experiment myself. THANKS A TON!

[alexpantano]

Im doing a science project on "naked" eggs so this vid is very useful! Thanks!

[gushenry]

This website helped me with my science fair project so im definitely gonna subscribe

[churroman]

2:11 OH very cool.
Btw, watching this late at night for online school

[strawberry-csoj]

why this channel doesn't have a lot of subscriber? they're good at explaining

[lucidia]

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!!😊

[halfpastam]

Today's science lesson, ladies and gentleme: Corn Syrup shrivels your eggs. That's one more reason not to drink coke!

[michaellong]

Thank you, perfect experiment for my 5th grade daughter who is studying osmosis! She loved it! 

[karenmonsrud]

Fun experiment. Shadow star said this experiment was really interesting!! We will be doing the last step tomorrow!! Excited!!

[anthonyhernandez-yfin]

Can you use clear corn syrup instead of the brown corn syrup?
