Naked and Bouncy Egg Experiment
What happens when you put an egg in vinegar?
This is a fun science experiment that would show you how to make an egg bounce “literally” by removing the hard shell that covers the egg leaving only the membrane.
Once the outer shell is removed, the membrane covering the egg is not as “fragile” as the shell itself, as a result of this, you can easily bounce the egg (gently) without breaking it.
This experiment takes a week to carry out, but it sure worth the wait. All you need is a tall glass, vinegar and an egg. Check out the full procedure here.
Egg Osmosis Lab Experiment
This experiment would show you some crucial biological process that plays an important role in our daily activities; Osmosis and diffusion.
The setup for the egg osmosis experiment is quite similar to that of the bouncy egg experiment. The main aim is to remove the egg shell without removing the outer membrane that covers the egg.
Because the egg membrane is permeable to water (much more than the hard shell), then liquid materials can move in and out of the egg, it all depends on the concentration of the environment.
Using the egg osmosis lab experiment; you can artificially increase the size of an egg, or decrease the size.
Here is how to setup the egg osmosis experiment:
Materials Needed For Egg Osmosis:
- Eggs (About three)
- Tall Glass
- Karo Corn Syrup
- Place the three eggs in a bottle filled with vinegar for 24 hours. The aim is to make the eggs naked by removing the egg shell. Read the egg in a vinegar experiment for full guide on that.
- After 24 hours, remove the eggs from the vinegar bottle and place them gently in an empty plate.
- Fill a tall glass with Karo corn syrup and another glass cup with water.
- Gently place a naked egg in the Karo Corn Syrup and another into glass filled with water.
- Leave the set up for few hours or a day if possible.
- Gently pour the solution in each cup into the drain and observe the egg.
If done properly; you would discover that the egg in the corn syrup would shrink and they albumen would be gone leaving only the yolk.
The egg in the water solution would have increased in size greatly and as a result you would have bigger egg than normal.
You just performed an osmosis and diffusion experiment!
What does osmosis means?
Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Source
The concentration of the Karo Corn Syrup is higher than that of the egg albumen, and as a result; the content of the egg would move through the egg membrane into the glass filled with Karo Corn syrup until the concentration of the solution is balanced. This explains the egg shrinkage.
What does Diffusion means?
Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential). Source
The egg has low water concentration and as a result, water from the glass would move into the egg to increase the size of the egg.
Major difference between Osmosis and Diffusion?
Osmosis requires a semi-permeable membrane while diffusion does not.
Egg in a Bottle Experiment:
Of all the science experiment involving eggs, I find this one very interesting, reason being that, it relies on advance science techniques of air and pressure relationship.
A slightly advanced principle is also used in making aircraft and elevator. But for now; let’s focus on how to get an egg in a bottle using this technique.
The aim of the experiment is to get a hard boiled get into a glass bottle through the small opening of the bottle that would not allow the passage of the egg under normal circumstances.
This method uses the science of partial vacuum to forcefully push the egg on top of the bottle inside the bottle.
Check out the full procedure on how to get an egg into a bottle here.
Floating Egg Experiment
This is a fun kitchen science experiment. There are two major ways to get an egg to float in water:
You either get a bad egg and put them in water. The bad egg would float in water because it now contains much air and it’s density (weight) is low compared to the density of water.
Another method of getting an egg to float is by increasing the density of water such that it weighs more than that of a good egg.
You can do this by adding a handful of salt to the water so that the density of the water would be higher than that of the good egg.
Want to see how it’s done? Check the floating egg experiment.
Egg Reshape Experiment
This is a twist of the rubber egg experiment, and it’s a little bit complex to carry out. You can check out the full procedure here.
Glowing Rubber Egg Experiment
The procedure of creating a rubber egg with glowing is very similar to that of naked and bouncy egg.
The principle behind the experiment is such that; you would carefully remove the hard shell of the egg using vinegar (it may take a day or two) by soaking the egg in a cup filled with vinegar.
How to make the egg glow?
This is where the twist comes in…
Instead of soaking the egg in ordinary vinegar, you can go ahead and add some food coloring to the vinegar. And before you know it; your egg would change to the color of the food coloring after the experiment.
The principle behind the color change and glowing is that of egg osmosis as explained earlier in this post. Check the full procedure for here.
Unbreakable Egg Experiment:
Can you break an egg by squeezing it? Let’s find out!
This is definitely one of the simplest egg experiment in our archive. Using this experiment, you would learn about the strength of egg shell, and how evenly distribution of pressure can help sustain the shape of an object (even eggs! as fragile as they are)
We all know eggs are really fragile! A hard drop on the kitchen table would break their shell and make everywhere messy. But what happens when you apply pressure on an egg with your hands evenly? Would the shell still break? Let’s find out in this simple unbreakable egg experiment.
This is one of the egg strength test.
- An Egg.
- Nylon (a transparent film; a cling film will do).
- Wrap the nylon around the egg.
- Place the egg on your palm and squeeze with ALL you strength.
If you feel like you’re not strong enough; enlist the help of an older person and tell them to squeeze as hard as they can.
All things being equal; the egg would be unbreakable, even if the might hulk is squeezing it on your behalf.
Egg has an oval shape, which means the weight is evenly distributed all over it. Think of it as a balanced system. As a result of this; there is no weak point on the surface of an egg shell.
When you squeeze on your palm, no matter how hard you try; the pressure you’re exerting is also evenly distributed on the egg across it’s shape, so the force is not really affecting the egg strength.
Advanced Egg Science Experiments:
Egg Drop Experiment
Completing this experiment might be intimidating at first, but once you master the process then you would be good in no time; and you would be glad you dedicated you time in the first instance.
The aim of the experiment is to find a way of protecting a falling egg from cracking or breaking.
While this post would not provide a clear cut outline for the experiment (I have never tried it myself). I will share some egg drop ideas with you and also point you in the right direction.
Egg drop ideas:
When creating your egg drop project, you main aim is to find a way of altering the natural environment into which the egg falls by creating a device that would protect the egg.
Think of it as putting a coke in a refrigerator during hot summer. Even though the weather is hot; you would still have a chilled coke right?
So the main idea is to create a comfortable environment for your egg as it falls through gravity.
You can think of padding the egg with foams, or get a way of keeping the egg afloat while it drops.
There is a website dedicated specifically for egg drop challenge, you should really check it out if you’re interested in competing in the egg drop challenge.
Have you tried any of the egg science experiments, where you able to pull it off appropriately? Did you run into any difficulties while carrying out the experiment? Do you have any other cool science hint you would like to share with others? Kindly make use of the comment box!
