- Science/Engineering Presenter Garry Lavin shows us that eggs shells aren't as brittle as some might think. In this video he lays bricks on them to show an egg shells sheer strength. He also uses his drawing skills to show why they are so strong.
Live Experiments:
Our resident daredevil science fiends will give the RUclips audience their big science treat each week with an experiment where you can find out how to make food dance, power a light bulb with household objects and create mega smoke rings!
RECIPE
IMPORTANT: You will need one sober adult with a sense of scientific wonder...
What you need to get started is: 6 eggs (You only need 4 but I'd advise 6 as a precaution), 3 bricks, a bowl, masking tape, a marker, a tablespoon, a knife, scissors and some old sheets of newspaper
1. Place some old newspaper on your work surface to keep your home clean
2. Tape one strip of masking tape around the centre of the egg
3. Get a marker and draw around the centre of your strip of masking tape
4. Use you table spoon to hit one end of your egg to make an indent
5. Then use a blunt knife to pierce through the indent and drain your egg
6. Once the egg is drained carefully cut around the line on your masking tape (It has to be perfect or the egg shell will collapse under the strain of the bricks - so take your time.)
7. You can now remove the masking tape from your egg shell - repeat this process until you have eggs shells of equal size.
8. Create a rectangular shape with 4 egg shells that will be used to support your bricks.
9. Line up a brick so that the for corners will are evenly distributed on the egg shells
10. Place one brick at a time on top of the egg shells
11. Remember to stand well back after each brick is laid on in case the eggs collapse.
12. Stand back and leave for a 10 second interval before you place on your second brick
13. Stand back for another 10 second interval and then lay on your final brick
14. Slowly remove the bricks once you have completed this experiment"

3:20 I STARTED DYING I LOVE TITANIC
And the list of stuff I didn't know until today keeps growing. Thanks!
They had a similar problem with the first jet liners, until they cottoned onto the problem of metal fatigue. Hence why rounded cabin windows became standard.
I'd like to see how far you could push this if you could measure and position everything really, really precisely.
I like how the presenter isn't like a presenter.
Strength to weight ratio is more impressive when you think about the weight of 4 eggshells and one brick.
That's because it's a normal wall building (Or 'London') brick. They're meant to have a hollow on one side.
It's so when adding the brick to a wall that's being erected, the cement can stick inside this hollow, giving a brick wall more strength. It's why they are the most commonly used wall building brick. They're lighter, stronger and easier to work with.
I hope this helped and indeed enlightened you. :)
Actually, shapes created by chains and ropes are NOT parabolas! They are described with special equation and called Catenary! Check here en.wikipedia.org/wiki/Catenary
My thoughts exactly! Matt Parker taught me this.
👉🌹I love this subscriber because the explenation is superb .......🌹 👈😊😊😊😊👌👍👏
I worked in a brick factory for a while, in between computer jobs. The hollow is called a Frog and its original purpose was to reduce the amount of brick tax payable to the government. The Frog is still there simply to lower the manufacturing cost (less material) of each brick.
1:07 it is not a parabola, it's hyperbolic cosine. I've calculated on a standard physics course at the university how a string or chain hangs freely with both ends tighten up, and the result is definitely cosh.
No, the titanic broke in half because the bow filled with water and tipped the ship upwards with it's stern clear out of the water. The compartment system in the titanic caused this unusual sinking. If the ship was damaged in the center it actually would not have sunk or split in half.
parabola is y=x^2
catenary is y = cosh(x) = (e^x + e^-x)/2
They just look similar
I have to admit that was a slip of the tongue, with Titanic being shorthand for big ship. But ships have round portholes because stress starts in corners and has been known to begin in such a way and travelled around the hull so that the ship breaks in half after a stress event a lot less than an iceberg.
So many bad egg puns! Still a great show!
eggsactly! the perfect DESIGN for maximum strength.
It is Hyperbolic but sometimes best to keep things simple for a quick TV piece.
@3:15 when the iceberg hit the titanic... because an iceberg all of the sudden jumped in front of the titanic... lulz
Entertaining stuff . .nice alternative delivery !!
I'm wondering if they could be left whole and supported in the carton to avoid having to do the tedious cutting operation.
and all falling things technically follow an ellipse, not a parabola, they just reach the ground before they can change direction in the x plane
1:00 technically that is a catenary, they are different, parabola is y=x^2 a catenary is y=cosh(x) or y=(e^x + e^-x)/2
Puns...puns everywhere.
A hanging chain forms a catenary, not a parabola. Also, a thrown projectile follows an ellipse, not a parabola.
eggcellent puns good sir.
That was a eggcellent eggsperiment
amazing
These egg puns are getting eggstremely out of hand.
Let's face it: we wanted to see him throw the egg at the bricks and watch it somehow break them.
Anyway... it was a cool eggsperiment
great episode :)
The hanging chain is a catenary, similar to but not a parabola.
They should stop yolking around with those egg puns.
Is there any other alternative besides using eggs to strengthen the bricks? sorry we need it for our research
They would've been much stronger if you hadn't cut them in half, just supported each one with a bitof sand or flour
eggsalent explanation
The shape of the chain is called a catenary I think, not a parabola
I just had an eggsesential crisis because of the amount of puns in this video...
eggcuse me, pls stop because but those puns are eggausting
i managed to. but damn! did it take some effort...
I was eggstremely eggsited about the amount of eggtaxtic and incrdibly eggstresting things in this video
the shape of the chain is a catenary not a parabola and projectiles follow elliptical paths not parabolic paths
Without the tape it would have caved much sooner i believe.
Cos it would be harder to hand-make a bed for them to sit in. Actually, I suppose you could use an egg carton... But then maybe people would say that it provided extra strength so was a cheat.
"Its the shape [Which sounds like he says shit], the shape!" LOL! :)
holly shit that the stig!!!
when u cut an egg, u damage its integrity. whole eggs can easily support 4 bricks. the title is very misleading: ur not really comparing the strengths of the two materials. ur looking at how many bricks 4 eggs can support. having said all, the video is very much appreciated. thanks
He cut them at about 2/3 of the way down. I wonder if that's because 2/3 is a Fibonacci approximation of phi.
Try leaving the fresh eggs as they are (without removing the white and yolk) but secure them to a table/floor to keep them standing. Repeat the part of the experiment where the bricks are placed on top of the egg shells and see what happens. (:
But when it gets crushed it will be a mess YOU have to clean 😂 not fun
+Emy Young The egg is the strongest at the top and the bottom (or at the highest point of the arch). If you hold an egg in your hand and squeeze it on the top and the bottom, the egg doesn’t break because you are adding pressure to the ends which are the strongest parts of the egg. #funfact :))
Through the year some months have 31 days but others just have 30 days. How many months have 28 days?
Nope. Cosecant section of a graph does not equal, nor have the properties of a parabola. They just look alike.
I think they got the idea from Nottingham Science.
Which is incorrect?
1-The yolk of an egg are white.
2-The yolk of an egg is white.
3-The yolk of a egg is white.
This doesn't prove that eggs are stronger than bricks but just that eggs are strong enough to support bricks.
But I pretty much bet that 4 bricks would be able to support three other bricks...
humpties revenge
Possibly, but it's not done with as much finesse here.
Oh my God, 3 brick?!
It's not a parabola, it's a catinary arch.
Eggs stronger than bricks are quite misleading. This experiment simply shows how strong egg shells are but it definitely did not show whether an egg is stronger than a brick.
thats actually a hyperbolic sine...
i thought the yolk was yellow :P
Ah. Fair enough.
Can the maximum weight of those four eggs can take be mathematically calculate? If yes what the formula?
too many egg puns !!!
When he took off the last brick it looked like the one under it was hollowed out.
You are supposed to hold a knife by the handle...
Did you know, yolk from a raw egg gives you dieria?
0:26 look at the bricks, they are all like that.
After 8 years!
funny they just had to use this example :D
The 'coming up' bit at the start is not the best way, or the most professional way, to start a show. Look at how Jonathan Paula starts 'World According to Jon' and try something more like that.
Don't think this guy quite understood why the titanic sunk...
so if i put 4 eggs on top of one brick ....... what does this prove? lol
when he got to 3 I was eggstremely tense, in fact I was bricking it.
Its a lot less fun when you realize those area dead baby birds :(
they should do > can paper hold my weight
I thought it would hold 10 bricks...
I thought the egg would hold the fourth brick..
Of course not. But they can be stronger than you think. and possibly stronger pound for pound as they say.
Nooo... A catenary and a parabola are two different things
So how does this experiment show whether an egg is stronger than a brick?
Should have left the eggs intact.
I tried to squeeze an egg in my hand.. They are harder to squeeze than the look... Seriously, try it.
Just tryin to help out
I'm just wondering why these are in my notes-
Not really. Eggs for consumption are unfertilised.
Why cut them up?
Also half egg ≠ parabola.
I have no problem admitting I'm wrong but I'm not sure about your theory mert. Don't sound quite right to me ,bricks being produced so heavily and all. But to find out I suppose we're on the right You Tube channel. Yo! Head Squeeze, answer this one for us. :)
TSM Egg Zero
Same
SO EGGS ARE NOT STRONGER THAN BRICKS LOL
when I did it I got 100 bricks on it
yeah i know lol it was eggsactly 11 o clock and i was tired
i was just thinking that
Catenary ≠ parabola
All of them
Stop, you're egging them on!
eggsplanation?
now do the opposite! 4 bricks on 3 eggs and see if it lasts!
3 bricks*
Missleading title
