When I was a kid (during the 80’s) I bought a “square egg maker” at a garage sale. It was a plexiglass cube with cranks that could be used to reduce the size of the cube after placing a hard-boiled egg in it. After some time passed (hours? maybe a day?) the egg could be removed from the cube and the egg would be compressed into a cube shape. Even the yolk inside the egg would be cube shaped.
This is why egg-coloring kits come with a dye tablet you dissolve in vinegar then soak the egg in the vinegar solution for a minute or two. The vinegar softens the hard shell enough for the dye to penetrate and stick. Without it, the dye won't stick. FYI you can use regular food coloring and vinegar, and you can make the wire thingies you use to move the eggs in and out of the vinegar out of large paper clips.
Quite the contrary my fellow proud citizen of the universe. There isn't much value to store an egg in a bottle (besides, how do you want to get it out as soon as its in there?) the square box on the other hand is stackable and saves more space than an egg carton.
A very cool video with some interesting, easy to reproduce results. Thanks for sharing with us a lovely simple experiment that is safe for all ages. :-)
This was before Carbon Dioxide was going to destroy the world, back when climatologists (like 'father of Climatology' Reid Bryson) claimed the Earth was still cooling and an ice-age was going to kill billions from starvation by the 2000s.
I love how this is always suggested after a new Curiosity Show video where Deane is the host. That said, I tried this and forgot it for 2 days. The egg grew and the white of the egg turned to vinegar.
These are the television programs which inspired the scientists of today. This show, Mr. Wizard here in America, and many others made science fun and entertaining. I’m very happy to see them live on in RU-vid for our children to enjoy and learn from.
"The Ooh Ahh bird is so named because it lays square shaped eggs." Classic line from '70s Brit sitcom The Good Life where Margo reads out Tom's homemade Christmas cracker joke.
Wish you would have explained exactly what was going on to shell. Like is the shell completely gone and that's just an interior lining that's made of a similar material as reptile eggs? Or did you chemically change the calcium of the shell and that made it soft. Guess I'll have to give it a goog and find out
It’s easier to just warp the local space around the egg by transforming it from Cartesian to inverted polar coordinates. That way you get cube like eggs. Not perfect but it works well enough. The only thing you have to be careful of is switching back to regular space when cooking them or a singularity might form.
I saw this trick on a book when I was a kid. The book mentioned that the egg would have bounced, but it didn't mention to do it from a low height. So I let the egg soak in vinegar overnight (horrible, horrible smell) and the next day, lo and behold! the egg is in fact rubbery. Confident, I pick it up and throw it on the floor, only to see it break and make a mess. Moral of the story: don't always trust what you find in books.
@@CuriosityShow seeing the egg with its translucent membrane in your linked video was pretty cool. I might have to try this to see it up close. It would also be interesting to test the elastic limit with many rubbery eggs sandwiched between two tables as if it were a sandwich and two of my childhood TV presenters, a cameraman to garnish the sandwich like your balloon experiment!
I wonder if it's healthier to eat the eggs whole like that, once cooked. I'm wondering if the membrane under the shell has a higher concentration of nutrients but since it stays attached to the shell when cracked normally, are we throwing away the best part? Like peeling vegetables?
There is almost nothing of nutritional value in the membrane, it's largely just a bit of collagen. The shells however are ground up and sold as calcium supplements, as they are almost entirely calcium.
The best way to think about it is by examining the purpose of the membrane for the growing chick. Of course when a chicken hatches it doesn't eat its shell. The nutrients it was getting while growing inside of the egg were in the yolk and not the shell. So for predating animals, the bulk of the nutrients are logically in the yolk too.
I guess put the jar with the egg inside in the fridge until its cold then hold it upside down and shake until the egg gets stuck in the neck. Then warm it up and the expanding air inside the jar should push it out.
When I was in middle school, one of my teachers told me the saying about how “Columbus’s friends said it was easy to make an egg stand on end after he showed them the trick” and then she asked me “so what do you think the trick was?” I went home for the weekend, and this was essentially the solution I came up with, and I have always wanted to see someone else do it. The teacher was a good teacher, and both told me the real solution and gave me praise for out of the box thinking, and I think that is why I eventually became a game designer. Columbus’s (supposed) solution, btw, was to file down just a little of the flatter side of the egg until it stood flat.
I’ve known this for years, but this really old video taught me something new! I thought the vinegar did something to the egg to make it bounce. But when he said you can still use it, I realized that it’s bouncy because the vinegar only melts the shell and not the albumin which lines the shell! I never realized the albumin was so tough.
One of the main reasons I like older generation diy experiment tv shows is that the experiment never wastes material. The egg is still edible and they certainly consider the wastage of food.
The Curiosity Show (1972-1990 ) hosted by Rob Morrison and Dean Hutton was an entertaining kids science show produced before Australia became an authoritarian regime . Good ole days down under .
This reminds me a little bit of that legendary Donald Duck comic "Lost In The Andes", by Carl Barks, where Donald and the nephews find square eggs that are made by square chickens.
shortly after this aired, the chicken industry put into practice large scale acid washing of eggs, and thats why we buy eggs today from the shops in little square boxes and jars, instead of cartons
At the risk of sounding like some sort of freak, I'd like to know what happens with a fertile egg with life inside of it when exposed to the vinegar. Does it harm it or is the shell strong enough to protect it for short amounts of time?
Unfortunately, if eggs have been refrigerated, then they need to stay that way. Leaving a previously-refrigerated egg out overnight will cause bacteria to form inside the egg. And no, the vinegar has nothing to do with keeping it fresh.
