Cow Egg
The Cow That Laid an EggMarjorie is an insecure cow who wishes she had some special talent. She can't ride a bicycle or do handstands like the other cows. Then one morning (thanks to a bunch of scheming chickens and a paintbrush), Marjorie is astonished to discover something extraordinary : shes laid an egg !
But does the baby inside the egg really belong to Marjorie? Emotions run high in the farmyard as everyone waits to find out !7.9.10

Eggs Can Swim !
How it looks :
You drop an egg into a glass of water and ask the audience, “Can anyone make this egg float to the top of the glass? With a pinch of magic potion and some magic words, I will show you how to teach an egg to swim!”
You take out a plastic bag and take a pinch of “magic potion” from it. You sprinkle a few grains of magic potion into the glass while stirring it with your finger. “Now, for the magic incantation. From the depth of this glass filled to the brim, wake up little egg, it is time to swim!” The egg rises to the top due to the stirring, but sinks back to the bottom of the glass.
You add a spoonful more of the magic potion, stir the glass and say the magic words again, louder this time, “From the depth of this glass filled to the brim, wake up little egg, it is time to swim!!” Again, the egg rises and then falls back down.
You pour the rest of the bag of potion into the water, stir and scream out, “Swim! Swim!! Swim!!!” This time the egg rises to the top and stays there even after the water stops stirring. You smile and say, “Sometimes it just takes a bit of egg-couragement.”
What you need :
• A clear glass of room temperature water (just large enough for an egg to rest on the bottom of the glass)
• 1 egg
• Salt (6-10 tablespoons or 90-150 mL)
• Small bag or container (non-transparent – something that you can’t see through)
• Tablespoon
• Adult helper

• Small bag or container (non-transparent – something that you can’t see through)
• Tablespoon
• Adult helper
How it works :
The “magic potion” is just salt hidden in the plastic bag. When you add salt to the water, you make it heavier, or more dense, than the egg. This is why the egg floats. With a bit of experimenting, you can add just enough salt to make the egg float halfway up the glass.
Did you know…
If the egg floats before you add salt to the water, it may not be a fresh egg.
When an egg is first laid, it is warm. As it cools, the contents contract (shrink) and form an air pocket at the large end of the egg. As the egg ages, this air pocket grows in size (air replaces gases that escape through the egg’s pores), making a “lighter” egg that floats!

Adopting an Egg
And tango makes three, 2005

Age: 4-8
A children's book about an orphaned penguin egg given to two males in the Central Park Zoo who adopt the egg and raise the baby as their own.
The book is based on the true story of Roy and Silo, two male Chinstrap Penguins in New York's Central Park Zoo. The book follows the six years of their life where they formed a couple and were given an egg to raise.
The book has won many awards but also been at the center of numerous censorship and culture war debates on same-sex marriage, adoption and homosexuality in animals. The ALA Office of Intellectual Freedom of reports that And Tango Makes Three was the most challenged book of 2006 to 2009 (wiki).
Reasons are : anti-ethnic, anti-family, homosexuality, religious viewpoint, and unsuited to age group.
"We wrote the book to help parents teach children about same-sex parent families. It's no more an argument in favor of human gay relationships than it is a call for children to swallow their fish whole or sleep on rocks."

Everything From the Egg
De generatione animalium (1651)- detail -
From William Harvey, by Richard Gaywwod
Writen on the frontispiece of "De generatione animalium" (1651) :
Exercitationes de generatione animalium. Quibus accedunt quaedam de partu : de membranis ac humoribus uteri & et conceptione
London : William Dugard, for Octavian PulleynThe Aristotelian William Harvey is most famous for discovering the circulation of blood, but his work on reproduction was important too. He opposed earlier theorists who believed human life began with a seed produced by the male. Harvey theorized that all life came from eggs : not only for birds, but also for mammals. Because the microscope had not yet been invented, he had no way to prove his theory, but he became famous for the dictum "Ex ovo omnia" ("all from the egg").
The engraved frontispiece of his treatise "On the generation of living creatures" - detail above - shows Zeus (Jupiter) opening an egg and releasing all forms of life into the world (humans, other animals and plants) and so drew on earlier representations of Pandora’s mythical box.

Omelette
OmeletteThéâtre d'objets, de Marie Gaultier et Nathalie Gallard
A partir de 5 ans
La compagnie angevine Piment Langue d’Oiseau s’est interrogée sur la société de consommation.
D’un petit jouet à peine visible sur la scène, sorti d’un petit œuf jaune lui-même sorti d’un œuf en chocolat, « Omelette » raconte un combat contre… le vide. Le plus important, ce n’est pas l’œuf, mais le neuf, la nouveauté, la surprise. Le plaisir ne dure pas longtemps. Le neuf devient rapidement vieux et appelle à la quête d’un nouvel œuf, puis d’un autre. De chacun sort un objet qui, une fois découvert, devient vite banal et inutile. Les coquilles s’amoncellent, les objets, minuscules et dérisoires, aussi. L’ennui s’installe… puis reviennent les rêves.
