WOW! Did you know that what Peter is holding is in fact an EGG?!
It is so swollen and almost transparent looking... how could it be an egg?
Peter has done a pretty cool experiment at home where he has put an egg into vinegar over night. This has caused a chemical reaction that has dismantled the egg shell!
What happened to the shell? Just like our teeth the egg shell is made of calcium and like teeth it can be corroded by acid. Interesting stuff!
Thanks for sharing, Peter.
What do you think Peter, shall we try this experiment in class next week?
Lets give it a go!
