Eggs-periment! (Part 2)

Following yesterday's little experimentation session, we found some time to allow all the K2 students to test the squishy-ness of our squishy eggs. Priceless were the expressions we saw, from utter amazement, to absolute delight, to complete disgust!

                                     

Squish!

So, did anybody manage to figure out the answer to our three questions?

1. Why does one egg stop spinning while the other continues?

2. What is the item used to balance the second egg?

3. Why can the second egg stand when placed on top of the item?

The children did!

First, we had a few volunteers help us spin the eggs and stop them to see which egg continues spinning and which egg stops.

 Then, we cracked both eggs open to see the difference!

Crack! It's raw and gooey!

This one's nicely cooked all through!

Ah! So, that's why! The raw egg continues spinning as the gooey yolk inside the shell also spins!

Now, what about that balancing egg?
We called Janiel to see if she can make an egg stand on a the table.

And then Nicklesh help us make it stand on the mount of salt (yes, the secret is salt!).

 But why does it work that way?

Well, the perfect cubes of salt grains form a nice and stable pedestal for the egg to balance on. That's why!
