Try your hand at making your very own Mini Miss egg stool at home.

What to do:

1. Weigh the items and make a note of how heavy they are.
2. Place the egg cups on a table.
3. Place the eggs in the egg cups.
4. Now, position the eggs and egg cups so that you can balance the large book on top of them with one egg acting like a 'leg' at each corner of the book.
5. Choose an item and place it on the book - watch the eggs and see if they crack - hopefully they won't.
6. One at a time, put the rest of the items on the book. See how many you can place on the book without the eggs cracking.
7. Try it again using new eggs, this time use the lighter items first - can you now put more items on the book without the eggs cracking?

When you place items on the book, their weight is pushing down on the eggs. You might think this would make the eggs crack straight away, but eggs are actually surprisingly strong. The force of the push from the items is actually spread all around the egg's surface, meaning that it doesn't crack - hopefully.

Also, here we are using 4 eggs, so each egg is only taking ¼ of the weight of the items, which is why you can put more items on the 'eggy stool' than you might have expected.
