Bring in an egg to school, Was 6 years old, My mum was clever and drained the egg out by using a needle to make a small hole.
The rest of the class brought in smashed up eggs and I was the only one with an intact egg
Teacher then procedded to use my egg in a demonstration, showing how an egg was impossible to break from the top with your bar hands. The point was to get us to understand the strength of certain shapes and structures etc.
