Think about this: an egg’s diameter is much bigger than a bottle’s opening, but still it’s possible to stuff an hard boiled egg down a glass bottle without breaking the egg or the bottle. The bottle would probably break if a bigger object was stuffed down the bottle. How is that possible? Watch and try this experiment at home:
1. Why does the egg need to be peeled before starting?
2. Why does the flame stop burning once the egg covers the opening of the bottle?
3. Before the experiment, is the pressure inside the bottle greater, less or equal to the outside? How about during? After?
4. Explain using pressure, the flame, and Amonton’s Law, how the egg is able to squeeze through the tiny bottle opening.
5. How is the guy able to get the egg back out through the opening?
