The fat end of an egg has a small air bubble. When this air is heated by the boiling water, it expands and causes the egg shell to crack. Solution? Use a pin to make a small hole into the bottom of the egg before you boil it.
For a start, what's the opposite of the fat end of an egg? Is it the sharp/acute end of an egg?
Second, could I replace crack with break and split without making a change in meaning?
Is "Solution?" shortened from "What is the solution?"
I imagine it's called the pointed end...never thought about it before! You could, I guess, replace "crack" with "split", but not with "break". This would suggest that the damage to the egg is much worse than a split or crack.
