Poached Egg Physics

You will need:
 * Two pots - one tall and narrow, one short and wide
 * 4 cups water
 * 2 raw eggs
 * Slotted spoon
 * Timer
 * Use of the stove (ask for adult permission or help)

Pour 2 cups of water into each pot. When the water boils, poach an egg in each pot for 2 minutes. Quickly remove the eggs with slotted spoon.

The yolk of the egg in the tall pot gets harder than the one in the short pot because the boiling point in the tall pot is higher, causing the food to cook at a higher temperature and making the cooking time shorter.
