How to Cook the Perfect Hard-Boiled Egg


This Flash application from the University of Oslo figures out the optimal time to cook a hard-boiled egg based on four factors: the egg's circumference, the level of doneness you want the egg to be, the start temperature of the egg, and the elevation you're cooking at.
