Egging me on

The British Egg Information Service developed an egg emblazoned with an invisible ink label that turns black when the egg is cooked. The new eggs will go on sale this fall. From the Times Online:

All you need to do is decide whether you prefer your eggs soft, medium or hard-boiled, and buy accordingly.

A spokeswoman for Lion Quality Eggs, the service’s quality assurance scheme, said: “We had a lot of inquiries. We said OK, this is a big issue — people can’t even boil an egg.”
