Mouse beep egg / intelligent egg timer

The Mouse PiepEi plays three different melodies for three levels of hardness THE SHOW WITH THE MOUSE - for wimps MY GRANDMA DRIVES IN THE CHICKEN... - for medium-soft eggs OLD MACDONALD - for hard eggs The Mouse PiepEi guarantees the perfectly cooked egg. No matter what conditions you cook the eggs under. It sounds funny, but that's the way it is. Too soft, too hard – but never to the point. Perfectly cooked eggs are a science in themselves. But no problem for the PiepEi. Simply store with the eggs, cook together with the eggs and wait until the Mouse Beeping Egg sings. No matter what water temperature you start with, no matter how many eggs you cook and no matter what height you use PiepEi - the egg will be perfect, because PiepEi works always and everywhere. PiepEi measures the outside temperature with a sensor and calculates the inside temperature in the egg using a differential equation. That was...physical. The Mouse Beeping Egg. A beautiful memory of childhood and the perfect gift for all explanation bears.
