BeepEgg - The singing floating egg timer Too hard, too soft – but never on point. A perfect boiled egg is a science in itself. Dead easy for BeepEgg, though. Simply store it with the eggs, boil it with the eggs and wait until BeepEgg sings. Christmas BeepEgg How does BeepEgg work? BeepEgg constantly measures the outer temperature. With this data it calculates the core temperature of the egg. BeepEgg knows at which temperature each stage is perfect. Once the egg has reached the desired stage, BeepEgg will play a melody. Each edition plays three melodies, each melody signalizing one level of hardness. These three different tunes will each be repeated several times to meet the egg sizes as well as personal fine tuning possibilities. BeepEgg works at all altitudes and under all conditions. You can use it during diving excursions (you’ll need a submarine, though) as well as on the Himalaya or at sea level. Boil one egg or twenty at a time, start with cold or boiling water. BeepEgg is always on point.
