Here's a precise egg timer, which is boiled together with the real eggs. Once the yolk and egg-white have reached the desired degree of hardness, the Kiiroitori egg timer will play a tune. To know how cooked your egg is, you need to listen to the following songs:
- Soft: Killing me softly
- Medium: Triumphal Symphony (Verdi)
- Hard: Eine Kleine Nachtmusik (Mozart)

Note: The egg timmer should be put in the fridge, so that it has the same temperature as the eggs when put into the boiling water.
