Take the guesswork out of boiling eggs! Drop the musical timer into the water when you cook real eggs. It measures water temp and calculates doneness of the eggs, then plays one of 3 songs: "Oh Susannah" for soft-boiled, "Take Me Out To The Ballgame" for medium, and "Hail, Hail The Gang's All Here" for hard-boiled! For best results, store BeepEgg together with your eggs, since both need an identical starting temperature. No matter if it will be in the fridge, or some shelf in the kitchen. BeepEgg and the real eggs have to enter water at the same time. Water "conditions" do not matter, though. BeepEgg is neither afraid of cold, nor boiling water. Just put them in the pan together, no matter at which temperature the water is. One BeepEgg can monitor as many eggs as you like during one boiling session. BeepEgg measures 2" long and includes built-in battery for hundreds of uses. Comes in assorted colors (our choice please).
