Editing Egg timer (section)

==Technology==
Traditionally egg timers were small [[hourglass]]es<ref name="telegraph prince">{{cite news|last=Prince|first=Rose|title=Christmas wish lists: Hamish Anderson, Richard Corrigan, Skye Gyngell, Rose Prince, Sophie Dahl, Sir Terence Conran, Sam and Sam Clark and Yotam Ottolenghi|url=https://www.telegraph.co.uk/foodanddrink/foodanddrinkpicturegalleries/6709505/Christmas-wish-lists-Hamish-Anderson-Richard-Corrigan-Skye-Gyngell-Rose-Prince-Sophie-Dahl-Sir-Terence-Conran-Sam-and-Sam-Clark-and-Yotam-Ottolenghi.html?image=3|access-date=3 July 2012|newspaper=[[The Daily Telegraph]]}}</ref> and the name has come to be synonymous with this form. {{Citation needed|date=January 2012}} As technology progressed [[clockwork|mechanical]] countdown timers were developed which had an adjustable dial and could be applied to a wide range of timed cooking tasks. Most recently [[Timer#Digital Timers|digital timers]] have also been manufactured and a wide selection of software is available to perform this task on a computer or mobile phone. The task is simple to perform on most microwaves and oven timers.

New products have been developed which potentially allow for better egg timing; these use the temperature of the water in which the eggs are being cooked to indicate the cooking state of the eggs. This kind of timer has the potential to more accurately indicate the state of the egg while it is being cooked as they do not rely on certain conditions (water hardness, hob temperature, atmospheric pressure).

One such product is made of translucent plastic with a heat-sensitive coloured disc in the middle which changes colour at {{convert|80|C|F|lk=in}}. The plastic around the disc changes temperature relatively steadily and gradually from the outside to the inside of the plastic mimicking how an egg heats up while cooking. This allows an observer to see the colour creep inwards through the disc and stop the boiling at the stage required. As it mimics the boiling of an egg, it will be accurate even if the boiling process is disrupted, a lower temperature is used and regardless of the quantity of eggs being cooked.<ref>[http://ergonomics.about.com/od/buyingguide/fr/egg_perfect.htm Egg-Perfect Egg Timer Ergonomic Review] {{Webarchive|url=https://web.archive.org/web/20160409041924/http://ergonomics.about.com/od/buyingguide/fr/egg_perfect.htm |date=2016-04-09 }} About.com review.</ref> Other similar products use electronics to sense the water temperature and play a certain tune or series of beeps to indicate the state of the eggs.<ref>[http://www.brainstream.de/wie_geht_das.html Beep Egg] {{Webarchive|url=https://web.archive.org/web/20110624000247/http://www.brainstream.de/wie_geht_das.html |date=2011-06-24 }} Brainstream.de - Beep Egg product page {{inlang|de}}.</ref>
