People have been hard or soft boiling their eggs for years, but apparently it’s hard for some to acheive the desired consistency because they have to time the egg boiling. That’s where this new invention, the self-timing egg comes in. This egg has a special heat sensitive invisible ink placed on it that turns black when the egg is ready for consumption, taking away the need to time the boiling. Personally I probably wouldn’t use this device because I am accustomed to cooking eggs the hard way, but for some I guess this could be a great convenience.
