How does the toast in the toaster pop up?!
i'm doing a report on toasters :DWww@FoodAQ@Com
Answers:
In older toasters, the hot wires heat up a small device called a thermocouple!. When it reaches the right temperature, which is about the same time as your toast is properly toasted, it releases a catch allowing the toast to pop up!. At the same time, it shuts off the electricity!. In some newer toasters, the thermocouple is replaced by a small timer!.Www@FoodAQ@Com
