Why you fill the kettle to maximum level when want make a cup of tea?

You shouldn't fill the kettle to the maximum level when making a cup of tea! Here's why:

* Safety: Filling a kettle too full can cause it to boil over, potentially scalding you or damaging your stovetop.

* Efficiency: A full kettle takes longer to boil, wasting energy and time.

* Waste: If you only need one cup, boiling a full kettle wastes water.

The ideal amount of water to boil depends on how many cups you want to make. A good rule of thumb is to fill the kettle about halfway for a single cup.
