It's well known the Americans do quite a few things different to us Kiwis down in the Southern Hemisphere. While most of our differences are just water under the bridge, Buzzfeed has pointed out the way most Americans do one simple kitchen task and it has people around the world shocked and 'disgusted' at their methods.
The task of heating water is a simple one. Fill up the jug/kettle with water, flip the switch so it heats. The switch flicks itself off when it's done and there you have boiling water.
But, it turns out a lot of Americans don't own jugs so they heat their water by filling up a mug and placing it in the microwave.
Many people have vented their frustrations with the procedure online.
