Superheated water in the microwave oven

Do you usually use your microwave oven to heat water, for instance to prepare a cup of tea? If you do and you had no accident yet, you are pushing your luck. Take a look at what can happen in the video below. AND DON’T TRY THIS AT HOME, SERIOUSLY.

This is due to the water being in a superheated state, or in other words, having a temperature larger than its boiling temperature. The superheated state is unstable, and it can very rapidly turn into liquid at the boiling point, plus a substantial quantity of vapour.

ferrofluid

“ Ferrofluid is a very interesting material originally developed by NASA it has now found itself been used for a whole range of devices including dampers for controlling and stabilizing large building that move around in the wind. Whats also amazing is that they have such lovely visual qualities when magnetized. “
