I used to work for
a research company who used to muck about with scarily powerful microwave
systems for industrial use...
My eyes were
soon opened into the huge potential of microwaves for arsing about and much fun
was had blowing stuff up!
Anyway, here’s
something equally spectacular that you can try in your own microwave oven at
home – Lightning in your kitchen!!
Good innit? What
you’re seeing is ‘plasma’. Normally at
atmospheric pressure, electrons in the air inside the flask are packed so
tightly together that they can’t move about much when smashed with
microwaves. In a partial vacuum however,
they are free to move around a lot more. When a microwave hits an electron, it
can now knock it clean away from the proton & neutron, ionizing the gas
into a plasma.
It’s exactly the
same phenomenon that makes lightning, the Northern Lights, low energy bulbs and
plasma tellies etc.
Putting an upturned CD into the microwave can be pretty cool too, but I didn't tell you that....
