a gasoline can in a microwave, and turn the MW on. About a minute later
the house exploded. The good part is that it shows the house explode,
so most people would not do it, but the bad part is that it gives
criminals ahd mentally deranged people another means of destruction.
Then we wonder why we have all these shootings and other forms of
violence. I dont know what the program was, because I was not really
watching the tv, I often just have it on when I'm working on stuff, but
I saw it, and thought that was a real stupid thing to show on tv.

Obviolusly this was just "Staged", probably an empty gas can and
nonworking microwave, but if that was actually done, it could explode
instantly if there was even a small amount of vapors leaking out of the
can.

Day late and a dollar short. Last summer I freecycled a working
microwave. My wife had charcoaled a biscuite in it
and I couldn't find anything that would take the smoke out. Had I
seen this then, I'da been out in my pasture trying it.

Would the gasoline get hot? Microwaves create heat by exciting the

dont contain water (or shouldn't). I dont think it would heat.....

But if any vapors leak out, there is almost a guarantee that some

This makes me wonder what would happen if someone tried to heat some
very high alcohol content liquor, such as Everclear. That does contain
some water, even if it's minimal. I dont see why anyone would heat
straight liquor, but I'm sure that things like a hot eggnog with rum has
been heated. I would guess that the alcohol content is low enough not
to cause an explosion, but the alcohol vapors still have to go
somewhere.

In every microwave I have dismantled for parts ( 50 of them), I have
yet to come across a motor that uses brushes inside of the oven; every
one of them was an induction motor.

There is, however, a relay inside of each of them, and while the
contacts are enclosed, I would suspect that they might not all be
hermetically sealed units.

Put a metal cup in the uwave, filled with any liquid. Both the metal
cup and the liquid in it will heat up, it really doesn't matter which
one heats the other. Alcohol will also heat up, it doesn't have to
just be water molecules that are agitated by the uwaves and get hot.
Take two equal teaspoon fulls of water and rubbing alcohol, put into
two equal-sized pyrex dishes, and turn on the uwave. Both will get
hot and eventually boil off.

Obviously you haven't actually tried this. Metal cups don't heat up, though they may spark (or not, depends a bit on the shape and size). We use aluminum foil to keep the corners of brownies from burning - the metal blocks the wavers.

To be pedantic, a metal cup holding liquid will heat up.

So the soup heats up but the metal doesn't? Interesting. I need to look for a junk microwave and try this again. I've never had sparks unless the metal had corners or sharp edges.

A sealed container is not going to work. In microwaves, it's all about
wavelength. If metal coincides with the proper length, it can form a short.
Create effects. If it's not the correct length, it may not do anything. Try
a 2.1 inch piece of foil, or 4.2 inch, vs a 2.6 inch.

A metal container with a 2.1 wide inch top, should allow the RF to energize
the interior.

I had visions of doing a test. Already threw out microwave, I don't know

that does not happen to the water vapors. There might be some micro arc hot

If there is a small sliver of metal -- aluminum foil for instance --
in the
microwave, it will heat up, melt, and arc.

I have seen this when heating something in old plastic jars that
were
sealed with metal foil. When the foil is peeled away, it leaves
slivers
of metal around the top rim of the jar. If the jar is later used for
keeping
things in the fridge, and put in the microwave for heating up later,
the
metal fringe arcs over. THAT would give the spark if the plastic jar
were filled with gasoline instead. However, for an explosion, it
would
have to happen when the gas-air concentration was correct. Otherwise
it would just start a fire.

Hint: When using these plastic jars, take a knife and scrape away all
the metal traces on the top rim......

Anyway, just thought I would mention it......
