When I lived in the freshman dorm here at school a guy stuck a fire extinguisher in the microwave. A friend found it and unplugged the microwave before it went off. The fire dept said that it could have taken off the entire corner of the building.

I once stripped the insulation off an extension cord, wrapped the bare wire around a .22 LR and plugged it in (while lying behind a pile of bricks). The result: VERY loud explosion, blue flames about 15 feet tall, a complete absence of any casing fragments, and one burnt wall receptacle.

Hey, I was young, stupid, and trying to figure out how to make a detonator.

I got the exact same effects when I wired up a 6 volt toy car motor and plugged it in the wall...except the 15 ft flame was a really cool purple

Something tells me that a link to "Unwise Microwave Oven Experiments" is appropriate:

Back in the days before I actually blew myself up , we did stick an icepick into the powder section of a loaded shotgun shell. A suitable length of 3/32" cannon fuse was inserted, lit & walked away from.

The resulting "nothing" was pretty much that.

No compression chamber = no contained/directed anything.

The shot kinda stood still (as it was the heaviest mass - although it did go a few feet under not much velocity) & the shell flew about 20 feet.

Nothing you'd do in your pocket but doubtful that it would have any effect other than to (perhaps) dent the MV interior (if that would even set it off).

Published results of various rounds being cooked off due to fires (a firemans' thing, for obvious reasons) showed that nothing really happens other than "pops," etc. and the case itself (being lighter than the opposite mass) usually goes further than does the "bullet" itself.

A chambered round is most obviously a whole 'nother matter as it is contained and channeled = a cook-off is just as "much" as if fired from a standard trigger pull in a firearm.

Munro......that is a kool site.

I have three microwave ovens. One of them still works but has some interesting scars.

All the ones I have had were fan ventilated, they don't seem to hold much pressure. Made a real pretty jacobs ladder with two wooden dowels soaked in chlorine bleach then stood them in the oven in an upright vee pattern. The corona around each dowell was augmented by the lateral arc moving up and down between the sticks....beautiful.

Rumor has it that microwave is not a real good way to dry freshly washed brass, lots of pretty arcing tween the necks and altered structure in the brass.

Cooked off paper hull shotshells don't do much but you will have the problem of burning cases smoking up the place.

If you get a fire goin in one, don't open the door, turn it off and the fire should oxygen starve.

CD's are pretty impressive in old microwaves. I discovered this quite by accident when a friend got a little tipsy and couldn't beat Street Fighter EX on his playstation--to him, it seemed the obvious solution was to nuke the game CD as an example to the others not to get uppity.
We've been nuking old CD-ROMs every once in awhile ever since.

I do have another friend who claims he used to put .22 rounds in a vice, with the primer pointing up and just the bullet itself in the jaws, and then whack it sideways with a hammer. Said it was kind of neat but it was dumb luck whether it would ignite since you'd knock the case off the bullet and the powder was down against the bullet itself. I say "dumb" is the operative word....

Didn't Gen. Hatcher detonate all common service cartridges(of the era) inside of a pine box with one inch walls? Nothing, incl. the .50 cal. pentrated through.

I believe if you surround metal with material that doesn't reflect microwaves back into the feed horn butt obsorbs them you could eliminate possible magnatron damage. This would not inhibite desired effects since microwaves cook from the middle. Therefore I recommend to insert one live round into rear of cat, dead or alive. Then microwave till detonation.

Try this (I'm serious, it's really cool and won't hurt anyone).

Materials:
2 Forks
1 Pickle
Old lamp cord with plug still attached.

Stick one fork into each end of the pickle.
Then attach the wire to each fork.
Lay the pickle on a concrete floor or other dry, non-conductive surface.
Then, plug it into 110AC.
Stand back a couple feet.

Do this outside, or in the garage.
Why? Cause it stinks, ALOT.

What does it do?
The pickle begins to fizz and steam, and in a little while it will begin to glow orange.

My physics teacher in HS showed us that.
Then, for extra credit I made an electric chair (about 10 inches tall) and dressed up a pickle in dolls clothing.
I brought it in and executed the prisoner.

Fun stuff!

My HS chemistry teacher showed us the glowing pickle trick. Except he made us sign a contract saying that we would never, ever attempt this experiment unsupervised.

RAJ - I've got all the needed equipment cept the Microwave!

Being from the big city why don't you check out some pawn shops on you jaunts around town. Find a microwave for a fairly cheap price and we'll have at it when you come up.

That's easy. Ghostbusters.

Crossing the streams would be bad.

Ok I am a little fuzzy on this whole good/bad thing.

Imagine all life ceasing to exist.....


I am not sure this is exact but it is close and I know its the correct movie.

I'd bet it would go off. Don't use a rotating plate one, that way you can sort of direct the bullets path.

I do know an egg will explode(covering the entire interior with cooked egg) in a few minutes on high. If you're gonna do it, do it in an "enemies" microwave.

FYI - cockroaches do die if microwaved. Someone told me they didn't, we just had to find out.

ok, you want the ultimate in psycho experiments.

My seniors Physics high school teacher told us this story from his university days waaaaay back when. His university lecturer in advanced physics had an experiment constructed to demonstrate that fissionable material, in this case reactor grade Uranium would became strongly attracted to another mass of Uranium especially if the 2 halves approached critical mass. A rig was constructed using 2 hemi-spheres of U-235 (I think) that were themselves attached to powerful retaining springs, there was said to be sufficient mass of the 2 combined spheres to create a critical mass. Anyways after several succesful demonstrations of the 2 halves stretching the springs in an attempt to come into contact with each other, they finally managed it. They immediately began to heat up and showed signs of melting despite the best efforts of the tutor to separate them, he eventually managed it by pulling them apart with his bare hands in a moment of sheer panic. He was said to have lasted for 2 weeks before succuming to radiation poisoning. I have never been able to verify this story but it has never been far from my mind these last 20 years.

I seem to recall from my days in college, learning all about radiation and such that microwaves react with water and metal molecules. With water, the temperature reaches the point at which steam is created.
With metals, the temperature rises to infinity.

Mike H, that story is true but it didn't happen at a university, it happened at the Los Alamos lab during research for the Trinity project. The physicist's first name was Michael, but for the life of me I can't remember his last name. Maybe it'll come to me later. Too much radiation for me also during the formative years, I guess.

I remember watching Newton's Apple a decade or so ago, and saw something really cool.
They had a steel ball (4" dia) that had a 1.5" hollow inside, and there was a .75" threaded hole in the side.
They filled the ball with water, screwed in a steel plug, and dropped it into a pail of liquid nitrogen.
(Which was inside a plexiglas box)
In a few seconds there was a big explosion.

Water expands when it freezes.
It has lots of power, and obviously was not contained by the steel.

I think someone wrote this, but I'll say it again. Microwaves (MW)work by exciting molecules, water molecules specifically. If you take something that doesn' have any water in it, like Sugar, and microwave, the end result is the same sugar you put in. depending on the climate you live in, the plate you put it on may not even get warm. so, the power will not heat up, assuming it isn't wet or something and the primer is mechanically activated (needs to be hit by something.) so it shouldn't go off in the MW.

but, the casing and if you are using a jacket round, that jacketing also will produce sparks. lots of them. like RAE said. lots and lots of sparks.

There are 2 things stopping me from trying this at home is
1) my IQ. It is somewhere above 55
2) i don't have a MW that I can use for the test

It ain't mah fault. did I do dat?

If 45King can find a cheap MW we'll be testing in the following order...

Primer

Powder

Live Round (.308 lying down, and just to make it interesting a .454 Casull standing up at the same time)

Guess my IQ is &lt; Chink's!
