Superheating Water in a Sealed Glass Bottle
tesla500, Fri May 26 2006, 07:54AMWhat happens when you put water in a bottle, superglue a metal stopper in, put it in a microwave, and get out of the room? 12 minutes and approximately 160 deg. C later:
Full Speed: (60fps), 3.9MB
Slow motion:(5fps) 2.0MB
The results quite literally blew away our expectations. When the bottle broke, the force of the flash boiling water blew the door open, the edge of the door moving at over 60km/h. The entire garage was filled with a cloud of steam, and glass shards flew everywhere. Please DO NOT try this at home unless nobody is in the room and you don't care about the microwave.
Next experiment: microwaving a fiber-glassed egg.

That's.... interesting ^^
See, kids, this is why you don't put sugar in your coffee straight after it's out of the microwave

>_< the same thing happens, but on a much smaller scale, if you forget to peel back the corner on your TV dinner. Now I'm going to go eat my pasta explosion.

I was on a guy's website a couple years ago. He was talking about the day he put one of those "Blue Ice" things in his microwave, so he could keep his meatloaf hot or something. He said it about gave him a heart attack and it blew the door completely off.
What a moron.

Interesting...I guess that makes taking apart a MW oven a little easier...now you can do some MOT experiments

You should try microwaving some beer.

"Its even wrecked the beer fridge"
LOL
Is it just me or is that a bit fake? Either that or the 5% or so alcohol really is fuelling it?

It is a fake, beer does not combust nor detonate.

the link to the video doesnt work for me, but if it is the one I am thinking of it is not a fake.
The way it works is as you microwave the liquid it heats up, normally it would boil but since it is in a sealed container it just builds pressure (look up a vapor pressure/temp curve of water, at 200c the vapor pressure of water is like 200psi! So as the water heats up it stores up all of the energy until the container eventually breaks. The causes the water to be at 15psi (1atm), so it can boil. So all of the energy stored as it heated up is suddenly released as the water boil and you end up with superheated steam... Which creates the explosion.
This would happen to water heaters before they added pressure relief valves. If the burner were to get stuck on it would heat the water until the tank burst... Then all of the water boils and the whole things takes off like a rocket, and blows right through the roof and goes a few hundred feet!

Fiberglassed egg eh? I don't know about that.
But I tried MW a normal egg(just woke up, what do you expect?), BOOM!
scared the crap out of me.

I saw a video once in chem of a corked off bottle exploding in the microwave once... No idea if it is public or not, very impressive none the less

Probably he's sayng about (by description) about the first event (just water bottle).
It's completely normal for it to explode when heated up to insane levels.
I also couldn't see the beer thing but if there was some kind of big firey explosion then it's obivously a fake.
Beer wouldn't differ much from water bottle in any way.

I can't get the video clip to work but I can still say that beer doesn't burn.
God help anyone who does that with vodka.
If anyone is stupid enough to try it
1 don't blame me.
2 do it outside by remote control.
3 take a video of it.

I think we all concluded about the beer.
Something with more alchohol percentage may get potentially flammable when it gets so hot, but it may need some help to ignite.
Maybe some steel wool could be stuffed inside rof a trigger.
Not to mention how dangerous this would be, except for the oven you must not care for the building/room as well, as you are very likely to start fire and have a big explosion if the vapour does really ignite.

lol, leave that beer alone. Films from that page are 90% fake anyway.
For those who don't believe, tow frames while oven is actually 'exploding' :P :P

I think it's a bit suspicious that he says that it has been going for ten minutes and that it will explode any second. It's obviously fake
