Tempering can cause glass to explode. Tempering means that there are internal stresses within the glass that result from uneven cooling from its molten state during the manufacturing process due to the glass's thermal expansion characteristics. This can occur due to carelessness or intentionally. So called "safety glass", like that used in autos, is intentionally tempered. If the glass is even slightly nicked, the tempering resulting is stress concentration that can cause a chain reaction releasing all the stress in the glass  in a great low energy "explosion" of glass pellets. The idea is that no one shard of broken glass is large enough to cause serious injury.

Good question,but remember it's a nursery rhyme...You have to associate humpty with something that is breakable and non-repairable..Just happened to be an egg,,Stay sweet..

Sounds kind of dangerous, I'm not sure. Depending on how old it is and what type of tv it is, it could be an exploded tube or fried wiring!

I was baking some brownies.\nThe doorbell rang. When my family member answered the door, I looked up to see who it was...just in time to notice a cup slide across the counter by itself & fall to the floor.\nAs I stood there gasping, I noticed the dial on the stove turn up by itself another 200 degrees.

if the powder size is quite small, eg grains to dust, it can spontaniously explode in air.  Otherwise it just "rusts" to get a layer of oxide like most metals.

Didn't you ask this already?\n\nPretty sure I answered it...\n\nwent something like...\n\nIf I had to take a stab at this I would GUESS it's because the ash is dry and not very absorbent and the kerosene is still able to give off enough fumes to be ignited. However, the soil is moist and can absorb more of the fuel in such a matter than there aren't enough fumes to be easily ignited.\n\nThat's a guess. I have never actually encountered what you are describing.

When the FBI pumps in gallons of extremely flammable substances in order to drive out the occupants, and then the building catches fire, there should be some questions raised.  From everything I've seen, the FBI just made a lots of mistakes and did things in a very poor manner.  This resulted in the compound turning into a cluster f&#%.

Was the glass heatproof or pyrex? Probably the rapid heating caused the problem, not the salt water directly.

Hmmm......\n\nI don't know. I assume things can explode, as long as the essential ingrediants are stored within the object exploding..\n\nHowever, it may be more of an implosion. \n\nSo, yes, no, maybe. Give me my 10 points.

It cant be just any piece of glass, it has to be a prism. The light comes out in the form of a rainbow because the prism separates the light into it's visible colors.

wasent it a glass jar ?

You are exactly right. The energy given to the system when you hit them together was enough energy to break the bonds of the oxide layers on top. The thermal energy of the reaction elevated the electron energy states for a small amount of time, causing them to fall back down to their ground state and giving off some photons...hence the spark.

It could have been shaken loose out of the socket.  However, I doubt that with the amount of force that the CPU fan has on it, it will come off that easily.\n\nThe problem most likely is from a loose Video Card or Memory Module.  Open up the case, seat everything back in by pushing down on them and try again.

What do you mean "surely"?  Where do you get that notion that this is a sure thing?\nBasically, the pancake collapse means that each floor above would come crashing down on the one below with enough force to instantaneously break its support, and then the falling debris gets increased by the weight of this new floor, making the lower floor less likely to resist collapse as you go down.\nAn 8% speed reduction is actually quite a lot.

Sorry but only the first answer was close.  The air inside the baloon is compressed, because of its containmentt inside the stressed rubber.  (You need to blow to fill a baloon).  When the rubber is split, the air expands rapidly to equal the surrounding pressure.  This rapid expansion propogates outward, causing tha bang

Me! my uncle tried to fix his toilet he got really mad at it, so he hit it with the plunger and it exploded and now he has glass all over him and his hand is cruhed...

Its the same principle as a welding arc. when the bulb goes out the philament breaks into two pieces. When they split apart, before they get too far apart, the electricity jumps the gap causing a bright flash. After that the current cant make the leap so the bulb is dead.
