Have anyone ever had an ordinary drinking glass explode in their hand?

Well I am just letting you know one of the known reason for S.G.E. (Spontaneous Glass Explosions)

if the glass has been weakened sufficiently due to the thermal shock, the glass will explode with the slightest of knocks, leaving you with a hand full of broken glass (if you are holding it) and believe me it goes with a bang. it doesn't have to be hot. It can seem like a normal glass, slight knock or pressure, and bang!!

And no, you can't put a load of glasses in a generator and leave them to explode it doesn't work that way it's down to material thermal and stress dynamics.

But if this does not fit with what you experienced. then there is not much I can tall you short of saying.

You were attacked by a poltergeist.

There does that make you feel better???

One so called uneventful evening a coke glass expoloded in the palm of my hand.
My cat had knocked it off of the coffeee table and it had broke in two. After an hour or so i got the dustpan and brush to sweep it up. Phased by the lack of glass, water that was in it, i placed the bottom of the glass in the palm of my hand. Still crouched down looking at it after about a minute i felt a tickle in the palm of my hand and all of a sudden it exploded! It went up like champange out of a bttle and came down like glitter.
I thought my friend was going to pass out. I too have never seen anything like it! This was about four years ago. Anyone else had anything similar?

Okay i dont believe this. First you say you were drinking a coke. Then it randomly explodes. After exploding your cat knocks in on the ground again breaking it? THEN you decide to leave it on the ground for over an hour, because there is just water in it (you just said there was coke in it so which is it) This whole story is ridiculous.

"The Achille Heel of a Wonderful Material: Toughened Glass"


A quick search on Google provides some information on the matter.

Here is a quote from someone who experienced similar things.

I've got a story that happened when I worked on a cinema.One day I went to open some glass doors for the costumers to go out of the cinema. When I put my right hand on the handler to star to open the door slowly the glass door brooke instantly and completly falling on peaces on the floor. When this happened one peace o glass cut my right hand. Later one colleag of mine told me it was a source of glass cancer the reason for the phenomenon.

I had something similar happen only to a shower door. I just got home from work ( I lived alone except for a cat) and I hear this explosion sound....I went looking all over the house and found that one of my glass shower doors had completely shattered into a million pieces! I got closer and heard them vibrating, making sound, yet there was nothing to create the sound there at the time....and the other shower door is still whole, the medicine cabinet and the mirror and even the glass window are still whole, just that one shower door broke for some reason.

Not an ordinary drinking glass. This happened to a glass pipe of mine which was very clearly marked for tobacco use only. I had dropped it, and although it didn't break initially, the bowl did explode in my hand the next time I picked it up. I've also had pieces of broken window glass crack in my hand after i picked them up.

The way glass breaks is interesting. Cracks snake and spiderweb out from the point of fracture, and the glass continues to crack until the fragments are stable; and the cracks have reached an edge and can thus go no further. This process can continue after the glass has fallen. It can also pause if the overall tension of the glass isn't amenable to the preexisting cracks continuance to a terminal edge, and be resumed if the correct pressures are once again exerted on the glass.

Considering that well close to every single drinking glass will get knocked over or dropped at least once before breaking, it is almost a guarantee that it will have some kind of fatal flaw lurking within it. These flaws can also originate in manufacturing if certain impurities exist in the glass. An already broken glass has far more. It is an interesting effect that you got with your glass. The tickling in your hand was the cracks compounding in the glass, and that is really cool even if it's not paranormal.

example video from discovery.com
Observe the glass outside of the initial point of fracture, and watch the way the cracks form, and how some of the glass continues to fragment and crack after the individual fragments have separated from the pane as they fall. You can also see what almost look like tiny bursts of light in seemingly intact fragments. These are the cracks forming. The bursts of light are refractions from the cracks and probably a few flecks of glass.

This process is also evident in a pile of freshly broken glass, which will audibly crack, squeak, and make tinkling sounds after it has already hit the ground.

The same thing could be at play however, cold water in the glass with the temperature of the room and it's already weakened state. May I inquirer was the room being heated at the time? If not did you feel any unusual changes of air pressure, or even a feeling of static electricity?

No air pressure in a home, or static electricity, or the grade 1 science class about hot glass under cold water lesson you taught us (which has absolutely nothing to do with his story, so I dont know why you posted it), is going to cause this event to happen.

The fact that, as he said, it exploded upward would suspect some sort of force from below the glass.

Reading comprehension fail.

On topic, I've had similar things happen with glass and the scars to prove it. I'm not so sure it's paranormal but probably has an underlying scientific reason. Harmonics seem to be the best answer but so does stressed and fractured glass. Being that it happened so long ago, there might not be enough evidence to really pinpoint what happened.

It sounds like a bunch of hairline fractures created an unstable lattice within the glass. Because it was left on the floor with a bit of liquid in it, the water and the air drew heat out of the lattice, slowing the molecules down. When you picked it up, you initiated more tiny fractures to traverse through the lattice making it unstable. This effect, coupled with the heating and excitation of the molecules from the body heat of your hand made it appear as tho the glass spontaneously shattered when it fact is was slowly shattering the whole time but you could not perceive it.

Yeah, I was rapidly stiring a handled gass mug with a square pattern like a frag grenade, with a spoon...
suddenly the glass just exploded....

I had just pored in enough boiling water to melt the coffee and sugar, but then filled the glass with ice cold milk...
the spoon was klinking away
poof!
glad there is no rug in the kitchen

It was a green coke glass with water in it. Cat knocked it over and it smashed into two halfs. Hour or so later i retrieve the two parts of the glass. One is effectivly a tumbler with a smooth edge. I sit staring at it for about 4 minutes. All of a sudden i feel a tickle in the palm of my hand that the tumbler is standing in. The tickle gets faster, then boom!!! The thing explodes in front of my eyes and my witness nearly passes out.


I don't know, that's why i'm here!!!

I never said i was drinking coke!

A decade ago, it happened to me once; I was in a coffee shop with my buddies....suddenly I saw my ex went on a date with her new bf.....glass of ice coffee in my hand just explode

Yes, in the 1980s, in New Zealand, there was an epidemic of exploding glassware called 'Arcoroc'... it was very fashionable at the time - tempered smoked glass used for dinner plates and mugs...
I had an Arcoroc mug of warm tea fall to pieces in my hand! Other people had their dinner sets explode under the evening meal.
Arcoroc is still in use. But they've fixed whatever the problem was..

Thank you Vicky,
I remember that too. infact a cup and saucer made out of that exploded in front of me once. It was a coffee coloured glass. French, i think. Was in Luminarc?

This with the coke glass was very different. I could not se any fractures in the glass, before the tickle happened.
Sorry im not very fast on here. I will try and keep up with everyone.

Well due to the tingling sensation it sounds paranormal and electrical to me.

Anyone here have a spirit pass through them ?

The ultimate cold/chill sensation.

Making me think of what the OP has described.....

We've all had glasses break due to falling or due to thermal shock.

Also glass can and will break due to high frequency vibrations caused by sound waves (remember the memorex commercial?) leading to shattered glass.

But also, in order to do this, the source of the speaker must be pretty close to the glass. Because it's really the air waves compressed by the speaker that are impacting the glass causing it vibrate and eventually to fracture.

And it also requires plenty of volume and a high enough frequency to do this as well ...

The OP said that he/she felt tingling right beforehand which leads me to believe that it might have been paranormal spirit energy causing this vibration which in turn caused the glass to vibrate and later explode.

I know that it sounds bizarre but all in all , and taking a step back to assess things here.

What caused the tingling sensation ? A sensation normally associated with electrical current or water current ?

If you have ever had the misfortune to Have ever been zapped by household wall current before ....

It is A most unpleasant experience I might add, but you do and can feel the tingling sensation of the alternating current
similar to what the OP is describing !!!!!

once lived in a very unnerving house where windows broke a lot. There were loads of glass panes in the house so perhaps law of averages, but one memorable time, I woke up from a nightmare, went to leave the house as I was feeling nervous and needed some air, and as I lifted my hand to shut the door behind me the huge glass pane shattered.

If this really happened as described, one thing is clear: the "tickle" was produced by vibration of some sort.
The same vibration also made the glass break apart.

That much, I think, is certain.
The source of the vibration cannot be identified via the internet, obviously.
But I would look for it, for I doubt it's beneficial to your health.

What was your emotional state at the time?
Did you perhaps have an unspoken desire for your friend to leave, or were you innerly annoyed somehow?

I recall getting intensely annoyed but saying nothing in a pub once, and when I touched my glass it just seemed to suddenly "melt" into two pieces, with beer spilling all over the table and my knees.
That sure broke the tension, and refocused the whole evening away from tension, and how amazed me and everybody else was.

I think, especially in your case, there is something "psychic" about it.

It did really happen and i must add that i had the glass at arms length. I was kind of examining it. my arm was out straight, as was my hand with the glass/tumbler.
Apart from sleep paralysis, it was one of the most peculiar things that have ever happened to me.
My friend, by the way was just as shocked that i wasn't shocked.
I was in two minds to contact cococola, but there was no real evidence as the glass had exploded and came down like glitter. The water had completely vanished, which i thought was odd and i was still finding the odd shard of glass here and there weeks afterwards.
My friend, who is not here was a sceptic, but not anymore. He would back me up and would go on a polyograph test with me.
Sorry, but this is very true. I have been a bit dubious of glasses since, but you can't stop using glasses can you?

I believe this explains it best:

it's down to material thermal and stress dynamics.

Must have been a frightning experience.
The glass must have cooled down unevenly when it was formed during production, generating stresses along the surface, when it broke that tension changed and the slightest touch in the right place, or a warm hand, released that tension.
Have you ever seen how they make swords? They put it in oil (in hollywood they use water) as fast as possible to cool down, if it doesn't cool down evenly, the sword can bend or break because of the uneven stresses.
