Severe changes in temperatures can shatter glass which often happens in car windshields. If there is a chip or crack in the glass and water penetrates it and freezes it can shatter glass especially if it is tempered. Heating can expand the tables frame and crush the glass but other than an object falling or direct pressure...ghosts?

There are many ways to break glass without touching it. Here are a few methods:

To do it with sound you need a sound that is a resonant frequencies of the glass you want to break. A sound that is the right frequency with enough volume will put energy into the glass and break it. Glass is one of the easiest materials to break using sound although any object can be broken using sound.

A high enough air pressure difference on glass surface will cause it to break.

Electricity at a high enough power can also break glass but it must overcome the non-conductive nature of glass before it will break. Even once you overcome the non-conductive nature of glass the heat generated by the electricity is what truly breaks it.

Rapid temperature change (hot or cold) is the most common ways that glass is broken without any

I'd like to know too cause it just happened to me. One side shattered, but i don't see any impact point that may have caused it. Could be extreme temperature changes.

No, the glass ball would probably break. And the rubber ball allows for an elastic collision.


Can thunder break glass?

I was recently watching an episode of mythbusters and they successfully discovered that a bullets so called "sonic boom" could not break glass, even though the bullet itself came within an inch of the glass traveling approxamitely 1,984 mph. Throuhgh research and calculations, I have found that thunder travels at about the same speed as sound, which is 1,200 mph. And because thunder is the most common form of a "sonic boom", thunder alone, even if the lightning that caused it was within an inch of glass, would not break the glass.


How many pounds of pressure does it take to break a car side window?

Since it would probably be tempered glass, 100lbs. of pressure.


What does it mean when you hear a glass break?

Ultimately sound is the result of something pushing air back and forth. These pressure/displacement disturbances travel to your ear drum and cause you ear drum to vibrate at the same frequency as the object that disturbed the air in the first place did. In the case of a glass breaking, at moment the glass, say hits the floor, the entire glass would vibrate for a very short moment. After it breaks into pieces, the individual pieces would begin to vibrate at their higher natural frequencies. All these vibrations eventually find their way to your ears by way of the air. Also, it means it's time to buy a new glass.

Who invented toughened glass?

Toughened glass was first invented by a glassmaker who wanted to make a windscreen for a vehicle such as a car or a train so that it would break into lots of tiny fragments that would cause less injury to someone if they were thrown through it if the vehicle was involved in a collision. (If ordinary glass were used it would crack into large pieces which would badly cut that person.)

How high do you have to be to break glass?

You don't necessarily have to go so high to break a glass, rather it is hitting the exact same frequency of vibration that the glass has. So you would tap the glass to determine the frequency (you need someone with perfect pitch or an analyzer), and then you just have to hit that same note at the right intensity to break the glass.


Should I go to the doctor with a glass injury on my foot?

Yes I would tell you to go to a doctor because you could get blood infection and need an operation. This would happen if the glass is still in the foot, or your foot could of got a minor break and if untreated it could cause it to get worse.
