The shatter proof film does increase the glass's resistance to being broken, and when it does get broken, the pieces are stuck together and don't collapse into sharp fragments. It in no way means the glass is unbreakable though, a strong enough force can make a hole. It certainly could not stop a bullet, which would punch right through it.
A bullet travels at really high velocity and therefore the glass does not have enough time to bend due to the force and shatter instead the bullet just damages the area it gets in contact with and thus making a hole in the glass. Whereas a stone travels at a low velocity and the glass has enough time to bend and shatter
It would be possible for a .22 bullet to brake the first pane and not damage the second. I would expect to find signs of a bullet hole in the broken pane. But it depends on the temper of the glass. High tempered glass will shatter. You usually find these in sliding doors. I knicked one and it cracked over the entire door. WIthin the hour it was a heap of broken glass on the floor. It is possible.
Yes, the glass bottle will shatter.
It is usually made from a combination of two or more types of glass, one hard and one soft. The softer layer makes the glass more elastic, so it can flex instead of shatter. Bullet-resistant glass is usually constructed using polycarbonate,thermoplastic, and layers of laminated glass.
The sound waves produced by the vocal chords contain energy and this energy is transmitted though the air to the glass, sound waves are pressure waves. The glass vibrates in resonance with the pressure variations and energy builds up in it to the point where it can shatter.
The ability of a singer to shatter a glass is a result of the control that they have in frequency. These singers can control high frequencies well enough to focus them to shatter the glass.
I was shattered.
Sometimes a glass is tuned to a certain frequency or note. If a person hits that note, the glass will shatter.
Glass can shatter; it can create glass shards, uneven and jagged pieces.
If you drop the glass, it will shatter. The mirror was going to shatter when it hit the floor after falling from the table.
If it is regular glass then it will probably shatter it. If it is Plexiglas or another form of reinforced glass it may not shatter it.
Most likely you are referring to Westmoreland Glass, a Pennsylvania Glass company that produced a large variety of milkglass. However, the Hazel Atlas Glass company also produced a fruit goblet with a straight stem.
