Science In ACTION! - Regular Glass VS Tempered VS Laminated

Compare differences between regular, tempered and laminated glass.
Glass is one of the most unique materials available to man. Fragile and strong at the same time - it combines the most amazing characteristics. Ordinary, tempered and laminated glass - each has its own manufacturing nuances.

It's interesting that even though the blow is to the center of the pane, the fragmentation begins at the edge/corner and moves across it in a uniform wave. It would be cool to see a video explaining why that is.

It's because the impact bounced the glass, and on the way down it struck the hard steel table. It wasn't the hammer that broke it, it was falling on the table. A similar effect occurs if you were to throw a tiny spark plug at the glass - dramatically less energy than a sledgehammer, but the hardness would still cause it to shatter.

@@forced_youtube_handle Ah I see. So in a sense the hammer was just imparting the kinetic energy for the table to strike the glass that actually causes the fragmentation.

For life saving purposes: the glass on your car can easily be shattered if you aim for a corner. It won’t bust out, but you’ll be able to remove it after it shatters.

​@@MrResin-xk2mfThanks :)

Maybe try some sleeves

6 mm is ok for luminated glass windows?

[@mysticalisland]

hi. depends on window size, but for a "normal" sized, double glass window, 6 mm or in this case 33.1 (3mm glass + 3mm glass + 1mm PVB film) is the standard in my country, and is perfectly fine.

I have a 2023 mazda cx 5 i just learned my front side windows states laminated glass and to add insult to injury i had tint put on my 2 front side windows a week after i got the car which also a protector as well, I'm doomed if I'm in a accident and i can't open my door and my windows are up., 😭🤧

[@laurendaryani4893]

I would take a look at what first responders might use in that situation and make sure that any power tools you would need are battery-operated (I do believe I'd read that a Sawzall could be used to cut through laninated glass, though not sure what's sufficient to make the initial breach of a laminated glass panel. Pick ax? 😅)

You didn’t need that big of a hammer all you had to do was tap the corner but a for effort

1st!
