Gav and Dan use some absolutely insane frame rates to learn how fast 5 millimetre tempered glass cracks. 3 pieces of glass were harmed in the making of this video.

Hello everyone. I recommend you watch this one full screen or on a computer so you can see the cracks more clearly. They look bloody tiny on a phone screen! - Gav

So if the earth was made of glass, it would take roundabout four hours till it is completely shattered into pieces.

The speed of glass as measured from a front-on shot is not accurate, because the glass was bent into a curve.

When a crack in safety glass extends due to thermal stresses from the defroster, it progresses slowly and majestically across the bottom of the windshield until it gets in front of the driver. Then, it makes a right-angle turn and goes upwards.

Hey Guys you said "Laminated Glass" "Wrong" the glass you were using was heat treated, safty glass. Laminated glass would not have seperated from the laminate film in between sheets. Other than that it was amazingly fast. Great Job.

Shouldn’t different types of glass break at different speeds? If so, then your whole experiment is invalid.

Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph.

The problem here is that your measurements are being affected by the properties of the paint that held the glass together on one side. Maybe do the background in different colors vs painting the glass to get more accurate measurements.

Cody Silcott महिन्यापूर्वी

FYI, you are using tempered glass (safety glass) for this experiment. Tempered glass is meant to break this way. So in case the glass does break, it breaks into tiny bits as opposed to big shards. Try using Annealed glass, which will give a more “glass break” look. Great video btw! Love the channel!

I wonder if they cracked it in two places if it would create an interference pattern on the crack front of some kind.
