How fast does glass crack? - The Slow Mo Guys

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

Then why no sonic boom

It’s actually spherical. Doesn’t look that way with a flat sheet but it radiates out in a spherical pattern.

In case anyone was looking for the short answer it’s approximately 3,000 mph. So almost 4X the speed of sound.

Any info on ruperts straw shatter speeds🤔

Without the paint, the speed would surely exceed 6,000 km/h.

Mach 4.3

Dear Gav and Dan - please time the breaking speed of a Prince Rupert's drop

Mach 4.2 gives the best idea

Dude I did not see him holding the glass at the beginning hahaha😂

Painting with Dan in SloMo?

I bet tempered glass is faster than normal glass.

Does the paint slow it down?

Fun fact: if the earth was made of glass, we’d all die.

Woww

I’m not sure why I find it so weird but it’s interesting that the glass cracked at almost a mile a minute, just under actually. But converting the speed to KM/hr it ended at the exact amount of feet that a mile is, 5,250. Idk I just find it odd when things align like that lol 😆

Does thickness make a difference in the speed??

How many speed does glasscrack

I wonder how many glass blenders they had at the end of this?

I think the one foot paint markers may have affected the cracking speed a little bit.
like it might have acted as some sort of elastic band I guess?

Faster than a bullet

On TAOFLEDERMAUS, they drove an aluminum airsoft BB at 5,266 ft/s (1,605 m/s)!

Amazing speed but keep in mind the paint probably slowed it down.

If only loading bars moved that consistently 😔

Anyone else surprised they are using feet and not centimeters given the way they talk.

Interesting ... I am willing to donate a sheet to cover the bloody fence ...

I wish I could live wherever these guys live, where it's perpetually summer

ok, am I the only one who is fascinated by Gav HEAR, its litterale perfect :o

What I would prefer as an answer is why the initial break propagates into millions of pieces where as old glass would only turn into shards?

I was curious ok?

"there's a dislike button too that's always fun"

Not anymore. RIP.

Did anyone else not even notice the glass in Dan's hand at the beginning until he said "oh here's one!"

“What goes Mach 4.2 apart from spaceships?”
Spaceships, which go at Mach 23: You underestimate my power!

God loves you❤

Wow, that happens to be almost exactly the speed of sound in water!

I watched the slow mo guys at double speed and there's nothing you can do about it

you mentioned lizard skin as a benign simile but there you go. dispersion of force follows the path of least resistance and the same goes for pathways of force dispersion amidst cells in plant leaves and animal skin. the same physics that determines the shape of glass shards determines the veins in leaves and the patterns of cells on your joints. anything that flexes when it wasn't originally built to do that is going to need some way of getting rid of excess force and those patterns are it

Mach 4.2 🤯

I love to see things animals like us are not supposed to see

Fortnite fracture event leak

Super

Someone out there let me know, wouldn’t the paint slow down the break at all? Even the tiniest amount?

To answer your question about speed, there is at least 1 plane that goes above mach 4.2.
