The current world record is .10 second splits (give or take -- it was 5 shots over .57 seconds). In that case, each bullet would travel 40 meters before the next shot went off. (This is ignoring the fact that the shooter wasn't using 9mm, and I'm actually unsure of what caliber he was using, but presumably it was a slower load, so it'll be in the same ballpark as 9mm)

Yep that’s how it works. As sound is longitudinal it relies on particles vibrating each other to produce a wave. Seeing as air particles are ‘free’ and there’s lots of space between them, the speed of sound in air is much slower than a liquid or solid, where the particles are always touching. Seeing as they’re always touching it allows for much faster ‘transfer of vibration’. Something that makes a lot of sense but you’d never think of it had someone not told you :D Hope the crude explanation was helpful

The initial movement of the glass when cracking far exceeds the speed of sound in air, so it would create a sonic boom. However, the amount of movement is so slight that it probably wouldn't create a pressure wave big enough to see on film. Any sort of sonic boom is a compression event, meaning the sound it makes is not the same as a sound wave...you're hearing and feeling a shockwave rather than sound propagation. That's likely why you're able to feel it from a distance, because shockwaves act differently than sound waves.

@@musiciseverything120 In a visual representation, a soundwave is generally a nice curvy sinusoidal shape, whereas a shockwave is a square or sawtooth shape. Soundwaves are a gradual increase and reduction in pressure whereas a shockwave is a violent and abrupt overpressure event all compressed into a very short burst. The sonic boom of aircraft is basically all the sound that the aircraft makes in flight concentrated into a single pressure wave, so rather than it being spread out over a period of time, it happens all at once. That's why a near supersonic jet won't blow windows out but the same jet flying just a little over the speed of sound will.

It's always super cool that glass breaks internally completely before collapsing.

I've fired many firearms in my life, it's so cool to see The Slow Mo Guys shoot them in slow mo.

I like the way the glass stays together for a short time after it is broken ... like done in cartoons for comedic effect.

The cartridge you'd want to use to compare speed is a .22-284, it's a way overbored cartridge, and loaded with a 60gr bullet they'll hit 4400fps (3,000mph). Lighter bullets will approach and sometimes exceed 5,000fps (3,400mph), so you'd be able to beat the glass in a race with the right load. Also, the lightweight bullets (40gr or so) have a tendency to rip themselves apart soon after departing the barrel, which is why heavier match bullets are the usual load for this cartridge...only a handful of heavily jacketed bullets will handle the speed and centrifugal forces coming out of a 1:7 twist barrel. Having a bullet disintegrate midair would be an awesome thing to capture on camera, but it's an unpredictable event that might happen right out of the barrel, 50 yards out, on impact with a gnat, or not at all. I guess you could score the bullet before loading to make it a little more predictable.

Dear slow mo guys: please listen to this guy! It would be so cool to see a bullet rip itself apart! However: a few tweaks to his request. 1: it might be hard for you to get a 22-284. So get a 22-250 as they are everywhere. Hornady makes a 35 grain ntx bullet in the “superformance” line that will achieve 4450 fps. It still won’t be as fast as glass, but much closer. Second: if you CAN use custom bullet loads, then please do what he is suggesting as either of these calibers (with custom loads) can achieve speeds high enough to catch this glass, AND have the potential to rip itself apart! That would be so cool to see in slow motion!! Also: food for thought there are ample rumors that a .17 Fireball in R&D had several test rounds that were vaporizing as soon as it left the muzzle. (Or at least tearing itself apart.) Please, please try this! Listen to this guy, he knows what he’s talking about, I just added to it. Thanks for the fun content!

Agreed. Seeing a bullet over rev and tear itself apart in slow motion would be really cool. I can easily accomplish this with my 22 creedmoor and light weight bullets. The problem of course would be figuring out when the catastrophic failure will happen.

I'm from Texas, only a few hours away from these guys, and I happen to have two guns available in .22-284. I don't mind bringing them out and loading up some real barrel burners if they're interested. The .17 Rem, .204 Ruger, .220 Swift, and .22-250 can all be loaded to ridiculous velocities, but the .22-284 has them all beat by a good margin. In its introduction, Bob Hutton was getting 6,585fps from a 15gr iron projo and 50 grains of 4227, the iron was necessary to keep the projo intact at those speeds and with the lower density of iron they could keep the weight down while maintaining a reasonable aerodynamic shape. Titanium might be a good replacement candidate for iron if one wanted to recreate those velocities today. It's by no means a practical cartridge, but if you're wanting to launch extremely low BC bullets that look like miniaturized ICBM's at mach 5, or take a small bullet and send it to legitimately hypersonic speeds, it's probably the most practical cartridge you can find.

I think it would be cool to revisit this with maybe 5.56 and 7.62x51. Also if you can, the 220 swift is one of the fastest bullets and thus has the best chance to keep up to the glass.

Tempered glass. It's TEMPERED glass. Car side windows, and plate glass doors are made of this.

Guys, this was an outstanding video. GREAT JOB on the whole thing.

A bullet is not a wave, but in physics mechanical waves propagate faster in an object like glass than air. You could have answered the question even without making a video about it but guys, YOU'RE AMAZING AND I LOVE WHAT YOU DO❤

I think the closest rounds you will come close to the speed of the glass shattering are: .17 Remington (or possibly .17 Remington Fireball), .223 Winchester Super Short Magnum aka WSSM, .220 Swift, .224 Weatherby Magnum, .22-250 Remington, and .204 Ruger... most of which are very uncommon rifle rounds. I think the .204 Ruger may have the best chance here based on reloading data in my book.

Id love to see y’all get a steel 55 gallon drum and fill it with a bit water while on a fire. Then out the lid on and take it off the fire and spray it with cold water so it collapses. I’ve wondering if it’s buckled in faster than glass breaking

For those interested, the timing of the glass breaking starts when the bullet is 77% of the way across the span.

Hearing them talk about the “different” speeds of Mach 1 about how sound moves faster through a solid than through air just absolutely melts my brain

Well, after converting for fps, your glass is breaking at about 4700 ft/s. There are actually a few sub .22 cal cartridges with factory loads which exceed 4000ft/s, and a couple that are pushing 4500ft/s... I think it would be interesting to see roughly equivalent bullet to glass velocities.

If I’m ever making a movie I’m getting these guys to shoot the action. They’ve got this perspective on things you don’t usually think about

It should be noted that the bullet velocity would vary by the type of bullet and gun it is fired from. For example, most rifles will fire the bullet at speeds of about 2-3 times faster than most pistol rounds can. Not that it would be able to beat the glass. The speed of the glass shattering would probably still beat most rifles, but it would be a much closer match. The only handheld weapon that I know of that could probably beat the glass shatter is the Steyr IWS 2000. It's an anti-materiel rifle that fires a subcaliber APFSDS round that travels at speeds of about 1500 m/s. The 5.56×56mmSR (.220 Swift) rifle round might come close at 1300 m/s, but not quite enough to beat the glass.

Now i really want to know what happens when a big fat slow 9 mm hits a spinning tire with lots of tread on it at like a grillion fps.
