  • You gotta get Destin on this. Do a collab with Smarter Every Day. He'll figure it out.

  • The force is distributed over the glass ball and then concentrates once again on the opposite side. Sea it like a circular wave going around and colliding on the other side. That's why

  • How comes all the guns he used are from pubg

  • So the damage on the opposite side of the glass from the impact point appears to be caused by an effect we call "spalling" (different from what a lot of people call spalling). Basically because the pistol bullets are quite short, you set up a situation where you have a massive tension spike almost at the back surface, essentially pulling the layers of glass at the back off. It would also explain why the rifle round didnt seem to have this effect as the rifle round is slightly longer, meaning the tension spike would be deeper into the sphere where it couldnt do as much damage. This effect was actually a problem for WW1 tank crews as their armour had similar issues against small arms fire. My bona fides on this are a PhD in Shock Physics that makes me think this is whats happening.

  • The big glass ball is so confuing

  • Dude wear a mask! The shit that's making you sneeze are tiny glass shards you are breathing in!

  • SMARTER EVERY DAY !!!!!

  • Sphere ripples through surface, thats why you see a crack in the other side, it is where ripples reunite and nothing in the middle. Edited: example video ischats.info/fun/ZKyaqWSof6GhpXg/v-deo

  • My theory of why it cracks or breaks a little at the back when you actually shoot the front is because of the percussion of the bullet hitting the glass being so powerful

  • get slowmo guys to film it close up!!! really want to see the energy go trough and do the chipping on the back of the ball.

  • Think Mercury vs. impacter. If I'm remembering right there is a famous picture of planet Mercury shows the same phenomenon. Huge crater on one side and shockwaves rippling on the other, it almost blew the planet apart. Your bullet is the giant asteroid and the ball is Mercury.

  • the thumbnail says america so much

  • Matt:I feel allergenic. Matt's nose: mmmmmmhhhhhhh I love me some glass

  • Her: he’s probably out cheating. Him:

  • matt please notice meee pleasee bro

  • 5:32 Matt: *Straight At My Tiny Ball*

  • So imagine a fish tank in the aquarium but thinner

  • at exactly 6.00 there is a demonic dog in the background please check not lying

  • The shock wave is traveling through the glass as it follows the structure of the sphere, meaning it goes outwards, until the narrowing of the other side focuses the force on the other side.

  • this was in my recommended? i dont even know who this is but the most troubling thing is how did youtube know i have a 50cal

  • We all knew the answer but yet we clicked anyways....

  • That last gun absolutely made the ball shit

  • It's probably the actual impact hitting transferring all of the energy to the back and cracking again once the force hits the back.

  • I like how he lost $0 in the begging skit XD

  • The chipping of the opposite sid is because of energy transfers throughout the entire ball and is released oppisitely 9f the original force which is stated in newtons laws of and equal and opposite, and it isn't the same exact hole on the front because some energy is dissipated into other types of energy

  • Spallation

  • Dang that’s fire 3:13

  • This would be cool on Slow-mo guys. At least, they've done glass shattering and the speed of it but, I wonder how the shattering directly affects the rear of the sphere.

  • SHOCKWAVE !

  • Imagine what would a 50 cal do to a human skull 😱

  • No

  • I really need help finding/buying an ar15 in .223/5.56 nato or a .308 ar15 but I can’t find them anywhere on line and idk where I can find one. Can you please help me out

  • Its the Shockwave of the impact having constructive interference. As it ripples around both sides thats the point at the back the Shockwave collides. The part that cracks or breaks is where impurities in the glass are.

  • the force of the bullet is proportional to the speed it was fired. if the force is bigger it will spread aside from the ball, but if it's lower the force wil travel trough the ball without harming it and ripping off a piece from the back

  • when the bullet hut the glass ball it transmits all the force it had when fired in every direction. the force goes trough the ball until it reaches the end. there it escapes and tear a little part of the ball from the back.

  • No.

  • Its simply because the force of impact is transfered through the glass atom but because the force goes out from the back which made it looks like it cracked

  • Kinetic Energy = Reason, Also, I am glad to see you managed to have fun this 2021

  • heres an idea why not film the impact slomo ? also why shoot 3 bullets with the magnum instead of saving it for the big guns

  • You're sneezing glass hahaha, can't be too good on the lungs either I would assume....

  • I’m no genius but I believe that what is happening is the energy or impact from the bullet is carrying on throughout the ball and is breaking the other side I guess it’s almost like kinetic energy

  • the crack on the other side is like a newtons cradle the energy from the bullet goes through the glass and spreads out at the back cracking it

  • worst intro

  • A sound wave is created at the point of impact. It travels through the sphere along the surface. It doesn't interfere (collide with itself) until it reaches the opposite side. Then it constructively interferes, creating a massive spike of energy that has no place to go but outward.

  • What happened with the glass: Glass is not a solid, at least not completely. It's sort-of between solid and liquid. What caused the cracking on the other side of the glass, is quite literally, that the glass was rippling like water when it was struck, and that cracked it.

  • its because glass is actually a liquid even if it feels solid

  • well if you got 200 dollars to spend for a bullet vest, just wear a massive glass ball

  • Energy transfer

  • See it like this. You at least made 90 bucks.

  • no it cant

  • The force of the gun like pushes the air and cracks the thing in the back ...I think

  • plane glas shatters into small pieces because it's safety glass ... if it where not safty glass it would also just shatter into chunks... how can you not know this..

  • It’s the vibration causing the back to rupture the same way as the bullet hole.

  • You need a giant prince Ruperts drop! One of THE strongest glass structures known to man. Until you break the tail and they shatter into a million pieces.

  • just a guess but i think what's going on is the bullet hits and the force is spread out in a wave across the surface and meets up on the opposing side which all the energy gets compressed into a single point. kinda like dropping a pebble into a pond.

  • Why am I just NOW!!! finding this channel?!!!?

  • smooth glass on the inside is cause its not a solid glass ball, it started cooling down before it was that large, so when the ball completely cooled, the inside shaped first. It's like welding. So its glass wrapped around glass, rather than being one cohesive blob of it.

  • I'm pretty sure the bullet, on contact, transfers it's energy to the ball in the form of a wave which after the energy disperses, leaves the ripples; Glass is flexible, so think of it almost like a wave on a lake or pond. The hole(s) on the back are the product of a small amount of energy making it to the opposite side of the ball, exiting quickly, leaving that small crack or hole

  • Its called bible perxushion is what's happening from shock wave

  • Wonder if he was breathing glass dust making him sneeze? He spent a week in the hospital and didn't say anything.

  • The cracks on the back are coming from it being a sphere. The energy travels around the sphere and meets on the opposite side cracking it. If you want more detail you can look up wave propagation in a sphere.

  • Him:Oh this is completely smooth, but this looks like it could cut me “touches without thinking twice”

  • Don't know if it had been posted or not before..there are 32k comments atm. The back blowing out is because the shockwaves all spread out from the initial point of contact, bounce around in the sphere, probably as much as we can polish one to be...the end result of all that physics is that all of the waves will reconverge at a given point at the same time. Less perfect the sphere..less perfect a circular blowout from the back

  • I know Matt has shot precious metals like gold bars but has he ever shot diamond? I’m sure he hasn’t considering how much money it would cost to have a big enough diamond to shoot but it would be really interesting to see what different bullets do to a big hunk of diamond

  • Whoa! This intro skit took a real dark turn! Was not expecting him to murder himself!

  • Someone call Destin from Smarter Every day STAT!

  • You still alive?

  • The vibrations go through the glass until it hits the other side

  • We need some slow-mos on these shots!

  • quiet now turkey news extraordinary nine alcohol examination post explanation empty invent.

  • the spalling on the back is caused by the shock of the impact travelling through the sphere and getting re-concentrated on the opposite side of the impact

  • You want to know what is happening to the big ball? Get a high speed camera and you will see!

  • yo why is it tiny 5:33

  • The sneezing was from atomized glass particles. I hope you got all that shit out. Thanks for inhaling it for our entertainment.

  • Mat choose to spend the 100$ on ammo

  • I'm pretty sure the reason why it is shattering in the back of the ball is that the vibrations travelling through the ball and putting more stress on the back end. Think of it as a wripling effect

  • 3:00 LIKE. OUR. EYEBALLS. RIGHT? :)

  • Me if I don't get another 100 hundred dollars guy ok I'm done boomboomboom falls down

  • 14:05 DAM THAT WAS A LOUD CHLING

  • Ayyyyy I think I know why it’s cracking at the back there is a pressure wave from the bullet going through the glass so it’s cracking

  • “That looks like it could cut me.” -touches anyway.

  • Yeah a 50 BMG explosive armor piercing round is going to blast through almost everything.

  • Only in america.

  • Most of the energy is adsorbed in front and goes into fracturing the glass. A small amount of energy goes into shockwaves which is transmitted to the backside.

  • the intro tho

  • Its breaking in the back because of the shock wave of the guns and because its not breaking the mid because it is

  • 10:32 when my dad farts and burps The windows near him:

  • Harmione leaving divination be like

  • the crack on the back I believe, would be called an outpact

  • who is on the camera?

  • Hi Matt my name is Matt I’m a massive fan of your I’ve subbed to all your channels and your Spotify account this might sound weird but it’s because I’ve got autism so I don’t know how to properly word it but I was wondering if you could test a custom lightsaber to see what it stops and this is the bit that is going to sound weird and I’ll send you my address and if you could I would be so happy if you could send it to me I LOVE YOU AND ILL SEE YOU NEXT TIME #DONTTELLMERE

  • Are they twins?

  • I'm guessing the reason the back gets cracked and not the center is the same way newton balls work to put it simply.

  • you need a slow mo cam

  • .50 will split it!, sorry disintegrate it! Hope it isn't glass particles in your nose!

  • Joining the Military soon. Training to be a welder. And Under water welder. Would you care if I stopped by to shoot some guns with you in the future?

  • No

  • It cracked on the back from the 45acp, because that's where the Shockwave converged. Like a ripple in water except because it's spherical the ripples came back together at the exact opposite side from where they started. When they merged the shock wave then became forced in a small area. Thus your Crack 😅 was very interesting to see. By the way, yes glass IS classified as a liquid.

    • No and No. Glass is not a liquid. Glass is an amorphous solid.

  • Inertia. The momentum of the bullet gets put into the tiny spot it hits and spread throughout the sphere. Since it was going practically perfectly straight it caused it to take the extra momentum to the back of the sphere causing chipping in the back.

  • The energy travels around the entire ball in a wave and then meets on the opposite side and cracks it.
