How Fast Can We Spin Bulletproof Glass Before it Explodes?

[@theCodyReeder]

Tapering the material to be thinner at the edges can allow higher speeds. For instance, the wheels of a supersonic car have a lens-shaped cross-section. As a bonus that should allow for jetting more towards the center of the wheel thereby providing leverage that allows the wheel's edge to spin faster than the speed of the water.

[@seabass1111]

First reply in 18 minutes?!

[@Klaevin]

yes, moment of inertia. maybe have two cylinders of different diameters, so they can shoot the water at the small, thick one, while a thin, large diameter part is spinning with more angular velocity WAIT, ARE YOU CODY??

[@WaterjetChannel]

Interesting… we’ll have to try that on our next spinning wheel endeavor

[@The-One-and-Only100]

Hi Cody

[@ThePoliticalBulldog]

More Cody videos please. Chickenhole base vid?

[@BaowSchmeow]

The problem with the bullet proof glass wheel was you had the waterjet hitting in between the layers of the bullet proof glass so it was just separating/destroying the weakest layers causing it to blow apart faster than probably if it was designed the other way (instead of looking at the face of the bullet proof glass having a hole in it, it should have been the side of the bullet proof glass having a hole in it).

[@pallasproserpina4118]

bulletproof glass is designed to be strong from the front, not from the side

[@ryanrandolph6193]

could probably get around that by encasing the glass in resin as well as having resin between the layers. Even so, it likely would slightly perform better than what was done in this video since it's similar to the broken glass in resin wheel.

[@Meisto95]

It would delaminate and be destroyed faster, thats my guess

[@Melipolus]

Or if it had been spun normally from the center rather than using outside force and friction causing erosion to begin with

[@VengeanceYT21]

Bullet proof glass isn’t resistant to centrifugal force, only kinetic energy from the front/back.

Bro, after a single incident like these, the hydraulic press channel decided to build a concrete bunker around the test area. And you, things keep exploding and flying in every direction and you just chuckle and move on. You are certainly playing with the odds.

[@jonskillings1258]

He's like .1% of the area something flying could hit, so the odds are in his favor... until they suddenly, violently, aren't. He shouldn't even need a chamber, surely all the electronics can be moved further back or operated remotely. It doesn't look like anything needs to be constantly held down in order to operate like a Sawstop, but it's possible there's some regulations since it's a shop, they have to follow OSHA rules or the owner will lose their license or something. If not, it's just foolish.

[@theledman]

[@wesleyboyer6654]

The pressure of the sand and glass might have deformed the silicone. Had some issues with that before, if you try these again try some heavy duty molding silicone. i use dragon skin silicone for my molds.

[@JohnDlugosz]

Also, use a soft silicone coating on the original part and then cast that in a hard material (often plaster-soaked bandages).

[@ChristinaAtkinson-xc6jw]

The mold was made circular, but had no support to keep it that way. The material being cast pushed out on the mold asymmetrically. Make the mold in a box and keep the box for later when you do the casting. This will help it keep its shape.

[@tridentpower6954]

When trying to make bulletproof glass again, may I suggest setting up all your layers, get the air bubbles out of the resin, and then using a spong brush to brush the resin on each layer as you stack it, you will have to leave it where you make it but it will be a big block of BP glass you can cut stuff out of it maybe

[@RyzToZaction]

Thanks, I am special. Sometimes its nice to be reminded of such. Cheers.

6:13 - what's with Nate in the background? how did he get there?

[@python2400]

Is there a way to rig up a shaft thats strong enough to be spun by the water jet, maybe with like steel or titanium fins on it, so that the wheel of random material can just spin and not be affected by the jet itself?

[@supdawg2173]

Just use a pressured water pipe as the axle, and have have two off center holes on opposite sides. Optionally, extend those away from the center of rotation with curved pipes to get even faster speeds. The water comes out at the opposite angle of rotation at all times at high speed. It will keep ramping up until the considerable force of the extremely high pressure water is equal to the force of air resistance on the extenders, plus minimal air resistance from the axle rotating, plus the friction of bearings.

[@TEAMGFYM]

[@colbster12302]

You should get a rear sprocket from a bicycle and hit each gear 1 at a time. You'd probably get world record land speed with the gear reduction to the imaginary wheels. free banger of a video right there.

[@TheAruruu]

There's a company in Woodlands Texas called ChampionX. They make Diamondback 3D printer nozzles out of a substance called "Bort", or polycrystaline diamond. Unlike regular diamonds which are incredibly hard, but brittle and easily smashed, borts are incredibly hard and very durable (those nozzles are basically invincible). You should reach out to them and see how big of a bort they're able to make, and if they could make a bort skateboard wheel. I can pretty much guarantee the algorithm would love a title like, "Spinning a solid diamond skateboard wheel at hypersonic speeds", and a thumbnail with "REAL DIAMOND" in it...

[@witherd5733]

You're more of an expert with materials than I am, so I'd love your input. If I were to use resin to mold clear beyblade parts, do you think the resin you used in this video would be impact resistant enough to survive beyblade battles?

[@LordDragox412]

Not if you spin the Beyblades at 6k RPM.

[@JohnDlugosz]

Don't use plain resin. Make it *composite* by using, say, fiberglass. You can buy shreds (as opposed to sheets) that are meant for molding like that.

[@williamdowling7718]

A very interesting video! Since childhood, I have also been interested in things that can be called extreme. For example, will a match light up and how will it burn at a pressure of 10 or 100 atmospheres? How will the electric motor behave with a smooth increase in frequency from the standard 50 Hertz to 100, 200....400 hertz? What will happen to a bullet flying through a cutting jet of water?

you might want to do something about how you attach the wheel. The bolt is turning. see 6:39 for example. Also inhaling glass dust is no joke.

[@thefatrat5240]

Interestingly glass dust isn't nearly as bad as quartz dust. crystalline materials hold an edge on the atomic scale much better than amorphous materials.

Honestly it makes sense, if the plexiglass wasn't really contributing at all then the glass+resin wheel and the glass+plexi+resin wheel should perform about the same

[@shreds08]

“Break a speed record” *Proceeds to spin wheels at thousands of rpm*

[@andrewevenson2657]

I don't know if you have tried this yet, but I imagine the rotation of the objects causes tensile stress in the material until the stress gets so high it rips itself apart. So, why not try a tungsten wheel, as tungsten has the highest tensile strength of any natural metal. I tried looking up alloys with greater tensile strength, but all I could find was people saying they exist but not saying what they are? The highest tensile strength material is graphene which obviously you will not be able to make a wheel out of, but it's tensile strength is about 130 times greater than tungsten even. I would dare to guess the tungsten wheel would not explode, unless you modified it so that it's just a tungsten ring around a filler material, in which case you could make the ring thinner and thinner till the tensile stress is greater than the tensile strength. In fact, that could be a cool project all together, gradually increasing the thickness of the tungsten until you find out the tipping point between exploding and retaining it's shape. Or maybe the solid tungsten wheel would just explode idk.

[@willb.383]

The mold is fine. You just needed to make the mold a shell so that the soft silicone didn’t deform while curing.

[@blargcoster]

It amazes me you still haven't upgraded the shield to protect the waterjet.

[@ChrisS22699]

Could you test big bearings, just the bearings on their own, and different types like roller bearings and ball bearings, to see how fast they go before they fail.

[@hershy1594]

Bulletproof glass wasn't that strong because the water jet hit the sides, and it can take a lot more compressive force than shear force. You could get it to work a lot better if you cut progressively smaller circles to make the wheel, but the wheel would only be as thick as the sheet of glass you cut it from. The sand didn't care because its one solid object. Great video btw!

[@maxworx1411]

[@brianm.4243]

Want a true test to see how fast something can spin without the extra variable of the waterjet touching and damaging the item? Build a finned wheel onto the shaft that the water jet hits and spins and let the item of test to sit attached to that shaft. The finned wheel should be a strong enough material to resist coming apart.

for those people who wants to know the speed of the spinning wheels in kmph or mph The speed of the 3d printed wheel is about: 274 kmph or 170 mph the speed of the sand wheel is about : 1357 kmph or 843 mph the speed of the glass shard wheel is about: 788 kmph or 489 mph And the speed of the bullet proof glass wheel is about: 777 kmph or 482 mph Keep it in mind that these values are not completely accurate. Like this videos thumbnail Mach3 is 2301 mph Mach2 is 1534 mph And Mach1 is 767 mph

The Mach 3 in the thumbnail is for the water leaving the waterjet. But I’d be lying if I said I didn’t think some people would think it’s for the wheel lol
