that's why good helmets aren't made to be strong they are made to crush on impact, absorbing as much of the energy as possible. Also why you should replace a hemet after a fall, or really even after dropping it really (for proper motorbike helmets)

I used to work in a factory that created polyurethane foam parts for the auto industry (Cup-holders, armrests, etc). The chemicals that Line-x uses are the same as the ones that we used to make auto parts. This stuff has some amazing properties but as all of you saw it is an incredibly messy process. It's kind of crazy to think that with the right ratio of Iso and Poly and the right pressure, you can create this stuff. However, these chemicals are an environmental disaster. Isocyanate reacts with water instantly and once it is exposed it crystallizes instantly and it is almost impossible to separate once it has made contact. Getting this stuff in your eyes, mouth, nose is horrible, you can go blind from it and it can be lethal. Plus the waste for any process involving these two chemicals is considerable. I'm surprised that the EPA hasn't shut that factory down. It was insane.
I agree, I also spent time in similar factories. Too bad there are no economical replacements. Maybe 3D printing in 20 years. All that PU has the deadly combo that capitalism loves. Its cheaper to make, faster to make, easier to make and stronger than most any other material in existence and it’s highly tunable. The difference in foam/plastic type you can get just by varying temp/pressure/ratio can produce a nearly infinite variety of products at practically no extra cost to the manufacturer. All the major processing tools and materials are the same. Like growing 100 different kinds of fruit from the same tree. Speaking of environmental impact, synthesizing the raw materials at plants like ones on chemical row in Louisiana. Eek, scary to see what it does to people and the environment. It’s really in everything. But it’s like what are people gonna start stuffing the seats of their Honda’s with dead leaves and coil springs?

Haha. Last year was like what, a single frame? With the drums? Keep up the amazing videos Derek! Can you make a video on Zeno's paradoxes, if you haven't already? Pretty sure you haven't.
I noticed how thick the coating on that watermelon was. It wasn't a thin coat like on the paper, it was about an inch thick. Wouldn't pretty much any other common rubbery material have achieved the same result with so much coating? I think this experiment is confounded. The Line-X stuff sure is cool, but to really give a decent idea of exactly how durable it is, you'll need to find the minimum necessary coating thickness and compare it to that of other materials which may be put to the same use. It kind of makes this entire video fun but pointless. =/
That's the point of a demonstration experiment. Make it as thick as possible so that nothing will go wrong. ;) That being said, there are not many elastic compounds that you can spray onto a watermelon. Many of the stronger ones need an oven to cure and most others a very large amount of time.
I wanna say this is basically an infomercial, but that's actually some really cool stuff. Its properties and the method of application make it super versatile.
GOOD GOD dont ever use a miter saw like that. For one it is an object that could easily catch the blade. Second, it is not steady and stable by any means. This is from someone that cut the tip of their thumb off btw. People... for real listen to this. Dont cut catchable bendy or brittle stuff, or anything that cant be positively held still on a miter saw. PVC... bad idea. Anything fabric-like... bad idea. Anything rubbery... bad idea. Something ball shaped.... bad idea.
cut my entire thumb off from wrist to index finger about 7 years ago using unstable spinning blade technology. so yea i kinda have to agree with that warning. they did re-attatch it. works...kinda good.
@erni muja If you cut off enough they can do the tiny surgery like that and yes put everything together to hopefully get function back. Mine was a bit of only the tip part of my thumb and the Dr said the blood vessels were too small to reattach, so now I just have a shorter thumb with crappy sensitivity on one hand.
@@giampaolomannucci8281 Not sure I would claim that is better. I just cut off like a quarter inch and have a funny feeling tip and weird nail. When people cut more from the base and reattach it I think they usually dont get great function or feeling back.
What a fantastic visual demonstration of the incredible surface bond strength of Line-X! If it can survive the drop test followed by the repeated axe strikes, it's fair to say that it will make an extremely durable truck bed liner or other protective coating. Thank you for this informative, scientific, educational and entertaining video, which I greatly enjoyed!

Cool video, but there is some bad Materials science in this video. The process you describe at around 3:33 is polymerisation, whereas this reaction is far more likely to be a crosslinking. i.e. Rather than short chains getting longer, the curing process is pre-existing long chains getting interconnected at multiple positions. This changes the mechanical properties of the mixture from a viscous liquid, where with enough force, the chains are able to slide over each-other, to something elastic, where a small amount of deformation is possible with the straightening of the tangled chains, but is limited by the interlocking groups preventing any sliding, essentially any elastic. The straightening of the interlocked molecules is a very energy intensive process, which means that any deformation of the polymer absorbs a lot of energy, and then this energy is released again when the polymers re-curl (entering into a higher entropy state). This is what allows the ball to bounce, and not break.
The only good thing that happened to me in this quarantine is to found you.... because I love learning for my cooler impression in front of my friends 😎
@Dan ny I don't work with lineX but this is most likely. With spraypaint it helps to invert the can and pull the trigger to clear the nozzle between uses. Even then, I bet the mixing chamber is semi-disposable. You get buildup over time.
In short. Air. You have 3 feeds and a heating element in the hose. The two components and an air line, when you trigger off air is pushed through the gun clearing the nozzle. This stuff only mixes right at the gun tip and cleaning the gun by hand isn't too hard but it does involve using a nasty solvent like naphtha (sp?) a sharp knife and some patience. Nothing is disposable and this stuff is nothing like paint.
Archaeologists in Norway have discovered dozens of arrows-some dating back 6,000 years-melting out of a 60-acre ice patch in the county’s high mountains. Read the article here: on.natgeo.com/37bTrDj
Nathan Trone the traction would be pretty poor. tyres wear down because they grip the road and that causes wear. the harder the tyres, the less wear but also the less grip. if this was able to withstand wear, it'd likely be unsafe to drive on
I think it'll be like a tiny hole would form, and them all that explosive stuff would shoot out at really high pressure and it would look like a blown up balloon that you released without tying
Pretty similar process to polyurethane foam roofing, it also has an a and b side that mixes together to make foam pretty much sprays through the same kind of gun they used in the video.
The two components have separate nozzles within the front air nozzle(replaceable) the two nozzles are angled towards each other with the two streams colliding within the airflow, so while the two mix within the airflow of the gun they dont actually mix within the gun structure itself
It could be that the air continues for a fraction of a second after flow of the two chemicals is stopped from entering the mixing chamber. That final bit of air would flush the remains of the mixed chemicals before they begin to harden.
The coating is flexible so your car should still crumble like usual when you crash, as long as the coating isn't way too thick at least, I'm more interested in whether the coating can prevent denting and scratches.
That's pysical nonsense. kinetic energy isn't transferred to the people because it's more robust. We know from newtons first law that people inside the car would only get their own kinectic energy (1/2*m*v^2 m= the person v= speed of the car/speed of the person) because of Inertia. What you mean is that with a robust car the collision is more rapid than the collision without a robust car. (and can push the robust car back so it creates backwards velocity that increases damage (elastic shock)) That's why the people get more damage. But I also think not so robust cars will kill more people because of inner space deformation.
This would be a horrifying weapon if say an army used it as a weapon, as it would do the following: A: Stick to your enemies and quickly harden B: Heat up very quickly and spray out hot C: Immobilise them and make the unit essentially dead D: 3rd degree burns would be the most common cause of gruesome death E: the bodies would be difficult to dispose of humanely So... if anyone reading this comment is a commander or general or something high up in the military of ANY country, please no.
Is it wrong that now I wonder how you could Line-X a cat? They're already great at landing on their feet from high falls, imagine the heights that thing could survive!
Legion of Weirdos they would die from suffocation, but if not that after that intense of a fall all of their body contents would be mashed and mixed around
Get a TPU (thermoplastic Polyurethane) case. It is a very similar material made using the same reaction and has very similar properties. This polyurea is not much of a new invention it is a basic concept in undergraduate polymer classes.
They just throw old Nokia phones into giant crushers that need to be replaced every 3 days and BAM, Nokia powder just waiting to be rebranded as Linex.
We can use this linex for army vests, inner ceramic coating, 2 layers of linex covered thick industrial strength kevlar, it could survive ak and other shots.
Typically we have up to 4 ceramic plates in our vests, made of boron carbide, they are rated for small arms fire. An AK model rifle and several other types of rifles fire 7.62 mm rounds, this is currently what the ceramic plates are rated for. I'd be curious to know if spraying the plates themselves in Line X could increase the amount of attacks the plate can take, as they can only take a few rounds before they stop working. Or you could drop it on the ground. *ceramic plates will break if dropped, even the smallest invisible hairline fracture can mean the difference between the plates doing their job, or your job coming to an end.*
I used to work with this stuff and tried coating everything under the sun. One of the best results was a drum kit. But also made some indestructible skateboard decks and vandalism-proof public bathroom stalls. Super amazing stuff, there's a million uses for it people probably haven't considered but it is probably not a nice product for the environment. I imagine nature wouldn't break it down for many thousands of years.
@@salaciousBastard so if I was being pedantic (and I am) you would paint it with antifouling paint to reduce drag and also fuel costs if it's a power driven vessel!
@@kiesesoza Since we're being pedantic, LINE-X website says they offer smooth coatings that reduce aerodynamic drag on vehicles and increase gas mileage by 10%, plus out perform paint in wear and tear. Are boats different?
Flynn Asher this whole video is an ad. If you think the makers of linex have nothing to do with this you're out of your mind. Linex is not new or special. Two part flexible coatings have been around for decades, linex in particular for at least 20 years. I really like veritasium, or did at least. I don't know what's going on with dirk from veritablium, if he is hurting for money and needs to do these kinds of videos, but at the very best this video comes off as off putting. I'd feel the same way if it was a video about the brand new Ford f150, and the thumbnail had "unstoppable" in great big capital letters.
haha, sorry you feel this way. For the record Line-X did not sponsor or ask to be involved with the video in any way. My friends at How Ridiculous thought I might like to explain the science behind their experiment and I agreed it was cool.
If I may, this product was made as a protective coating/ liner. Which ended up being used as a truck bed liner. Small FYI, this product actually goes on smooth. Texturing is achieved by misting it in the air and allowing it to settle on a freshly applied coating. Furthermore, by itself, it is not bulletproof, some type of kevlar or similar product is needed. Assuming mils are below .5-1" thickness. It can be used in bomb blast mitigation, which can be achieved by coating both sides of a masonry wall.
People actually do that, it's particularly popular on old jeeps and 4x4's in general. It wouldn't make your car mechanically tougher, but it would make it scratch resistant. Basically you'd never have to worry about a shopping cart hitting your car again...
x''(t)=g x'(t)=gt + C x(t)=(1/2)gt² + Ct + D with g=9.81m/s² and t=3.01s the speed at the beginning of the fall is C=0m/s and the starting height is D=0m if you put the x-axis straight down from the top. x'(3.01s)=29.53m/s=106.3km/h x(3.01s)=44.44m However if we resolve the falling time according to the height of 45m we get a different result. (1/2)gt²=45m t²=(45/4.905)s² => t=3.029s with that we get x'(3.029s)=29.72m/s=106.97km/h And all this is not even considering the air resistance which would slow the melon down even further. Either the tower is higher than 45m or the specified speed of over 107km/h is false. But when we take the measurement of 148ft or 45.11m we get: (1/2)gt²=45.11m t²=(45.11/4.905)s² => t=3.033s x'(3,033s)=29.75m/s=107.11km/h In summary: the measurements given here are kinda vague and should not be relied on.

That's why for making helmets, strength of the material is the parameter instead of its elasticity.

It kind of makes this entire video fun but pointless. =/
That's the point of a demonstration experiment. Make it as thick as possible so that nothing will go wrong. ;)
That being said, there are not many elastic compounds that you can spray onto a watermelon. Many of the stronger ones need an oven to cure and most others a very large amount of time.

GOOD GOD dont ever use a miter saw like that.
For one it is an object that could easily catch the blade. Second, it is not steady and stable by any means.
This is from someone that cut the tip of their thumb off btw.
People... for real listen to this. Dont cut catchable bendy or brittle stuff, or anything that cant be positively held still on a miter saw. PVC... bad idea. Anything fabric-like... bad idea. Anything rubbery... bad idea. Something ball shaped.... bad idea.
cut my entire thumb off from wrist to index finger about 7 years ago using unstable spinning blade technology. so yea i kinda have to agree with that warning. they did re-attatch it. works...kinda good.
@erni muja
If you cut off enough they can do the tiny surgery like that and yes put everything together to hopefully get function back.
Mine was a bit of only the tip part of my thumb and the Dr said the blood vessels were too small to reattach, so now I just have a shorter thumb with crappy sensitivity on one hand.
@@blahblahsen1142 Can you show it in any way? Maybe make a video? It's fascinating that you got your thumb back and it still works. I'm glad for you!
@@Jasoninee So it's better to cut the whole thing off and not just the tip? Amazing.
@@giampaolomannucci8281
Not sure I would claim that is better. I just cut off like a quarter inch and have a funny feeling tip and weird nail. When people cut more from the base and reattach it I think they usually dont get great function or feeling back.

What a fantastic visual demonstration of the incredible surface bond strength of Line-X!
If it can survive the drop test followed by the repeated axe strikes, it's fair to say that it will make an extremely durable truck bed liner or other protective coating.
Thank you for this informative, scientific, educational and entertaining video, which I greatly enjoyed!
spray it on helium balloon and leave it in open area , will it burst in space ?
probably not. The tensile strength is 6000psi, much greater than the 14.7psi of the atmosphere
saurabh atram also it won't lift up to space, only few km high, untill air becomes as dense as helium
Veritasium, I was thinking of attaching a Go pro camera below the coated balloon of helium and leave it in open area, will it be able capture images after reaching high enough?
+Peter Rabitt i thought it would smell like tar
Peter Rabitt helium can make it through almost anything. baloons have pores. everything has pores if youre helium.

You should watch "Cloudy with a Chance of Meatballs", the answers in that film. :)
Cool video, but there is some bad Materials science in this video.
The process you describe at around 3:33 is polymerisation, whereas this reaction is far more likely to be a crosslinking. i.e. Rather than short chains getting longer, the curing process is pre-existing long chains getting interconnected at multiple positions.
This changes the mechanical properties of the mixture from a viscous liquid, where with enough force, the chains are able to slide over each-other, to something elastic, where a small amount of deformation is possible with the straightening of the tangled chains, but is limited by the interlocking groups preventing any sliding, essentially any elastic.
The straightening of the interlocked molecules is a very energy intensive process, which means that any deformation of the polymer absorbs a lot of energy, and then this energy is released again when the polymers re-curl (entering into a higher entropy state). This is what allows the ball to bounce, and not break.
The only good thing that happened to me in this quarantine is to found you.... because I love learning

4:45 my only question is what stops the gun from clogging also, I'd like to make armor out of that.
@Dan ny I don't work with lineX but this is most likely. With spraypaint it helps to invert the can and pull the trigger to clear the nozzle between uses.
Even then, I bet the mixing chamber is semi-disposable. You get buildup over time.
It's called Rhino-Liner
In short. Air. You have 3 feeds and a heating element in the hose. The two components and an air line, when you trigger off air is pushed through the gun clearing the nozzle. This stuff only mixes right at the gun tip and cleaning the gun by hand isn't too hard but it does involve using a nasty solvent like naphtha (sp?) a sharp knife and some patience. Nothing is disposable and this stuff is nothing like paint.

I wonder if this stuff would be good for tires? I mean, where are they getting the resources from? is it from oil?
Nathan Trone the traction would be pretty poor. tyres wear down because they grip the road and that causes wear. the harder the tyres, the less wear but also the less grip. if this was able to withstand wear, it'd likely be unsafe to drive on
It would be really interesting if they tested inflating it. Although I seems like a really hard substance to mold.
Just put a coating on the inside of the tire, anti-puncture tires!
If it can stop a bullet, then there's a pretty good chance it will stop a nail
Trancecend it doesnt stop bullets, it coats a metal plate and catches the bullet fragments
sir the job you are doing is priceless .. incredible thankyou so much
line-x an explosive and try to explode it
that sounds awesome
I think it'll be like a tiny hole would form, and them all that explosive stuff would shoot out at really high pressure and it would look like a blown up balloon that you released without tying
Mythbusters or another discovery show did that and showed it's explosion proof.
Pretty similar process to polyurethane foam roofing, it also has an a and b side that mixes together to make foam pretty much sprays through the same kind of gun they used in the video.

I also made a magical substance by some two ingredients I call A and B 😂
-Cave Johnson
How does that gun not get instantly clogged up with polyurea?
R.B. Has to dry.
R.B. the two components mix outside the gun in the airstream
Good question 🤔
The two components have separate nozzles within the front air nozzle(replaceable) the two nozzles are angled towards each other with the two streams colliding within the airflow, so while the two mix within the airflow of the gun they dont actually mix within the gun structure itself
It could be that the air continues for a fraction of a second after flow of the two chemicals is stopped from entering the mixing chamber. That final bit of air would flush the remains of the mixed chemicals before they begin to harden.

Molten Science hey I like your channel.
thanks +micheal lee :) and +fucduck u could be right on that lol
The coating is flexible so your car should still crumble like usual when you crash, as long as the coating isn't way too thick at least, I'm more interested in whether the coating can prevent denting and scratches.
Probably would not prevent denting, unless you have concave parts on the exterior, as the material doesn't seem very hard
That's pysical nonsense. kinetic energy isn't transferred to the people because it's more robust. We know from newtons first law that people inside the car would only get their own kinectic energy (1/2*m*v^2
m= the person v= speed of the car/speed of the person) because of Inertia. What you mean is that with a robust car the collision is more rapid than the collision without a robust car. (and can push the robust car back so it creates backwards velocity that increases damage (elastic shock)) That's why the people get more damage. But I also think not so robust cars will kill more people because of inner space deformation.
it would be cool to see something like this in like a Web shooter
Michael Roberts Jr omg yes!....never thought of that .....you might be onto something here
Not if you want to scald an enemy in the process. But I can see where you are going with the idea.
Fighting bad guys with Linex. Just imagine you pulled out your Linex can instead of your Mace in the midst of combat.
This would be a horrifying weapon if say an army used it as a weapon, as it would do the following:
A: Stick to your enemies and quickly harden
B: Heat up very quickly and spray out hot
C: Immobilise them and make the unit essentially dead
D: 3rd degree burns would be the most common cause of gruesome death
E: the bodies would be difficult to dispose of humanely
So... if anyone reading this comment is a commander or general or something high up in the military of ANY country, please no.
CoacoBudder pretty sure that would be against somekind of rule of law.

Legion of Weirdos I mean, the watermelon broke quite a bit on the inside so the cat would still be so very very dead.
Cats can already survive terminal velocity. I don’t think they need the help.

lol polyurea made me think of polyuria, the condition of urinating excessively.
I need this on my phone
Richard Z cover it with a nokia shell. actually linex is made up of nokia molecules instead of the poly-urea molecules as said in the videos.
Get a TPU (thermoplastic Polyurethane) case. It is a very similar material made using the same reaction and has very similar properties. This polyurea is not much of a new invention it is a basic concept in undergraduate polymer classes.
They just throw old Nokia phones into giant crushers that need to be replaced every 3 days and BAM, Nokia powder just waiting to be rebranded as Linex.
+Juggernath Nokia's Executive Powder. It's got a million and one uses...
We can use this linex for army vests, inner ceramic coating, 2 layers of linex covered thick industrial strength kevlar, it could survive ak and other shots.
Typically we have up to 4 ceramic plates in our vests, made of boron carbide, they are rated for small arms fire. An AK model rifle and several other types of rifles fire 7.62 mm rounds, this is currently what the ceramic plates are rated for. I'd be curious to know if spraying the plates themselves in Line X could increase the amount of attacks the plate can take, as they can only take a few rounds before they stop working. Or you could drop it on the ground. *ceramic plates will break if dropped, even the smallest invisible hairline fracture can mean the difference between the plates doing their job, or your job coming to an end.*
That stuff could be a great restraining tool...
Allen Zhao yeah but you'd burn them live.
I don't think he meant to use it to spray people. probably to form the materials to a restraining tool, maybe something like a cable tie.
I used to work with this stuff and tried coating everything under the sun. One of the best results was a drum kit. But also made some indestructible skateboard decks and vandalism-proof public bathroom stalls.
Super amazing stuff, there's a million uses for it people probably haven't considered but it is probably not a nice product for the environment. I imagine nature wouldn't break it down for many thousands of years.
Pretty sure it's vulnerable to cracking,ripping or stretching?!.
Every boat on the planet should be coated with this before it's painted.
Except the paint would probably crack too easily since this coating seems pretty flexible
Hmm. Why would you need to paint it when it's coated with this? Color? I wonder could you dye this instead?
@@salaciousBastard so if I was being pedantic (and I am) you would paint it with antifouling paint to reduce drag and also fuel costs if it's a power driven vessel!
@@kiesesoza Since we're being pedantic, LINE-X website says they offer smooth coatings that reduce aerodynamic drag on vehicles and increase gas mileage by 10%, plus out perform paint in wear and tear. Are boats different?

quosmo1 Wow, where did you get a sense of humour like that?

Flynn Asher this whole video is an ad. If you think the makers of linex have nothing to do with this you're out of your mind. Linex is not new or special. Two part flexible coatings have been around for decades, linex in particular for at least 20 years. I really like veritasium, or did at least. I don't know what's going on with dirk from veritablium, if he is hurting for money and needs to do these kinds of videos, but at the very best this video comes off as off putting. I'd feel the same way if it was a video about the brand new Ford f150, and the thumbnail had "unstoppable" in great big capital letters.
haha, sorry you feel this way. For the record Line-X did not sponsor or ask to be involved with the video in any way. My friends at How Ridiculous thought I might like to explain the science behind their experiment and I agreed it was cool.

Applying it on Motorcycle fairings .seems like a good idea
If I may, this product was made as a protective coating/ liner. Which ended up being used as a truck bed liner. Small FYI, this product actually goes on smooth. Texturing is achieved by misting it in the air and allowing it to settle on a freshly applied coating.
Furthermore, by itself, it is not bulletproof, some type of kevlar or similar product is needed. Assuming mils are below .5-1" thickness.
It can be used in bomb blast mitigation, which can be achieved by coating both sides of a masonry wall.
Good example of why the skull can be intact but the brain inside is mush. Inertia is not your friend.

NolePtr 🌠🌈🌈🌈🌈🌟THE MORE YOU KNOW🎶🎵🎶🎵
zingadooda yeah boiiiii
x''(t)=g
x'(t)=gt + C
x(t)=(1/2)gt² + Ct + D
with g=9.81m/s² and t=3.01s
the speed at the beginning of the fall is C=0m/s and the starting height is D=0m if you put the x-axis straight down from the top.
x'(3.01s)=29.53m/s=106.3km/h
x(3.01s)=44.44m
However if we resolve the falling time according to the height of 45m we get a different result.
(1/2)gt²=45m
t²=(45/4.905)s²
=> t=3.029s
with that we get
x'(3.029s)=29.72m/s=106.97km/h
And all this is not even considering the air resistance which would slow the melon down even further.
Either the tower is higher than 45m or the specified speed of over 107km/h is false. But when we take the measurement of 148ft or 45.11m we get:
(1/2)gt²=45.11m
t²=(45.11/4.905)s²
=> t=3.033s
x'(3,033s)=29.75m/s=107.11km/h
In summary: the measurements given here are kinda vague and should not be relied on.
The specific speed is unimportant, the point is that it is going fast
