Vsauce3 Ok, I have two problems between both your videos, first in your video (not this one) the paint can was full, and in the movie it was maybe about 1/3 full. Then in this video (all though it doesn't really matter) a snowball breaks apart on impact, a softball doesn't. Sorry to nit pick like that, but I'm a bit of a perfectionist. I love both your videos, and Mark's videos!!
Physics teacher explaining momentum in school: - 5 lessons - 15 book pages - 234 slides me: still don't get it. Mark explaining momentum: - 10 seconds me: oh that's how it works!
every adult in my life - “Electronics are bad for you, they teach you nothing” me - “I BET YOU DONT KNOW WHAT HAPPENS WHEN YOU GET SNOWBALL CHUCKED AT YOU GOING 95MPH”!!!!
@@YoMama9021 greg has a point. The snowball would be imparting more of its kinetic energy than the softball. When the softball bounces off, it's retaining energy rather than transferring it to the body. Also the pillow absorbed a lot of the energy of the impact, reducing the force actually applied to jake so we really don't know what would actually happen if a snowball were to hit someone at 95 mph. Too many variables were changed in this experiment for it to be considered a good analogue for the movie scene
thats not true boss. almost all of the energy is released on impact nd if you have ever lived anywhere with snow as a kid you will know that they are not perfect and fluffy. they are hard as ice
@@destroyeryt-iz9dj momentum is always conserved even if collision is in elastic but the velocity of both his body and the bsll depends on how elastic the collision is
Mark might've won, actually. The punks didn't have any protective gear besides winter jackets. Jake had a pillow and a vest on him, so if he did get hit without them, he probably would've stumbled over in pain.
Second test isn't accurate, the softball is much more structurally sound than a snowball, most of the energy would be dispersed into the snowball and it would break apart.
It also depends on the composition of the snowball. If the snowball has partially melted and refrozen, it can be almost as hard as a rock (snow mixed with ice is surprisingly tough). On the other extreme, snowballs made from dry, nigh-unpackable snow will poof apart in midair without even reaching their target. While we can assume the snowballs in Elf are somewhere in between, the effect of their impact would vary greatly depending on just where they fall on that spectrum.
In the softball representation, all of that padding is absorbing a lot of the energy and doing that means he was less likely to fall than if he hadn't had any padding. - Penny 10
@@KeziahMeg agreed it seems to me like they are treating it like a single item and not a mechanical system that would loose alot of its kinetic energy pushing the indivituad snowflakes appart upon impact, although i think this might be hard to test because imparting enough energy to a snowball to make it travel at 95MPH would likely shred it
@@champignyluthier I know your not trying to act smart, you are smart. But for some really weird reason your smartness is annoying me. I'm really sorry.
But the softball is not even equatable to the snowball, even at reduced speed. On impact the snow balls break up, dissipating some of their kinetic energy.
Jedi Master 150 but the snowballs broke and lost all of their energy on impact. The softball continued going and all of its force was spent continually going forward
One thing to note regarding the snowballs is that Buddy didn’t just throw one. With the rate of fire he had, he might've been able to knock the bullies over. And interestingly the way they tested the blowtorch is actually how they filmed it, except with a mannequin and antique oil-fired blowtorch, plus reflective glass.

I feel like the snowball test was innacurate because the softball doesnt break apart/become deforemed.. if it were really a snowball, most of the kinetic energy would be spent deforming/breaking apart the snowball
Sure, but softball players don't wear more protection than coats, and although they weigh more than 8 year old children, they take 65-85 mph shots all the time. You don't see them flying back off their feet. Falling due to pain maybe, but not actually being moved by the force of the pitch, that's just crazy. Even when a shot rifles off their head they often just get back up and take their base.
Actually when it breaks apart it pushes more force onto the person not less, as before the ball flew backwards needing force to go backwards, input energy = output. Also there is a lot more absorbing the impact, we can do the maths, momentum is m*V so mass of a person 80kg and mass of a snow ball is... for a 8cm snowball, 0.2kg. The speed of the snow ball being 153km/h maths is simple the total momentum for the ball is 8.5 kilogram meters per second. Now assuming all the energy is used to push you back momentum/mass = speed, You'll be pushed back at 0.4 km/h. It doesn't take too much to make a person not go 0.4 km/h, I could work out forces but I'd have to assume a bunch of things like how long it takes for the impact to happen. But just from this we can say there isn't enough momentum to push you back properly. 153km/h is fast but you are only moving 200 grams, so once to move it to 80kg or 80,000 grams its force is a lot lower.
Jonathan Mayer most if not all the energy would dissipate on impact due to the density of frozen water, and surface tension holding it together being relatively weak.
But they tested it in a way where he did have safety and they knew that so they put that into consideration they weren't talking about a fresh hit from 60mph softball WITHOUT protective gear... if you can't understand this with your little minds i dont know what to say...
I can cerify that a modern, commercially available Daisy Red Rider BB gun can fire a BB with adequate velocity to cause a ricochet to come back and hit you hard ehough to sting, but you also have to be ridiculously close to the target.
Yes but...you don't need to be a scientist to know a snowball moving at 95mph won't knock you over. Pitchers throw baseballs that hard and the guys that get hit anywhere other than the head just wince. He kinda flubbed that one.
With the Elf Test, there's a bit to be desired, as the kids were only wearing snow coats in the movies, which are padded, but not as much as catcher's pads or the pillow underneath. Mark should've won.
The softball is also a false equivalency. You can't use momentum to find an equivalent mass/speed because it changes the total energy. While momentum can tell the relationship between colliding objects, it is only mv, while the total kinetic energy of the ball is actually 1/2mv^2. Since the velocity has exponential growth, the much higher speed snowball will have more energy than the slower softball if you equated the two using momentum.
Christopher wootton Exactly why instead of throwing it at 95mph they throw it at 60mph. You can calculate the dispersion of energy by figuring out the young modulus of the ball and softball, and adjusting the velocity to imitate the energy at impact with two distinct materials :)
But they used padding and a pillow. Their theory with using a softball because they have the same momentum was good, but the pillow would change things. The whole purpose of protective gear is to disperse the force over time--as the ball hits a softer material, the collision takes more time which makes the maximum force (which would be what would push you backward) smaller in order that the area under the curve (the momentum) be the same. This protects you from injury, which is good, but would lessen the effect they want to test. With a less soft area to hit (a person instead of a pillow and padding), the time of collision would be shorter, making the maximum force higher, and the effect of being hit therefore also higher. Yes, a snowball would break apart, but this would change things much less than having extra padding would. www.google.ca/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&ved=0ahUKEwir3oKtvPvQAhVN-GMKHb-uC-QQjRwIBw&url=http%3A%2F%2Fwww.bbc.co.uk%2Feducation%2Fguides%2Fz9499j6%2Frevision%2F5&psig=AFQjCNFoa0-Ax2iPSmeXn-OjQ2BXO0e6FA&ust=1482072460629865 for a force time graph. The coloured one is with padding, the dotted one without. (Ignore the numbers I just found it on google.)
Sean Lastname Uhm, he said "half a million people lose their eyes to an injury every year." You're just using what he said out of context. You can lose your eye to something other than an injury..
actualy dispersion of snowball would make the hid less severe since when you get hit by softball every bit of energy goes to your body, if snowball hits ya end disperses a lot of energy will go to you in same point but a significant amount of energy would go in dispersion of the snowball. also i think they did simulate that somewhat with the pillow
The amount of energy determines how much damage the snowball could do - and the fact that some of the energy gets dissipated by destroying the snowball does reduce the amount of energy available to damage the target. However, this test was specifically about whether the snowball would knock you backwards, and that's determined by the momentum transferred, not the energy. The net result is similar, however. A ball which bounces off the target elasticly can transfer nearly twice as much momentum to the target as one that just stops after hitting the target without bouncing.
5:40 He's wearing an incredible amount of padding, and, as I saw in another comment, the snowball would break on impact, and, realistically, would actually break apart even earlier.
Round two isn't completely accurate. seeing as that pillow and padding is absorbing a lot of that momentum before impact. you would need a dummy that isn't padded and is about the equivalent weight of a human to be hit to get an accurate result.
Wouldn't the second test also be inaccurate because the kinetic energy of the softballs and snowballs are different? While momentum is equal to mass times velocity, kinetic energy is equal to one half of mass times velocity squared - double the speed, halve the mass, and you have the same momentum but twice as much kinetic energy.
However due to the padding the impulse is different and impulse is what imparts momentum to an object, by increasing the impact time...which is the point of padding in general....you reduce the force and this will impact the results of the experiment for number two.
you also have to account that the kids were unprepared for the attack, and they were kids, their height and weight could make a lot of difference from the experiment
Delta Phoenix I think that's incorrect because the snowballs kinetic energy will partly be spent to accelerate the snowball fragments, rather than transferring all of the momentum to the target
As always, I love your videos. I was hoping for a more "realistic" test with the Red Rider, as Ralphie was yards away when he got hit by the ricochet. I'm guessing the bb wouldn't have bounced that far in return.
5:42 Well, with the padded suit, Jake would not have moved back so far as if he'd just gotten hit "directly" --- i.e., unprotected --- with the ball; a "solid" hit is more forceful than a shock-absorbing one.
Actually, I think the padded suit and pillow would absorb so little of the energy from the ball, that the only measurable thing from the impact would be how far he was pushed back. The pillow and padded suit might make him get pushed further back, considering more of the energy could go into pushing him back instead of breaking his ribs, his spine, and causing other damage.
Mark the snow ball is smaller and more dense than with a mineral and resource causing the snowball to break when a softball is concrete rock leather string and loose air pumped rubber causing the softball not to break and if you listen all of newton's laws you realize a snowball breaking on you cuts down the speed because a spherical snowball has diameter 10cm and density0.75g/cm3 meaning the effect would be less
People get hit with baseballs at 95 mph all the time. They sometimes fall over from the pain, but not from the impact. And if the snowball dissipated most of it's energy by breaking up on impact, it probably wouldn't hurt that much.
I know I’m late, but a bit of dampness would have protected from maybe .7 seconds of the flame. A soaked and dripping hat might have done 2-3. All in all, not too good. You’ve still got serious damage.
If you get hit by a snow ball at 95 miles per hour it would probably feel like a full on loaded truck ramming you while playing Pokémon go in the middle of a highway
It’s all hypothetical I don’t see any reason to point out the unrealistic aspects of a fictional movie than to stir up drama But I do agree that the science is awesome and I basically only watch his videos too lol so brownie points
Wow VSauce3 is way more awkward than I thought he would be Also like, a snowball would fall apart so that's not a fair test at all. And styrofoam melts, should've bought a slab of meat to put under the chicken skin and then measure the temperature of the meat and skin.
They were testing the initial impact so the test was fair. And the test was if it burn through to the bb. If you haven’t noticed, styrofoam isn’t the best replacement for a head in any way shape or form
5:40 you have an issue with this one, the kids that were being hit were a lot younger than a grown man and thus weaker making it very possible that the kids could have fallen down
@@uremqpogprvu1975 Only true if that object lacks the force to CONTINUE its travel through your body. In that case it staying together or not matters greatly lol.
I think the ricochet will penetrate: Hard target, hard BB, so the bounce won't take a lot of energy. I noticed nobody volunteered to take a BB shot from a gun poked through the pet door though......
Only once it has been heated. Most styrofoam is covered in flame retardant substances due to how flammable it is. That’s not to say that it doesn’t burn quickly but it’s probably the closest they could get.
I feel like the snowball one wasn't tested correctly considering the body armor and the pillow that was between Jake and the softball maybe instead of actually hitting him with the ball you could have measured the force of impact that the ball has then tested it but yanking Jake backwards with a rope or something using the same amount of force
Mark, that Kobra kai shirt is awesome and I think that the snowball would have maybe have been broken on impact, and with jake having a pillow covering his stomach, all the punks had were just thick coats, so I think you won that round.

Mark Rober Hey Mark, could you quickly explain how you calculated the speed of the snowballs based on the frames?
The problem with that second experiment is that they where more protection than a coat and also they where men not 8 year old children
Vinidu Geevaratne yeah but the problem also is that they use a softball that has no dispersion and that could reduce a lot of the pushback
Sure, but softball players don't wear more protection than coats, and although they weigh more than 8 year old children, they take 65-85 mph shots all the time. You don't see them flying back off their feet. Falling due to pain maybe, but not actually being moved by the force of the pitch, that's just crazy. Even when a shot rifles off their head they often just get back up and take their base.
Yes, the pillow is a lot softer and can absorb more of the impact than a coat would have.
Also, a snowball is quite variable. Are we talking an ice ball or something that will fall apart on impact?
Actually when it breaks apart it pushes more force onto the person not less, as before the ball flew backwards needing force to go backwards, input energy = output. Also there is a lot more absorbing the impact, we can do the maths, momentum is m*V so mass of a person 80kg and mass of a snow ball is... for a 8cm snowball, 0.2kg. The speed of the snow ball being 153km/h maths is simple the total momentum for the ball is 8.5 kilogram meters per second. Now assuming all the energy is used to push you back momentum/mass = speed, You'll be pushed back at 0.4 km/h. It doesn't take too much to make a person not go 0.4 km/h, I could work out forces but I'd have to assume a bunch of things like how long it takes for the impact to happen. But just from this we can say there isn't enough momentum to push you back properly. 153km/h is fast but you are only moving 200 grams, so once to move it to 80kg or 80,000 grams its force is a lot lower.
The snowball one is not accurate because a snowball would explode which would make the energy dissipate a lot more
Grant Embrey if in fact it was packed hard enough and it melted a bit I think it could stay together.
My thoughts exactly. The explosion of the snow ball would dissipate a lot of energy.
Jonathan Mayer most if not all the energy would dissipate on impact due to the density of frozen water, and surface tension holding it together being relatively weak.
But they tested it in a way where he did have safety and they knew that so they put that into consideration they weren't talking about a fresh hit from 60mph softball WITHOUT protective gear... if you can't understand this with your little minds i dont know what to say...

Yes but...you don't need to be a scientist to know a snowball moving at 95mph won't knock you over. Pitchers throw baseballs that hard and the guys that get hit anywhere other than the head just wince. He kinda flubbed that one.
ROBER
Me too
because he used to be a NASA worker
Vsause: how are we going to get to get a snowball going 95 mph?
Me: put it on kingda-ka
Mark Rober is by far one of the most coolest scientists ever.
Yes hecis
3:43 dang mark you must really want that leg lamp
Lol yeah
Who wouldn't want that
Since he has a cobra Kai shirt on, he’s more than a hero, he’s a legend.
True dat
That is all I thought lol.
Yessss bro

4:48 CRAP I THINK I GOT THAT WRONG ON MY PHYSICS EXAM YESTERDAY.
same
He said it wrong, its mass x velocity rather than weight x velocity
DarudeSandstorm either way I think I failed 😂
Oof
@@cynthiapitman4580 yes
With the Elf Test, there's a bit to be desired, as the kids were only wearing snow coats in the movies, which are padded, but not as much as catcher's pads or the pillow underneath. Mark should've won.
The softball is also a false equivalency. You can't use momentum to find an equivalent mass/speed because it changes the total energy. While momentum can tell the relationship between colliding objects, it is only mv, while the total kinetic energy of the ball is actually 1/2mv^2. Since the velocity has exponential growth, the much higher speed snowball will have more energy than the slower softball if you equated the two using momentum.
jake roper
mark rober
hmmmmm
they are almost brothers
Chill Animations I was thinking the same thing
Chill Animations they do look/sound very similar lol
Chill Animations,almosttttttttttttttt
That makes no sense
They look similar too
A snowball comes apart much more easily than a softball. I think it would break apart and disperse the energy.
my thoughts exactly
Pretty much, but if a softball that doesn't break up doesn't have much of an impact, a snowball will have even less impact.
Christopher wootton Exactly why instead of throwing it at 95mph they throw it at 60mph. You can calculate the dispersion of energy by figuring out the young modulus of the ball and softball, and adjusting the velocity to imitate the energy at impact with two distinct materials :)
But they used padding and a pillow. Their theory with using a softball because they have the same momentum was good, but the pillow would change things. The whole purpose of protective gear is to disperse the force over time--as the ball hits a softer material, the collision takes more time which makes the maximum force (which would be what would push you backward) smaller in order that the area under the curve (the momentum) be the same. This protects you from injury, which is good, but would lessen the effect they want to test. With a less soft area to hit (a person instead of a pillow and padding), the time of collision would be shorter, making the maximum force higher, and the effect of being hit therefore also higher. Yes, a snowball would break apart, but this would change things much less than having extra padding would. www.google.ca/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&ved=0ahUKEwir3oKtvPvQAhVN-GMKHb-uC-QQjRwIBw&url=http%3A%2F%2Fwww.bbc.co.uk%2Feducation%2Fguides%2Fz9499j6%2Frevision%2F5&psig=AFQjCNFoa0-Ax2iPSmeXn-OjQ2BXO0e6FA&ust=1482072460629865 for a force time graph. The coloured one is with padding, the dotted one without. (Ignore the numbers I just found it on google.)
"People lose their eye sight due to eye injuries." Well obviously.
Jan Celin oh thx
Sean Lastname Uhm, he said "half a million people lose their eyes to an injury every year." You're just using what he said out of context. You can lose your eye to something other than an injury..
I can’t believe this video was 6 years ago! It’s one of my favorites!
Same
Ikr
the second test is false since a snowball doesn't stay intact when it hits something it spreads out most of the energy
actualy dispersion of snowball would make the hid less severe since when you get hit by softball every bit of energy goes to your body, if snowball hits ya end disperses a lot of energy will go to you in same point but a significant amount of energy would go in dispersion of the snowball. also i think they did simulate that somewhat with the pillow
The amount of energy determines how much damage the snowball could do - and the fact that some of the energy gets dissipated by destroying the snowball does reduce the amount of energy available to damage the target.
However, this test was specifically about whether the snowball would knock you backwards, and that's determined by the momentum transferred, not the energy.
The net result is similar, however. A ball which bounces off the target elasticly can transfer nearly twice as much momentum to the target as one that just stops after hitting the target without bouncing.
What are y’all saying
We’re did u get that information from huh Wikipedia
And I’m talking about who sent the main message
Mark: explains how a 60mph softball has the same momentum as a 95mph snowball
Jake: yeah, I know
Wouldn't a lot of the snowballs energy be dissipated since it likely wouldn't stay in tact, unlike the softball
JOTARO!
The video is AMAZING. Two of the best RUclipsrs in a Christmas collaboration! GREAT

Your videos are so awesome they teach me so much every day
Such a genius video idea, gosh.
John Hill hi
Ooh, John Hill the skateboarder. What a pleasant surprise finding you in the comments section.
hey i watch ur vids
Didn't expect to see you here
Sup John
Mark is so smart when he talks i lose brain cells trying to think about what he just said
...
IKR
I’m doing 1 million calculations a second they’re all w r o n g
“Oh” You try to think of that word?
Jake: But how are we going to get a softball going 95mph?
Get a wii sports pitcher. I got 97 mph with them
Probably Matt if you want the best results
5:40
He's wearing an incredible amount of padding, and, as I saw in another comment, the snowball would break on impact, and, realistically, would actually break apart even earlier.
Round two isn't completely accurate. seeing as that pillow and padding is absorbing a lot of that momentum before impact. you would need a dummy that isn't padded and is about the equivalent weight of a human to be hit to get an accurate result.
Braxia Kiessling it would only absorb shock not the pressure of impact causing the knock back
Wouldn't the second test also be inaccurate because the kinetic energy of the softballs and snowballs are different? While momentum is equal to mass times velocity, kinetic energy is equal to one half of mass times velocity squared - double the speed, halve the mass, and you have the same momentum but twice as much kinetic energy.
True
However due to the padding the impulse is different and impulse is what imparts momentum to an object, by increasing the impact time...which is the point of padding in general....you reduce the force and this will impact the results of the experiment for number two.
you also have to account that the kids were unprepared for the attack, and they were kids, their height and weight could make a lot of difference from the experiment
When it shows the dented plate it all so shows how many times you missed.
StashWax ha 😆!!
i feel like this is an allignment of 2 galaxys perfectly lined up to create...

Mark I have been watching your videos for 5years you are my favorite RUclipsr
Yeah but if you weren't wearing all that stuff you would've been knocked down
Mad?
Veci no. I'm just commenting
Frozo 1290 probably not if people don’t get knocked down by a 95 mph fastball in baseball I doubt a snowball could knock someone to the ground
They used it to make it more accurate since the snowball would break on impact.
@@sann980 *65 mph, for the baseball. 95 for the snowball
But snowballs also collape on impact so the softball would be harder then the snowball. And the impact also depends on how icy and hard the snow is
depends how you roll a snowball I roll mine up compacted up so it's more like a hard ice ball instead
jonathan oxlade But it will still fold into itself and explode, it just won't explode as bug
big
DanielBProductions but it would still give off the same amount of force.
Delta Phoenix I think that's incorrect because the snowballs kinetic energy will partly be spent to accelerate the snowball fragments, rather than transferring all of the momentum to the target
Mark Rober teaches me more in 8 minutes then my teacher could in 1 hour
the amount of time he actually cuts out and edits is way more then a hour, jus saying
I mean he's saying about how much he learned watching the video so he's still learning In 8 minutes even if Mark rober took hours making the video
*40 min
more than my teachers did in years tbh, not to mention getting my genuine interest lol (across multiple videos, not just this one.)
Don’t you mean 1 year
With the snowball/softball, you didnt take into account he was wearing protection, take the gear off i think he will move more
He had his eye shot out through a pair of glasses.
James Sawley uh no he just broke his glasses
It hit his cheek...
It hit his glasses
Only !
An icecle hit his glasses
And after the B.B. traveled all the way back to him.
You know what's impressive? The fact that they found a VHS of Elf. I didn't think that movie was that old!
wHAt'S a VhS?/?//?
Jake only stumbled a bit because he had the freaking equivalent of a kevlar suit. Those thugs in nothing but thin layers would do more than stumble.
100percent agree.
Not to mention Jake is a full grown adult, not a 12 year old
And a pillow
Yup 💯 straight-up facts
@@techngamin is true, so he’s stronger
As always, I love your videos. I was hoping for a more "realistic" test with the Red Rider, as Ralphie was yards away when he got hit by the ricochet. I'm guessing the bb wouldn't have bounced that far in return.
The softball would hurt much more because of the material because snow breaks apart on impact
It still hits.
That wast’t the point...
they used a pillow which spreads the impact
but the pillow cushend the blow absorbing the momentum making him move less
k thx that makes alota sense
but wouldn't the pillow help transfer the momentum over a greater area and less above the center of gravity making him stumble less?
Aipom Schnitzenwhitzle Not really because of the fact that a pillow is a (albeit kinda bad) shock absorber.
Aipom Schnitzenwhitzle But they're being thrown at kids standing on ice
Sherman Herritt KOREANS HAVE NO SOULS
0:00 - oh hi, Mark!
Sudden Cucumber a
5:42 Well, with the padded suit, Jake would not have moved back so far as if he'd just gotten hit "directly" --- i.e., unprotected --- with the ball; a "solid" hit is more forceful than a shock-absorbing one.
also he's not 12
and he is not on an icy bridge
@@fenceslamagic4739 Depends on the snowball.
100% i thought that too
They probably did it so Jake didn’t get the wind knocked out of him, or get some broken ribs
Actually, I think the padded suit and pillow would absorb so little of the energy from the ball, that the only measurable thing from the impact would be how far he was pushed back. The pillow and padded suit might make him get pushed further back, considering more of the energy could go into pushing him back instead of breaking his ribs, his spine, and causing other damage.
Mark the snow ball is smaller and more dense than with a mineral and resource causing the snowball to break when a softball is concrete rock leather string and loose air pumped rubber causing the softball not to break and if you listen all of newton's laws you realize a snowball breaking on you cuts down the speed because a spherical snowball has diameter 10cm and density0.75g/cm3 meaning the effect would be less
@luckster but you saw this meaning you where either late too or rewatching it having no point so why is that
We get it einstein
English please
EM Vlogs - Um so this person is talking pretty much the same as Mark, so why would you be so rude as to say that?
My mom : RUclips IS BAD FOR YOU
me: I watch this guy and all my teachers are dummber
MidnightXfire_fox {wildcraft} same
teachers are pushovers
You’re probably dumber with the way you spell “dumber” lmao
Agree
Oml yes
5:47 Mark is nice enough to give Jake a point, even though Jake was under a thick layer of armor.
No one:
Not a single soul:
Me: hehe *leg lamp*
I always called it the Sexy leg lamp-
Me too
I think the same
No me too
But be careful, it’s Fra-JEE-lay
wouldn't the pillow absorb some of the impact
Tru but at the same time I’m sure Jake likes his ribs regular and safe
he also had the chestplate on which would absorb some
People get hit with baseballs at 95 mph all the time. They sometimes fall over from the pain, but not from the impact. And if the snowball dissipated most of it's energy by breaking up on impact, it probably wouldn't hurt that much.
His hat could have been damp from the snow
yes but it could be vice versa, nobody actually knows
Edit: Yes, but it may have been the other way around, too, and was not damp
@@twisteddarkdays8150 Yeah, the snow could be damp from his hat.
@@JZStudiosonline I meant it might just aswell not been damp
@@twisteddarkdays8150 thats not what vice versa means
I know I’m late, but a bit of dampness would have protected from maybe .7 seconds of the flame. A soaked and dripping hat might have done 2-3. All in all, not too good. You’ve still got serious damage.
4:58 Yeah but softballs are harder/tougher I think :P
Mark:It wouldn’t hurt that much...
Me:..if he was wearing pitchers gear, and a pillow.
Macsen In Action and a board to protect the no no spot
If you get hit by a snow ball at 95 miles per hour it would probably feel like a full on loaded truck ramming you while playing Pokémon go in the middle of a highway

2:00, I was eating gum on this part so it makes it “way better.”
eating?
How have I gone my whole life without watching Vsause 3!? Vsause 3 is epic!
Buddy lived with ELVES. He. Was. TRAINED. Practically MAGIC. Thats just unrealistic. But the science is awesome. All I watch is your videos right now.
No one asked
@@robfilm1276 I didn’t need someone to ask to give compliments

Wow VSauce3 is way more awkward than I thought he would be
Also like, a snowball would fall apart so that's not a fair test at all. And styrofoam melts, should've bought a slab of meat to put under the chicken skin and then measure the temperature of the meat and skin.
Excuse me but did you go to Harvard?
Do the math Nicholas pipitone DO THE MATH
They were testing the initial impact so the test was fair. And the test was if it burn through to the bb. If you haven’t noticed, styrofoam isn’t the best replacement for a head in any way shape or form
5:40 you have an issue with this one, the kids that were being hit were a lot younger than a grown man and thus weaker making it very possible that the kids could have fallen down
lincoln Webster yeah but what kid would volunteer to be hit with a softball at 65 mph
Uhh
i want to say nerd but thats what i am
Plus a snowball would fall apart upon impact releasing less energy.
And he had a lot of protection
Idk why but him setting fire to the VHS of Home Alone is really unsettling for me
Teacher: teaching me math that I won’t use
Mark: teaching my science and making learning fun
Me: TEACHER WHY CANT YOU BE LIKE MARK
also your teacher showing up at school and barely getting payed to teach you valuable stuff but yes Mark makes it fun

Teacher: i cant be mark because i hate all of you!
Agreed same with my teacher
@@infirmn b r u h
But with the snowball one, a snowball will fall apart, while a softball will not.
Felplague it will after impact though.
It falling apart won’t transfer any more or less force
Falling apart is not a factor that comes into effect when you get hit
@@uremqpogprvu1975 Only true if that object lacks the force to CONTINUE its travel through your body. In that case it staying together or not matters greatly lol.
I think the ricochet will penetrate: Hard target, hard BB, so the bounce won't take a lot of energy. I noticed nobody volunteered to take a BB shot from a gun poked through the pet door though......
The torch one also being used on a styrofoam head is really not yelling at all. Styrofoam is extremely flammable/meltable.
Which is why they judged it based on the initial ski contact, and the 2 inch thing they put in his head
Well I think thats why they consulted burn experts. Cause they obviously couldnt test it on a human head.
Only once it has been heated. Most styrofoam is covered in flame retardant substances due to how flammable it is. That’s not to say that it doesn’t burn quickly but it’s probably the closest they could get.
I feel like the snowball one wasn't tested correctly considering the body armor and the pillow that was between Jake and the softball maybe instead of actually hitting him with the ball you could have measured the force of impact that the ball has then tested it but yanking Jake backwards with a rope or something using the same amount of force
I completely agree and I made a similar comment glad we are gonna be marks future bosses :)
From a Christmas story I think they meant he would be carrying it and accidentally press the trigger
Mark, that Kobra kai shirt is awesome and I think that the snowball would have maybe have been broken on impact, and with jake having a pillow covering his stomach, all the punks had were just thick coats, so I think you won that round.
The best duo on RUclips. If only every school had teachers like you
i don't need help i just need no chance of survival that's really not funny
lol so like, exactly one second after i was like "ew that is gross" the "told you" sign appeared and i lost it
mhm haha same
Jake only stumbled a bit because he had the freaking equivalent of a kevlar suit. Those thugs in nothing but thin layers would do more than stumble.
