Myth-testing Christmas movies with Science Experiments

Jake from Vsauce3 and I test scenes from Home Alone, Elf and A Christmas Story using only the Scientific Method... and some cow eyes.
JAKE'S VIDEO- • Could You Survive Home...

Thanks to Lowe's Home Improvement for letting me come out and use the set. Check out their behind the scenes: • Home Alone with Vsauce...
Summary:
We real life tested actual scenes from three Christmas classics in a replica of the Home Alone house:
1) A Christmas Story- Can you really shoot your eye out with a Red Ryder BB gun?
2) Elf- What happens if you actually get hit with a snowball at 95 mph?
3) Home Alone- What really happens if you put a blow torch on your head for 7 seconds?
The winner got to keep the awesome leg lamp and the loser had to wear Ralph's pink bunny suit

[@YoMama9021]

Greg Fulton it’s more about the initial impact then what happens after the snowball hits you. At least I think that was the point.

[@zachthompson9198]

@@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

[@davidcarlson399]

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.

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.

[@erickpoorbaugh6728]

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.

A snowball comes apart much more easily than a softball. I think it would break apart and disperse the energy.

[@pierre4004]

my thoughts exactly

[@rhettorical]

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.

[@themax1234521]

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 :)

[@asterismos5451]

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.)

[@grantembrey9953]

The snowball one is not accurate because a snowball would explode which would make the energy dissipate a lot more

[@audreyc4976]

Grant Embrey if in fact it was packed hard enough and it melted a bit I think it could stay together.

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.

[@silentcreeper7]

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.

[@debn1273]

Braxia Kiessling it would only absorb shock not the pressure of impact causing the knock back

[@nick012000]

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.

[@Carlos-if9ku]

True

[@brent13420]

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.

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

[@anfman1986]

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.

[@Skottel12]

Yes, the pillow is a lot softer and can absorb more of the impact than a coat would have.

[@toddkagler1467]

Also, a snowball is quite variable. Are we talking an ice ball or something that will fall apart on impact?

[@jamierice9211]

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.

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.

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

[@jonathanoxlade4252]

depends how you roll a snowball I roll mine up compacted up so it's more like a hard ice ball instead

[@delta4phoenix4]

DanielBProductions but it would still give off the same amount of force.

[@alextheophanis9271]

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

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.

[@myawelch6133]

They probably did it so Jake didn’t get the wind knocked out of him, or get some broken ribs

[@pamdrayer5648]

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.

[@TroutOfOrder]

4:40 Come on man, neither of the science guys really picked this up? Unlike softballs, snowballs break apart when they hit something. An object that weighs the same as a snowball that wouldn't break after throwing it is going to hit harder than a snowball.

[@DanUpshaw]

While I thought about this being an issue, too, there was something else I wondered following this. That is, a snow ball that can survive being hurdled at 95mph without disintegrating before it reaches its target, I would guess, needs to be packed pretty tightly. I hypothesize that a snowball packed tightly enough to withstand traveling at those speeds without breaking up will impact its target and transfer a significant amount of force before it disintegrates (if that disintegration was significant to the momentum transfer at all. Which, per Mark's response, it is not). Thus supporting Mark's hypothesis. The next questions I wold ask is how would this affect 10 year old boys as opposed to a 25year old man who has much more mass to resist the force being transferred, despite being on his heels. I would bet a baseball traveling at 95mph would knock a kid down. But that is a guess on a physics question, and I'm not a scientist (Mark is, and that is why his videos are great!). But my next question is, as a thought experiment*, since throwing an object at a person is not a simple physics question, i.e. we are dealing with more than just physical reactions and should account for human responses--pain, surprise, lack of preparedness, accompanying emotions, and so on--how would getting hit by such an object affect the recipient, and could all the additional human variables contribute to this person being thrown back farther than he or she would be were they expecting and preparing for it? At any rate, thanks, Mark, for giving us some cool things to think about! *"thought experiment" is a phrase I just learned from +Mark Rober, and I love it. It is a great way to explain thoughts I have daily!

[@dimihohota9942]

About the question that will you fall if a snowball traveling at 95 miles per hour would hit you. It depends, if the surface area of the snowball is big, you would fall, if the surface area of the snowball is small, you would not fall.

[@KhanggiTanka]

the second test is false since a snowball doesn't stay intact when it hits something it spreads out most of the energy

[@bigpod]

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

[@jameskuyper]

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.
