  • 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...
    THREADBANGER VIDEO (we also shot scene with Rob in the house... it's cool)- • Microwaving Christmas ...
    I made an unlisted vid to explain why the snowball test is valid since the physics is a bit counter intuitive and enough people brought it up: • Video

    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

      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!!

      @@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

    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.

    • @davidcarlson399
      @davidcarlson399 2 роки тому

      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.

      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.

      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 :)

      @asterismos5451 7 років тому +4

      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.)

      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.

      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.

    • @jamierice9211
      @jamierice9211 5 років тому +4

      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.

      @bigpod 4 роки тому +11

      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
      @jameskuyper 4 роки тому +4

      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.

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.
