Science Experiments for kids Center of Gravity with Dr. Shnitzel's Wacky Science

[Music] thank you [Music] welcome to the Dr schnitzel lab today we're going to be learning all about the science of center of gravity this is a little bit scary I have to balance it's not so easy you see gravity's pulling me to the right side and to the left side and I have to use my hands and my body to shift my weight to make sure I'm in the center yeah whoa whoa oh come along with me and let's go explore at the center of gravity over here I have a potato if I drop the potato it's gonna go up or down goes down that's gravity pulling it down there's The Birdhouse you notice the birdhouse has a stick in the middle why is the stick not on the side because then there would be too much weight the gravity would pull it to the side and fall down oh look what we have over here we have a Dr schnitzel purple pencil I love the color purple and we have over here a spoon it's balanced equally what happens if I take a little dime and I put it over here oh it's gonna be off balance it's gonna be too heavy on this side and gravity will pull it down let's see if it goes seeing when it comes to this GoPro it has three legs just like this telescope over here let me see if I can see somebody oh I see somebody doing a Mitzvah beautiful keep on doing those midsize if it only had one leg let's see what would happen it would fall and uh what if it had two legs or two let me try to balance it properly uh no it needs three legs look at this guy his name is look here's his hat his body his hands and I don't know he has one leg and he's holding two big buckets of uh water now if I put if I wanted to balance the top of the stick let's see do I put it on this side over here gonna be too heavy there what if I pull it put it on his head and it's going to make a boo-boo on his hat what if I do it in his stomach should we do it in the stomach his belly button now we have to find the center of gravity which is right here so take the pencil and we make a nice Circle this over here is exactly the center of gravity check this out look at that it's amazing it balances perfectly I have here a potato and I want to balance the potato on top of this little ruler mmm what do I do do I put it over here I gotta find the center of gravity just like that if it's too much to one side gonna fall if you could try it this way let's try this with an apple or anything oh almost too hard oh I almost did it well what happens if we help the Potato by giving it hands let me show you what I mean I have over here two forks we're going to take this fork and stick it in this side just like that then we're going to take the fork and we're gonna stick it in that side like this now oh watch what happens if we put it over here could it be it's like when you walk up on a tight rope if you're walking in a straight line you put out your hands and that helps us balance because as we're falling to one side gravity is pulling us down right we use the other hand to help us get back to the center of gravity watch this let's see if we can do that find the center okay let's see if we're gonna be able to bounce it oh look at that if I can go up I can go down I can go all the rest we have with us our helpers Ezra Ori and labe we're gonna have a race who can make big gigantic pyramids of cups but you have to make sure it does not fall over because watch if you put over here a couple like this okay then you put two over here then you go like this just like that and you have to keep on going higher and higher now if you don't have it balanced perfectly right center of balance and instead it's leaning over to over here a little bit then the weight shifts over here what's gonna happen it's gonna work see look at that that was don't fall on the floor it has to be exactly Center balance that whoever wins is getting a Coca-Cola classic who here likes the Coca-Cola classic yeah okay are you ready are you ready go [Music] I think I'm gonna win [Music] look at me I think I am winning everybody be careful make sure work with what you have work with what you have work with it go slowly look what I got over here I think I'm gonna win I think I'm gonna win I think I'm gonna win just like that I think I'm gonna win hey get back up over here they keep on falling hold on one second here goes [Music] whoa whoa whoa whoa whoa is he gonna do it is he gonna do it hey don't take him look at that wait who's the winner we're both hi an amazing but wait now you gotta quickly uh put them all the way all the way all the way how about we take this and we split it between all of us sounds like a good idea huh good job give yourself a big tap on the background job good job we're going to take this bill over here and I'm going to give each one of you a two dollar bill and a quarter you're gonna have to try to balance this exactly in the middle but what if it's just a little bit to the right or a little bit too much to the left what's gonna happen it's gonna fall who thinks they can do it oh well whoever wins is getting not one Laffy Taffy but the whole entire who here likes Lobby Davies yeah okay are you ready aren't you mark get set remember slow and steady go try try try you doing it anybody giving up yet is it possible is it possible who thinks it's possible who thinks it's not possible you giving up all right let me show you what to do you're gonna take your two dollar bill fold it exactly in half exactly like that and put it like this it should be able to stick stain just like that then you're going to take your quarter and very slowly put it exactly on the corner on the corner like this and hold it okay you got it now put your hand on the very top of the corner of the dollar just like this see watch what I'm doing and now slowly place your hands on the table and slowly try to balance it it's super hard it might take a few times to do it done good job blade oh mine fell I'm gonna try to do this again let's see who's gonna do it try to do it for as long as you can [Music] look at that oh look at that you know what I think Hmm what are we gonna do we're gonna split it again slave is the winner using center of gravity I can try to balance this on top of this you could use the hole you can try to balance it like this or like this or like that whatever it is whoever wins is the winner and they get to keep their entire soda bottle but you can't drink it up in one time you have to share it with your brothers and sisters okay Abbas Israel are you ready you guys ready okay here goes one two three go try to figure it out [Music] take your time do it slowly think about it think what we're doing center of gravity try to think no that's not gonna well I don't know if that's gonna work try it all right let me give you a hint it has to do with the bottom here okay but you guys are going too quick it's if you have to do it's very very slow oh look at that no way he got it amazing hold on let's see if you guys can do the same thing try to put yours in slowly without it yeah put it inside so don't move your hair back up a little bit so we don't knock it whoa this was awesome but the question is why is it balancing shouldn't it be going over to the side what do you think center of gravity you take this soda bottle and you divide it in half the exact centers right over here so as it's pulling this way but half the bottle that is on this side of the center so it's pulling this way so it's exactly equal and that's why it balances perfectly our next experiment with center of gravity is going to be to try to balance all these nails on top of this nail on your mark get set go try to do it okay you're trying that let's see remember you got to get them all on [Music] try try try how are you gonna get them all on think out of the box think out of the box [Music] to remember center of gravity center of gravity do you think they're gonna figure it out oh I like where you're going with that I like where you're going with that watch this you take one nail these are much bigger than those okay these over here are gigantic now we're gonna put one over here now we gotta put all of these on top over here right so watch we're gonna put this over here and we're gonna put this over here just watch what I'm doing I'll let you know when you can try to do that as well like that okay like that now you see over here this little little lip over here this little Edge watch we're going to pick it up slowly and just watch what I'm doing and look at that okay you ready look at that look at that now we got them all but now we have to find her um no that's not the center [Music] oh look at that we got the center of gravity it's exactly balanced you guys want to try to do that okay try so remember put one on the boat like this just put one like this over here and now start going back and forth back and forth there you go and the other way keep on going keep on going yes go back and forth until you have one left slowly slowly yes put it up put it up over there let's see if you can do it let's see look at that give yourself a big round of applause the concept of center of gravity we use in many many different things Building Bridges building houses and even juggling let me show you something really awesome here we have three balls red blue and yellow did you know Dr schnitzel can juggle we can do all sorts of Tricks we can do a trick that's like climbing here we go climbing up ladder and sometimes we can make them both we go back and forth back and forth and look at that yeah sometimes Dr schnitzel knows how to do it under his leg let's see if we can do it under his leg and oh look at that and should we do four balls look what I have over here four balls let's try this it's a little scary don't laugh at me if if it drops okay here goes let's try to do this and look at that we got four balls look at that amazing did you know that Dr schnitzel can juggle blindfolded I'm gonna take a blindfold and we're gonna blindfold myself and I'm gonna turn around for a second don't look okay here goes and let's put this right over here [Music] like this watch watch watch look at that Dr schnitzel knows how to juggle blindfolded look at that I'm just joking okay we're gonna start off with three rings and these rings are very equally balanced we can do two one two and one two and one just like that yeah we could do two and one two and one and should we do four let's do four let's see if we can do four and I love to do this beautiful Little Flower okay let's do four sometimes it drops hopefully it's gonna work and [Music] yeah good job to me here we have three juggling clubs did you know that companies who make the juggling cups they work very very hard to make them balance properly so this over here even though it's bigger weighs as much as this over here let me show you what we can do [Music] yeah this is nice and easy because they're balanced properly let's move this way over here should we do it under Dr sissel's leg let's see if we can do it on the doctors away here it goes and yeah that was awesome let's see what else we can do should we do doubles let's do doubles here goes one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen Seventeen eighty ninety twenty foreign [Music] hold on I have an idea why don't we take this should we juggle it yeah let's see if we can jog here now is this balanced I don't know it's not balanced let's try to balance it it's not balanced but let's see if we can juggle this properly here goes oh yeah it's very hard it's not as easy as what we did before the three balanced ones foreign [Music] I think this bike is a little bit small you see I'm trying to use the principle of center of gravity to balance on this the problem is that I can't really balance on it I think I need something a little bit bigger [Music] we have here a unicycle okay I'm gonna try to get on okay but I'm gonna need a helper okay Ezra come stand over here I'm gonna hold on to your head okay here back up a little bit a little bit hold on one second let me get on this is a little scary I don't know is this a good idea okay labe come over here Ori hold on to his head on both sides no both sides of his head by his ears yeah like that hold it tight don't let it shake okay I'm gonna try to get on okay now should I let go should I let go now we need to have the center of gravity right if I lean too much to the right it's not centered gravity if I leave too much to the left it's not hold your head up straight hold your head up straight and if I go too much I need you again okay okay okay let's go backwards go backwards backwards more backwards more backwards more backwards okay okay stay where you are I'm gonna try to ride here goes [Music] hey the doctor schnitzel painted yellow and blue now this stick over here is exactly I believe four feet let's see two feet over here and two yes four feet which means that the center of gravity is right over here by this line we're gonna take this and put it on top of labe's head so labe comes down in the middle let's see what happens if we put it in the middle will it balance don't move like look at that it's exactly in the middle but wait what happens if I move it like this should I let go okay here goes it falls that's right it has to be exactly balanced now look what we have over here these are called cigar boxes many many years ago there used to be jugglers who would use these cigar boxes to juggle now we're gonna take it and move it just like that very carefully who knows what special mitzvah does this look like yes but wait is this a menorah that we use it only has seven branches so what Menorah is this from from the base how make that's very very good now watch what we can do we are going to use the concept of center of gravity to try to balance this watch I'm going to slowly go like this and turn it like this slowly and I'm going to go like that slowly slowly it's very scary okay and then if I Let Go is it going to fall no oh well yeah it's gonna fall because it's not the center of gravity but we're going to move it over here to the middle and then we're going to put this over here and now Dr schnitzel is going to try to balance this on top of my nose should I do that I don't want it to fall okay now lame I want to do this it's going to be very fun blame I want you to go on top of Ezra's head and I want Ezra you're gonna then go with lame on top of your head on top of ori's head and then I'm gonna go on top of all of your head should we do that should we do that yes [Music] now what we're gonna do is we are going to show you how we balance this very carefully so let's put it in the middle and let's see oh perfect now I have over here two little red blocks that I found in my kids toy room we're gonna put this aside over here should I let go probably not it's gonna fall but what if we put it exactly they weigh the same and we put them exactly at the end look at that now let's take a blue and a yellow we're gonna do a blue on this side on top of that and a yellow on this side okay I look yeah now wait we have over here two twin Menchies one has a little tadaka push cut anybody here like to give to DACA yeah and one here has a hummus who here likes to learn Tyra I love to learn Tyra now should we put this over here and it's over here what if we put one you think this just a little oh it weighs so light do you think it's gonna throw the whole thing off balance yeah all right let's see yeah we don't want to do that so let's put this over here and this over here the exact same is there a way for us to put not just these two but those three as well and this all on one side and for it to still stay up no think think where's the center of gravity in the middle what happens if we move the metal oh let me show you how we'll go there and that will go there and now if I Let Go what's going to happen it's gonna fall but what happens if I move the center of gravity which way should I move it to you right oh is this enough no it's not enough should we do it here no not enough how about now oh look at that we have all this on this side but what's happening because the center of gravity is moved to here so this extra bit weighs like that and therefore this over here is the center of gravity by the way that's how cranes that build big big skyscrapers you ever wonder how they work you have over here like this chain and picks a very big boxes right and over here it's just a small amount because over here they have these like weights that holds down right so that's how this works do you think we can put this on the side will it fall I don't know this is a good idea let's try I think we need to move it a little more let's try to move it even more is this working oh look at that wait let's go even higher let's go even higher is it gonna go oh let's go even higher oh wait wait wait let's move it just a little bit more there you go there you go and now so we put the tape measure this tape measure is pretty heavy should we put this on top wasn't that amazing that's the power of gravity we're gonna take our little boxes over here and let's see let's pile this over here and we're gonna put this over here then we're gonna put these two over here then we're gonna put one over here then this is gonna go right over here then we're gonna take this over here watch this here back up a little bit and come stand right over here and watch watch watch balance but wait a second Ori I want you to have your head right over here yes not touching this just over there good light yeah perfect then move a little bit this way can we good put your feet straight good job lie down nicely and I want you as well stand yeah lie down over here make sure your head doesn't touch the red box perfect we got the two brothers now wait we're gonna take a little bit of a bowl we're gonna put one side over here and one side over here then look what I have over here we're gonna take water oh I don't know is this a good idea let's put a little bit like this just about a fourth of a cup and then we're gonna take a little bit the same amount we want to have this exact same amount and we're going to see if we can try to balance this exactly perfect I'm going to pour in there and there if I pour it too much on this side the water is going to go fly I got your head or on top of your head if I do it over here we got to do it exactly the middle now wait a second you know what I have an idea I'm gonna take duck you should need to toilet paper and we're gonna cover your eyes just like that okay hey no laughing on Sunday okay here goes like that and instead of using this why don't we use should we do that should we pour this on top of his head and this on top of his head should we do that wait then they're gonna get full of ketchup and mustard do we want to see him full of ketchup and mustard no they're very very kind boys we don't want to see them all dirty so instead okay how you guys doing over there you guys are okay okay here goes we gotta cover your eyes we don't want it to go in your eyes okay just like that perfect okay stay here relax I don't know is this a good idea okay we're gonna do it slowly we're gonna do a little bit here okay and then a little bit over here over here and then a little bit over here stay where you are a little bit okay too much okay and then over here okay and then let's do let's see if we can get the whole thing not to fall on top of them okay hey no laughing you guys you're making me laugh okay look at it not too much for trying to make sure that it does it cool not too much and then we're gonna go like this like that did you get wet did you go west a little bit give them a big round of applause up we have over here a gigantic sea salt let's take a little bottle and put this right over here oh it balances it now what happens if I take this orange soda and put it over here is it going to be balanced perfectly look at that so let's take this cookie and put it right over here at the end look at that it's a little heavy over there let's put this over here and oh equally balanced and we have over here Black and Whites who likes black and white I love Black and Whites you're gonna go over there and you're gonna go over there and what else we got oh look at these cookies over here oh I love cookies let's put this on the end right over here let's see what happens oh that definitely weighs it down and now let's see if we can get this to go back to the other side now wait a second oh we got some candies do you like chocolate candy you like chocolate candy yeah okay let's put them over here let's put them over here do you know that the rambam teaches us that the entire world is like on a big scale on one side we have all the mid spices and the other side we have they are various and it scales exactly equal and if we do one little Mitzvah what happens we tip the scale let's put it on the right side and let's see what happens if we do one little mix of a pretend like this is a Mitzvah let's put it over there and let's see if we could tip the scale let's put this over here on the right side and see what happens look at that it leans towards the right the side is heavier could we take our helpers here our boys and put them on top over there yeah let's do that Ezra I want you to slowly put your foot yeah one foot stand slowly we stand on it now I want you Ori I want you to step on that side good let's see who weighs more slowly slowly what if I go on his side that's gonna happen let's go over here hold on I'm gonna try to go over here let's see if we can balance him look at that should I jump we jump okay stay here where you are one two three that was scary that's very very scary now wait a second hold on stay right there I'm gonna move slowly to the middle slowly slowly slowly slowly slowly look at that and if I go over here right oh we're throwing him off but wait is it possible for me and only to be on one side and to have Ezra way more than us or at least weigh us down is it possible based on what we just learned with Center gravity how do we do it oh we have to remove it oh we moved this to move the middle move the center of gravity should we do that okay okay now I want you Ori to stand over there yes slowly stand all the way down good good good right over there good now I want I'm gonna go on this side over here now Ezra you think you could stand on there and try to see if Ezra alone could weigh more than us now that we move the center of gravity go yes slowly slowly go all the way down down good look at that we are both on this side and Ezra do not jump because if he jumps we're gonna go flying yeah [Music] if I go backwards [Music] I want you guys to try something that you can do in your house for this you're gonna need a ruler I want you to hold it like this in the middle find the center of gravity hold it with two fingers on the bottom and your thumb like this just like that okay then you're gonna take one blue on one side Laffy Taffy anybody here like laffy tappy who likes laughing zombies I love laffy tubby and then you're going to take the yellow and put it on the other side now slowly very steady you're going to put one finger out hold it like this and try to balance it try to balance it up try again see what I'm doing here you're finding the center oh look at that try to do it who can try to do that now look what I'm doing I'm doing three on one side like we did with the big blue yellow stick I'm going to do three on one side and then I want to find the center of gravity oh this is really hard you got to move it to the side move the center of gravity to the middle look at that look at that look at that I got three on one side and one on the other side I found Center gravity we're leaving how's it going [Music]
