 Hey, welcome back to Kids Fun Science. My name is Ken and today's experiment is the inertia hat So I had a another subscriber that I subscribe to and they subscribe to me. He's out of Lebanon It's our Amali's adventures for all kids, right? If you look in the description, I'll show you where you should go there check out his channel It's really cool. So he asked me to do a collaboration video with him on the inertia hat, right? He calls it the science hat The inertia hat which is basically just a coat hanger that we'll put together And with two tennis balls and then it's Newton's first law so I'm going to show you his video his experiment my experiment and How to make that experiment afterwards next So what you need for this experiment is wire coat hanger two tennis balls or two objects and a volunteer Please remember to click that subscribe button and thumbs up it does help our channel. Thank you But we're gonna use Something in order to protect my hat my hat because of the metal will be very hard Now what does Newton's first law of motion is saying? It says that any object I trust will remain at rest Unless an external force is applied to it. Okay. Now I'm gonna rotate And we can see this hat will stay at rest See the hat stayed Did not rotate yeah, and I rotate it right and now I'm gonna apply a force And it will rotate. This means that when we apply a force to the hat it is rotating Just like Newton stated Okay, now let me try again The head is at rest The head is at rest and we are not applying any force on it. Okay. Let me balance it Yeah, this is rotating some small motion to the head because of the imbalance of the Okay, yeah, I say bye So here's my experiment with a inertia hat So for Norton's first law be patient It does take time to form it and get it exactly to work, but it's well worth it once you get it done So once you put it up, you have to balance it on your head Make sure you get to that right point and you'll notice that an object at rest will stay at rest and then a Object in motion will stay in motion, right? So until the friction from the hanger on top of my head and then it eventually will come to a stop But that is pretty cool So if we take it here, and then we put it at rest and I move my body around an object should stay You got to keep it balanced on your head, which isn't at times the easiest Put it right here and object at rest Should stay at rest, right? So it does move a little bit because I'm wobbling back and forth But it pretty much does stay at rest when you do the spin And it doesn't rotate with you, right? So you can spin around And it stays at rest. So I hope you enjoy this video and if you did Please get into motion and click that subscribe button and thanks for watching So for the setup you're gonna take a wirecourt hanger and you're going to unravel it Be careful it one end is sharp and you're just going to basically straighten it all the way out Now if you don't have a wire coat hanger, you need about 41 inches or 104 centimeters of wire a thick wire So once you get that completely stretched out You're going to try to get the exact middle and fold it over just like that in the middle And then from there you're going to make like an M So you're going to curve down each side and try to keep them even as possible Mine's a little bit off and from there you get out a little bit tweaking You have to be able to Pull it in and out to try to get it straightened up a little bit just kind of bend the wire back and forth It's a little bit of an art and have a little bit of a patience After that you're going to take a little like a box cutter poke a little hole in it and Insert your ends for each with a tennis ball for of each of the coat hangers So once you cut your hanger out and you get it all set up part of I think the hardest part is to get The balance so it's straight up and down and so you want to be able to Way I test it instead of on top of my head is on my finger and you can see it's kind of an angle That's okay. You can always just tweak it just bend it in a little bit and you know getting the right Way so it could balance right so that's pretty much the hardest part so this is a smaller version of Newton's first law Object that's that rest stays at rest an object emotional stay in motion So here I just got it on top of a water bottle Just a thinner wire so you don't need a coat hanger and then a printed out a couple of airplanes and then hot glued them to the Bottom so as you can see you push it and object in motion will stay in motion until the friction of the wire And the top of the cap slowly will stop it But this actually goes a lot longer than you on top of your head because there's less friction So it will go a long ways So here's an object in rest will stay at rest and if you look at the three colors the green the black and the red I'm spinning the bottle right but the two objects of plane are at rest So they're staying they do not move as I spin the bottle just like I did when I moved around with my head But there's a lot more friction. So this personally is one of my favorites. I love doing this one as Newton's first law and remember when you hot glue the airplanes on to the wire make sure the wire runs all the way to the bottom of the planes and Make sure the planes are facing the opposite direction. So I just made a little loop there and you hot glue it on the bottom and Make sure the planes are facing otherwise you have one go of the opposite direction and Thanks for watching
