 Welcome back to Kids Fun Science. My name is Ken and today's experiment is a swing in magnets. As always adult supervision is required. What you need for this experiment is six skewers, four rubber bands, yarn, one ceramic ring magnet and three ceramic rectangle magnets. To put this experiment together you're going to take your skewers two at a time and you kind of make a little cross there like that at the end. Be careful the ends are a little sharp and then take a magnet and twist it around until you cannot twist it anymore. I just continue to twist it. It doesn't have to be all the way but close to tight. Then you take one of the other ends and take a third skewer and you're going to do the same thing putting it like a little bit of a cross there or a T shape and take the rubber band and go around it as many times as you can with your rubber band. Depending on the size of the rubber band it might get more twist than others but until it's nice and tight and then you're going to spread it out until you have a triangle and you're going to do the last one for this is for the base of the experiment and so you're going to take that and then you're going to make a T again and take a rubber band and we're going to secure this off by wrapping it around as many times as we can and then after we get this completely tight here then we have our base finished which is a triangle. So that's the first part of it and now we're going to work on the the second part the top part and what we're going to do for the top part is we're going to take all three of the skewers at the same time this time. They don't have to be crossed over. I'm going to start with the non pointed ends so make the top part the non pointed ends just put them all together and wrap the fourth rubber band around until it's completely tight and once it's completely tight then you're you're ready to go and from there we're going to brace it out like a teepee you know so we can make a triangle or a pyramid coming up so now that we have that there we're going to take one corner and slide it in between one of the rubber band strands and push up a little bit so you have a little bit of a base and don't let it fall like that and then once we get it in then we're going to slide down the second one over to the second side there pull a piece of rubber band out and put that base in you want it about a half inch up it doesn't have to be completely up but big enough for your rectangle ceramic magnet to fit underneath it and take your third one and then even them out and then you've got your base set your all set there on the triangle or pyramid with the skewers and you can see the ceramic uh magnet has to be able to fit under it um if you want to make them even you can kind of just go around and make sure that it fits under all sides and then you're ready to go and here's what it looks like from the top view and then when you come down uh you can see that it's just up about a half inch just enough for the ceramic uh rectangle magnet to go under and now we're ready to put on the yarn so the yarn is the length of the skewer um and so just cut a piece of the yarn that's the length of the skewer and then you take your round ceramic magnet and then you're going to tie the yarn in there it doesn't have to be yarn um it could be any kind of string i just happen to have yarn sitting around um in the experiment drawer and so take that and tie that off so um it's got a knot on it so it's secure and then we're going to hang it and we want it to be about an inch above the ground so this might take a couple times to get it tied right um but once you do i'm going to move these magnets out of the way um and then we're going to tie a knot and hang it down uh from from the top and try to get it about an inch off so uh this might take a couple tries and it doesn't have to be a double knot or anything but once you slip it on there and you have it and it's to the right measurement just like that then you're able to start doing the experiment so we'll check it with our hand we kind of want it to be just far enough off the ground there just a little bit over your your finger if your magnets are catching on them as you'll see then you're going to want to retire the knot and pull it up so that's what it looks like and now we're ready to do the experiment so the first experiment is just having the three rectangle magnets um hanging out a little bit farther and you can see they all kind of want to pull out um so it's going to kind of go to one or the other if it gets too close they're going to like catch on to it so you just want it just far enough apart um you can give it a hit um so it goes back and forth and it'll kind of uh pull back and forth as it's getting drawn to which magnets the closest and in one a pull from the other with momentum so that's kind of cool so you give your own little test on swirling that magnet around or just let it go by itself uh I kind of like let it fling up and see how that one works and see which one it really pulls to uh so it's pretty cool uh doing this one here right I love this one a lot so this time I moved the the magnets the inside of the of the triangles there and you can see it's got a little bit more reaction it's uh flipping the magnet a lot quicker this way and I don't really have to hit it it's just going back and forth and spinning kind of doing a rotation this way so you can play around on different locations you put your magnets to see how it's going to affect it so now this experiment you want to hold the magnet completely still before you start and then we're just going to use our hand on the outside with one of the magnets and just going back and forth and you're able to spin it by getting the north south coming by really quickly we'll spin the magnet so if once again if you get too close it's just going to attach to it um I'm on the outside of the triangle and I'm just moving it back and forth to get it to spin and it's pretty crazy it sometimes it starts winding up so much the yarn starts to get tangled up and it really starts to spin off so uh this was kind of a fun one there I got a little bit too close it wants to there there it goes it wants to attach to it so it's kind of an art I guess to get as close as possible but your idea is you want to get this to spin by just moving the magnet by it so you could go quicker or a little bit slower and the third and final experiment is I just got two magnets on the bottom and uh when you swing it over it's kind of like a dancing magnet here so as it swings back and forth and it tries to come to a stop it just can't come to a stop it just wants to keep going back and forth uh it'll actually go for a very long time so you know give it a spin and see how long it'll last try three magnets to see what happens uh but it's kind of cool when you swing it it'll definitely start to come to a stop and then it just starts dancing I hope you enjoyed this video remember to
