 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the mysterious moving chads. As always, adult supervision is required. What you need for this experiment is a pencil, a 3x5 index card, a hole punch, mineral oil, bottle, and a clear cup. So to set up this experiment, you're going to take your pencil and your 3x5 index card and you're going to draw a very, very dark spot on there large enough to do a hole punch about 20 to 30 times. So you might need to make a little bit more. So you're going to fill it in very, very dark spot on one side only of the index card. And then we're going to, once we get that completely dark with your pencil, then we're going to take the hole punch and punch out some holes. So when you're finished about that size, that's what it's going to look like. Then you're going to grab your hole punch and you're going to cut out your holes, which are called chads, which I learned today. I did not know that. Most people probably do know that. I did not know that. That's something I learned today, which is pretty cool. Anyway, you're going to do anywhere from 20 to 30 of these holes. And so make sure you're just getting the dark spots, make sure they're complete circles. And once we get that in, then we're going to do the rest of the setup. So go ahead and put those chads in the corner there. Then we're going to take some water in a bottle. Just about, you know, it doesn't matter how much, just a little bit of the bottle. And then you're going to add some mineral oil about one centimeter just on the surface of it. So lightly pour it in so the oil stayed to the top and just pour it in just enough to be able to get about one centimeter or so. It doesn't have to be exact. So you can see it right here. We have a layer. I'll pull it in a little closer. You can see about one centimeter. Let me measure it. And we have pretty good about one centimeter, pretty good either. Anyway, so now we're going to take our chads, right, the hole punch holes. It doesn't matter if they're what order they're in, white or black and pour them into your bottle. So just go ahead and get all those into the bottle. And good job. And then we're going to put the cap on, and then we're going to shake it very good. So we want to shake it so it's all mixed up, the mineral oil, the water and the chads. You want to make sure it's you're going to shake it for about, you know, let's say 10 or 15 seconds to make sure it's completely shaken up because we want the mineral oil, water and chads completely mixed up. And then from there, we're going to be pouring it into the clear cup. So now we're ready to do the experiment and get your clear cup. And we're going to pour the solution after we shook it up, do not wait, pour it right away and observe what's going on. As you see, there's a lot of movement going on, hence the name the mysterious moving chads, right? So they're all starting to move around. And mysteriously, they're all going to pop up with the lead facing up, and which I'm going to tell you the science behind that. So as they continue to flip up there, I'm going to do the experiment one more time and explain the science behind it. So the amazing experiment always yields excellent results. I love this one. When the contents of the bottle are poured into the cup, the chads will be floating in the interface between the water and the oil, but they'll all be oriented in the same direction, which is the dark side up and the white side down. A pencil lead is not really made of lead, but graphite, which is a form of a carbon. As all pure elements, graphite is a nonpolar in nature. Mineral oil is also nonpolar. Therefore, the nonpolar graphite side of the chads, the hole punches, which will always be attracted to the nonpolar mineral oil. This is further verification of the principle of that like dissolves like. I hope you enjoyed this video. Remember to click thumbs up and to subscribe. Thanks for watching.
