 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is magnetic cereal and the secret ingredients. As always adult supervision is required. What you need for this experiment is cereal with iron in it, a clear cup, a spoon or a fork, a ziplock bag and very strong magnets. You gotta wait for me to sit down, don't you? My name's Ken. My name's Ken and the star? Grace. All right. So what do we have here? Total cereal. It's 100%. Well it's zero sugar so you probably wouldn't like it, right? And so how much iron is in here? We know there's a lot of vitamins and minerals but how much iron? 100%. So this is the same kind of iron that are made out of nails, right? And they put it in your cereal and we're gonna show you this iron with this experiment. There's a lot of 100% like there's a lot of vitamins. Uno, dos, tres. All right, rip that box open. First time opening one? No. Have you opened cereal before? Yeah. But it's never been this hard? No. There you go. I don't see any of that. Wait can I throw the box? Sure. There you go. Don't need no box. We're just gonna open this up. We're gonna pour something to a bag. We're gonna extract the iron out of the total cereal because they're supposed to be 100% and we're gonna find out how much they're rich, right? So remember, don't spill it. That doesn't seem to be working, Grace. All right, that's good after Grace spills half of it. All right, so now we got the cereal in a ziplock and we're gonna put some water in it. You want to do that? Can you get it in? And then we're gonna close it and you gotta let it sit for about 20 minutes. So we'll check back after 20 minutes. Two hours later. All right, so we had to wait 20 minutes so this becomes big mush right here, right? I would not want to eat that. No. It looks like pumpkin pie. It does. And so what we're gonna try to do is pull the iron out of it, right? So I'm gonna switch the camera around and we're gonna put it down and then we're gonna take a high-power magnet and we're gonna try to pull the iron out. All right, so we took the solution we have in the ziplock bag and we put it in a cup and we're gonna, Grace is gonna swirl it around and hold the magnets to the side of the cup. They try to get the iron to separate from the, pull it up a little bit halfway and spin it around. Pull it away, pull the magnet away. Oh, you see the iron? That's cool. Did you see it? Right here. There's the sum of the iron right there. That's so cool. Huh? Whoo! So the science behind this, believe it or not, many breakfast cereals contain pure iron. Basically it's the same thing that's used to make nails that you might use to build your house. Iron is an essential nutrient for your elements so it's added to cereals to make it more nutritious. Pyrochloric acid and other chemicals in your digestive system track change the tiny particles of iron in the cereal that form into your body and absorb them. The red blood cells contain a compound that carries oxygen. That compound molecule is made up of iron and other elements. The lack of iron can cause fatigue, reduced resistance to sickness and disease, and increase heart and respiratory rate. So it's very important to get your iron intake. Here what we're doing is just pulling it out by sloshing around the liquid in the total cereal and putting the heavy magnet on the outside and as you can see pulling out the iron inside the cereal, which is pretty cool. So the more liquid it is and you swirl it, you get the iron to separate out of the cereal and then let go and look at that. That's a lot of iron. That's the same kind of iron that you get if that's made up of nail. You're moving it. I'm moving iron. That's awesome. Can't see it though. Cool. All right well that's how you separate iron out of a cereal. One more time. Oh that's a lot. Nice. All right. All right so what we're doing here is Grace has picked out some of the larger pieces. I've never seen a piece that big before. And we know there's iron on these pieces so we're gonna lay it on top of water and then see if we could pull them with a magnet. So we'll try this piece first and then Grace is gonna grab the magnet and put it close to it, not on it, and see if it pulls towards it. Is it pulling towards it? Yeah. Don't let it touch. So it is pulling towards it. So you can see the iron in it is actually attracted to it, right? What happens if you touch it? It'll go right to it. It'll stick to it. You can probably pick it up. No. No it's not strong enough. It's strong enough to pull. Strong enough to pull but it won't attach to it, right? Let's try another piece that becomes as long as it's buoyant then it should pull towards you. Here it goes. That one's really moving, huh? That one probably has more iron in it. It's bigger. Let me try it. So far actually the smaller one works best. It's like I have a string on it. Okay, that video seems really interesting. Oh and that video too. Click on them at the same time.
