 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is Easter egg science. So three hands-on fun experiments you can do at your house. What you need for this experiment is iodine salt, there's regular household salt, a hard boiled egg, and a raw egg. So experiment one is to figure out if it's a raw or hard boiled egg. Experiment two is you're going to spin the raw egg, stop it, and then it spins again. And experiment three is a stand-up egg. Okay, well here I've got a great hands-on experiment for kids at home, especially right around Easter, right? So I got two eggs. I got one as a raw and one as a hard boiled, but I don't remember which one. Because when I hard boiled them, I kind of intermixed them back in, so now I've got to figure it out. So what I could do is I could shake them, and I can't really tell a difference. I could hold them, and I don't really can tell, but there is a way we're able to tell, right? So if we put one down on the side, and we take another one, and we grab the ends, and we spin it, you can see it's just spinning around right here, right? So this must be the raw egg, right? So it wobbles, and it spins because the egg inside is liquid, right? So when the raw egg is spinning, the liquid inside sloshes around, and the effect of the egg spins back and forth, right? So the egg will just spin and eventually come to a stop. So this is because of Newton's first law of motion. So the law states if an object in motion remains in motion, unless an external force stops it, right? So put it more simply. Newton's first law says if something is moving, and it keeps moving, unless something else stops it. So we have our example of first law of motion here with the raw egg. So this is something else you could try with this. Now we figured out this is probably the raw egg, but let's figure out something else. We're going to spin it, then I'm going to stop it, and we're going to see that the liquid is still moving even though I stopped it. And when I release my finger, it should start spinning again. See that? That's pretty cool right there, right? So I'm spinning it, and the liquid is going around in a circle because we know it's the raw egg. And even though I stopped the egg, right, and when I release it, it starts to spin again one more time. That is cool science right there. So since we know this is the raw one, right, we're going to get to the hard boiled one. So now there's no liquid inside, so nothing's going to move around. So when I spin it, you spin it right, you spin it wrong, it goes off the table. Woo! It goes right there. Anyway, because it is solid, it's able to spin all the way straight up, and therefore I know it's the hard boiled egg. Give it another try. Very cool. Right there, great science, because of all the, it's all solid, right? Alright, for the second experiment, we're going to have a hard boiled or soft boiled, doesn't matter. You're going to use some table salt because it's got a rectangle in squared shape, so it's going to help us. If we're going to try to stand an egg up on its own, even on the big end, it doesn't want to stand up, right? Because it's just, it's round, or it's oval, and it won't stand up. But with the cube shape salt, or the rectangle shape, it'll help build a base so we can stand it up, right? So we sprinkle a little bit of salt here. Take your egg, I'm going to do the small end. It's not very easy, I'll tell you that. Because when you go to release, your hand hits it every time, so you have to be very gentle. But I'm going to show you the salts around it. You can see it's holding it up, standing straight up, which is pretty cool. Gently blow the salt away, and there you go, you got your egg right there, stand up egg.
