 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the energy stick. You touch both ends and you make a human circuit. What you need for this experiment is the energy stick. See description for a link where I got mine. My name is Ken and today's experiment is the energy stick. And I have my three new friends here. I have Carson, Grayson, Parker. The energy stick as you notice has two silver rings. One on each side. When you touch the both rings at the same time the energy stick begins to light up flashing and makes a sounding off with the silent. When you let go of one of the silver rings it will go silent. So we're going to try some different objects to find out if they conduct electricity. So I'm going to have my volunteers make a hypothesis every time we try a different object. And they're going to help me assist this so the energy stick. So to be able to make this work we have to be in a circle. A circuit is a circle and then it will light up. So um when you touch the circuit right this will buzz. You will get shocked it will buzz right. So if um let's say if we go. Is your in the front of the banana? No I'm going to wait this. If I if you touch this and hold this right. I hold it? Wait is it going to light up? Yes. Yes? No? No. No. Why not? Because you don't have any energy. Kinetic energy. Well we don't have a circuit yet. What's the circle? What's the circuit? A circuit is something that has a bunch of energy and electricity. Right but it has to be in a circle. It has to be in a circle. So let's go. If I hand it to you. Okay good good. Let's see if I touch it. Will it light up? Yes. Will it light up? Okay. All right. I need to retire. All right you can try both hands. You gotta touch the metal though. Okay. One at a time boys. One at a time. Okay. So what's wrong here? Remember a circuit is a circle. Is this a circle? One one. Go grab this. Grab this. Now grab this. No I know what to do. Because we're a circle. Now grab his hand. Grab his hand. Don't leave him out. Right here. Touch the metal. Why isn't it going? We're in a circle. Let's try this one more time. What's the second? This is why it's science right? It's when atoms it burnt out. Dang it poop. Wow. You overloaded the circuit. That's not good. We're gonna have to. Two science projects. Two science projects. Okay we're gonna try it again. I wanna do it. Try this one. Loose wire. Go. There it goes. Little no function right? See? Watch this. Watch this too. Pull this down just a tad. Now grab this. Now touch his arm. So let's try some new. So your parents say. Look it. Let's try this. I'm gonna eat this later. Let's not squeeze it. Okay so back up for a second. This is water. So your parents tell you don't play with water in electricity. Because you get electricity. Absolutely. Right? Yeah. So if I hand this to you. Can I touch the water? Yeah you're gonna touch the water. Will it light up if you touch the water? Yes. Why doesn't it light up? Oh no. I have to make a circle. Right? You don't have to touch me. You don't have to touch me. Because electricity goes through water. How am I gonna get my hand wet? Just like that. Let's let the other guy try it. Let's let the other guy try it. Is it gonna work? Do you want me to put my finger in? Yes. So electricity goes through this. Now here's a piece of wood. Is it gonna light up? Yes. Yes. Yeah what should I guess? No. Electricity doesn't go through wood right? Yeah so it doesn't light up. It doesn't matter if you have water on there. It's still not gonna go through the wood. Do you think it's gonna light up? Yes. Can I try it? Do you think it's gonna light up? Yeah you already tried it. Try the banana. You guys don't need to rub your hands. That's not the secret. One second. Hand down a little bit. Ready? Wait it worked. You touched my hand. You know why it lights up? You know why it lights up? There's liquid inside the banana. Okay. Right? So the liquid's like the water. It's like the water. It's plastic right? You think it's gonna light up? It doesn't go through plastic right? So it's got a lot of water in it right? No. You guys are thinking of all this stuff. It's not gonna get to a rock. It's flashed. Yeah just maybe a little water went across right? You get to a serious free present. Oh wait there is water in there. Now put your fingers in his coffee. No. Okay. So how does it work? So when you touch both silver rings at the same time the tiny negative charges called electrons flow through your skin around your body from one end to the energy stick to the other. The flashing lights and buzzing sound are what's telling you that your body, your skin is a conductor of electricity. Hey so we're going to end so you have to say thanks for watching this video. Thanks for watching.
