00:01 The experiments you will see
00:02 have been carefully done by professionals, 00:04 and should not be tried at home 00:05 without parental guidance. 00:07 Please follow the caution signs throughout this program. 00:33 Welcome, kids. 00:34 We are so glad you could join us today. 00:36 We are going to learn some wonderful things 00:38 about our Creator, 00:40 and I think it's through magnets, 00:41 but let me introduce you to Professor Roy. 00:44 And at the end over here, I have William, 00:47 Aiden, 00:48 Miss Aubrey and Noellia. 00:51 And what are we going to learn about magnets? 00:53 I like playing with magnets. How about you? 00:55 Yeah, magnets are fun, aren't they? 00:56 Yes, they are. 00:58 So what is a magnet anyway? 00:59 So what makes a magnet? 01:01 Well, we've got some very, very strong magnets here today. 01:03 In fact, I've got some little magnets right here, 01:06 these little magnets right here, 01:07 the little tiny ones right there. 01:09 These happened to be 01:10 some of the strongest magnets in the world. 01:12 So how do they make a magnet? 01:13 What makes up a magnet? 01:15 Well, I'm gonna tell you what makes up a magnet. 01:18 What we're going to do is 01:19 we're going to illustrate it, okay? 01:21 So if you kids will come out here 01:22 and what we've got, 01:24 we've got this big old rope right here, 01:26 and we're going to have you hang on to the rope, 01:28 hang on to those loops of the rope. 01:30 Okay. There we go. 01:31 We've got the loops of the rope. 01:33 Now, each one of our students right here, 01:34 each one of our guys, 01:36 they're gonna represent atoms, okay? 01:38 Atoms 'cause the world is made out of atom, 01:40 everything is made out of a combination of atoms, 01:42 aren't they? 01:43 So magnets have atoms in them, don't they? 01:46 Okay. 01:47 And the atoms all have electrical sphere. 01:50 So what we're going to do is 01:52 we're going to have you pull back on the rope, 01:55 pull back on the rope. 01:56 Each one of those atoms 01:58 is pulling in a different direction 01:59 and the rope isn't going anywhere. 02:01 It's just staying right there. 02:03 Well, a magnet has all the domains 02:05 of the atoms are all lined up 02:07 and that's what makes it a very, very strong magnet. 02:10 So everybody turn and turn in this direction right here 02:13 and go ahead and walk in that direction. 02:17 Now we just turn them into a magnet 02:19 because now we made some work. 02:21 They had some work 02:22 and they all are going in that direction. 02:23 You can go ahead 02:25 and just drop the rope right there 02:26 and come back around here. 02:28 So then magnets are made out of elements. 02:30 And these elements in these neodymium magnets 02:33 happened to be boron and iron and neodymium, 02:37 which is really cool and boron and iron, 02:38 and they mix them all up. 02:40 They crush them 02:41 and they press them into a mold. 02:43 Any shape you want, 02:44 you can just about make a magnet, 02:45 but it's not a magnet 02:47 until they line up all the domains of the atoms, 02:48 just like they did when they walked the rope 02:50 across the way right here, 02:52 all the domains have to be lined up. 02:55 Hey, what's the largest magnet you've ever seen? 02:59 You ever seen big magnets? 03:01 Yeah. Okay. 03:03 Well, you might have some magnets 03:04 on your refrigerator. 03:05 Have you had some magnets on your refrigerator 03:07 and they stick to stuff, don't they? 03:09 Yes, they stick to some types of metal. 03:11 Well, the largest magnet I've ever seen is the earth. 03:14 And we're standing on the earth right now. 03:16 And the earth has a magnetic sphere, 03:18 which is interesting. 03:20 God created it that way. 03:21 And because we have a liquid core 03:24 and the earth is spinning. 03:27 And that creates 03:28 a very, very strong magnetic field. 03:30 That magnetic field is good 03:32 because it keeps us from getting bombarded 03:34 with some very, very strong, 03:36 very, very deadly rays 03:38 that the sun give us like gamma rays and x-rays 03:41 and we need that protection, don't we? 03:44 And our atmosphere helps us as well. 03:46 Let's see what we got. 03:48 Let's go ahead and move this down here 03:49 out of our way. 03:50 So we've got some, 03:52 I've got some very, very strong magnets right here. 03:54 And let me go ahead and show you what we've got. 03:56 What I'd like to do is come in between you right here, 03:59 you two gals right here. 04:00 Would you hang on to the ends of these magnets right here? 04:03 We have two pipes 04:04 and the two pipes, they have red ends. 04:06 That's the North Pole 04:07 because magnets have poles, don't they? 04:09 North and South. 04:11 Here we have the North Pole and we have the South Pole, 04:14 and the magnets are sticking together. 04:16 We say that they do what? 04:18 They contract. 04:19 I mean, they're drawn together. 04:22 Okay. Can you pull them apart? 04:24 It's very, very strong. 04:25 Can you pull them apart? 04:28 Pull apart and maybe I can help. 04:33 Okay. Here, let me help. 04:34 There, there we go. 04:35 Whoa. Okay. 04:37 So what happens if we, so those are opposite, right? 04:39 Negative. 04:40 Not negative, but we have North and South. 04:42 Let's use both of the North Poles. 04:44 Let's see if they can make those touch? 04:46 Can you make those touch? 04:48 Can you make them touch and they're pushing away. 04:50 They're repelling. 04:52 Okay. So like poles repel. 04:54 Okay. Let's try this. Let's try the two South Poles. 04:56 Turn yours around like this. 04:58 Now we have two South Poles 04:59 and they're repelling each other. 05:00 They're pushing away. 05:02 Very, very strong, isn't it? 05:03 Very strong. 05:05 Don't be nervous. 05:06 Well, that's the side, just the ends. 05:08 Okay. 05:09 Why don't you turn yours around 05:10 and let's have North and South and they're going to... 05:12 They're gonna attract, so opposites do attract. 05:15 Hey, let's try the guys over here. 05:17 All right. Let's try the guys. 05:18 There you go. 05:20 Let's see if they can pull them apart. 05:21 We have North and South. 05:22 Can you guys pull those apart? 05:24 Can you pull them apart? 05:25 Don't fall. 05:26 You may have to help them. 05:28 Go ahead, take those apart. 05:29 Pull, pull, pull, pull, pull. Let me help them. 05:30 Okay, there we go. Let's try the two North Poles. 05:32 Let's see if they're, the two reds. 05:35 There you go, the two reds. 05:36 Can you get those together? 05:38 Is that strong? 05:40 They're repelling. They're pushing away. 05:42 They're pushing away. 05:43 Not the sides, just the very ends. 05:45 Just the very ends. 05:46 It's very strong. Okay. 05:48 Turn them both around. 05:49 Let's try the two South Pole ends. 05:51 The two South Pole ends 05:52 and can, will they attract or will they push away, repel? 05:59 Can you feel that? 06:00 It's very, very strong. Okay. 06:02 Why don't you turn yours around and you keep yours like it is. 06:04 Now, we have North and South. 06:05 Whoa, and they attract, don't they? 06:07 Hey, thank you. And you can let go. 06:08 Hey, let's see. 06:10 Hey, let's see if we can get a big, strong adult doing that. 06:14 All by myself. Yeah, by yourself. 06:16 Oh, not too bad. 06:18 Okay. You got no, no. 06:19 You got to turn them around. 06:20 We want to see... Oh, turn them around. 06:22 We wanna see them repel each other. 06:23 So, I have to see, do the South? 06:25 This is South. There you go, don't be nervous. 06:28 Whoa! 06:30 I can't do it. 06:31 I've done them with smoke. Okay. Turn them around. 06:33 Let's try the two North Pole ends. 06:35 And now that is pretty cool. 06:37 That is pretty cool. 06:38 That's a very, very strong magnet. 06:40 We're gonna set those down over here. 06:42 All right. 06:43 I should put my safety glasses on. 06:45 Now let's see what it got. 06:46 Now I've got a couple of spheres right here. 06:48 Now these are interesting. These are tennis balls. 06:50 Why don't you put your hands straight out. 06:51 Okay. 06:52 Let's see what we got right here. 06:54 You know, it's good to wash our hands, isn't it? 06:55 Yeah. We should wash our hands, right? 06:57 Because we, you know, 06:58 we're touching things all the time, 07:00 but let's put one of them underneath his hand 07:02 and we're gonna put another one on top of it, 07:03 hold it, hold it up. 07:05 Let's see what happens right here. 07:06 Oh, that's so cool. 07:07 Whoa! I think. Does he have sticky hands? 07:09 No, I think it's... 07:10 What do you think is inside the tennis balls? 07:13 Magnets. 07:15 They're magnets. 07:16 They're the same type of magnets 07:17 that we mentioned before, 07:19 neodymium magnet. 07:20 They're very, very strong. 07:21 You really don't have sticky hands. 07:23 It's just that magnetic force. 07:25 Can you feel the pressure of those two tennis balls? 07:28 Yeah. Yes. 07:29 So that magnetic sphere 07:30 is going all the way through his skin, 07:32 his bones, his muscles, his tendons. 07:35 And it's a force. 07:36 It's a very, very strong force, but we can't see it. 07:39 Isn't that interesting? 07:41 That is very interesting going through the body. 07:43 I know, it's really interesting. 07:44 So what I'm gonna do? 07:46 I'm gonna take this off like this 07:47 and they do stick together, don't they? 07:49 Why don't you try it on his hand? 07:50 Why don't you do it on his hand? 07:52 You put your hands straight out. 07:53 No, can you do it with him? 07:55 Hold it for him. Put it on his hand. 07:56 Here we go. There we go. 07:58 Put one of them underneath. 07:59 Wow! Look at that. 08:01 And it sticks to it. 08:02 I like that. 08:04 You know, we can use magnets to accelerate things. 08:07 So wait, what we have right here is 08:09 we've got a magnetic linear accelerator. 08:13 That's a big word, isn't it? It is. 08:15 But it's really kind of fun. 08:16 Let's say, can I get you to do something for me here? 08:18 Why don't you step down here like this 08:21 and put your hand up like this because you know what? 08:23 One of these little balls, 08:24 it should come out over here 08:26 and it should hit your hand, okay? 08:27 Can you catch it? 08:29 Right. Okay. Are you ready? 08:30 Get ready to catch it, it won't hurt. 08:32 It won't hurt. 08:33 That's easy for you to say. 08:35 So let's see what we got. 08:37 So I'm gonna take one of these little spheres. 08:38 These are just steel. 08:40 I'm gonna put it up here 08:41 and it's gonna hit this one right here. 08:43 What do you think is gonna happen to all of those? 08:45 What do you think is gonna happen you guys? 08:47 They're all gonna roll out. 08:48 Are they all gonna roll out? What do you guys think? 08:51 Let's try. Here we go. 08:52 Three, two, one, I'm gonna let it go. 08:53 Three, two, one. 08:55 I'm gonna let go. 08:56 And whoo! 08:58 So one went in and one came out. 09:01 Wow. Isn't that interesting? 09:02 Conservation of energy. How about that? 09:05 Hey, but let's have some more fun. 09:07 Okay. Are you ready? 09:08 That hurts your hand? 09:10 No, okay, good. 09:12 All right. 09:13 Let's try two, we're gonna try two. 09:14 All right. Get ready to catch it. 09:16 What do you think is gonna happen? 09:17 Are all those gonna go or one or two or none of them? 09:19 I think two of them are gonna go. 09:20 You think two of them? 09:21 You think one? Yeah. 09:23 What about you? Two. 09:24 Two. One. 09:25 One. Okay. 09:27 Let's try three, two, one countdown. 09:28 Three, two, one. 09:30 Let's let them go. 09:31 Well, two in and what? 09:32 Two out, two in and two out. 09:34 Now that's interesting, isn't it? 09:35 Okay. Conservation of energy. 09:38 All right. Okay. Let's do it another time. 09:40 Well, hang on. 09:42 Let's get these all organized, right? 09:43 Okay. I know I've got three. 09:45 Oh, hang on. 09:46 Whoa! Here we go. 09:47 What do you think is gonna happen now? 09:49 Three in, what's gonna happen on the other side? 09:52 Three out. Three out. 09:53 Hey, it sounds like a pattern. 09:55 You think it's a pattern? Yeah. 09:56 Okay, here we go. 09:58 Countdown three, two, one. 10:00 Let's go three in and... 10:02 Whoo! Three out. 10:03 Absolute. 10:04 Hey, but let's turn it into a magnetic accelerator 10:08 and a magnetic linear accelerator. 10:11 Are you ready for this? Yes. 10:12 Okay. Okay. 10:14 Well what I have right here, 10:15 let me get this one out right here. 10:17 I have another one right there. 10:19 Now this one is very, very special. 10:22 It doesn't look special, but it is special 10:25 because this is a very, very strong 10:26 neodymium magnet. 10:29 I'm gonna put it right here, like this. 10:30 Oh, hang on. 10:32 I'm gonna put it right here. 10:33 Let's put it right there. 10:35 All right. And then I'm gonna drop one. 10:37 Okay. Here we go. Are you ready? 10:39 Yes. Okay. 10:40 And it might speed up a little bit. 10:41 We need to guess how many it's going to come out 10:43 with a magnet? 10:44 Sure. Let's do that. How many? 10:46 What do you think with a magnet? 10:47 How many you think? 10:49 One, two, three, four, none? 10:52 Okay. Put two hands up. Put two hands. 10:54 Okay, here we go. I say one. 10:55 Countdown. Let's go. 10:56 Three, two, one, I started here, what happened? 10:59 Here we go. 11:00 Whoo! 11:08 See how fast it went. Yeah. 11:10 Wow! It's an accelerator. 11:11 Well, that magnetic sphere, isn't that interesting? 11:14 An accelerator. 11:15 That is very interesting. 11:17 Okay. So here we have our magnet. 11:20 Okay. 11:21 Our very, very strong magnet is right there, 11:23 isn't that interesting? 11:25 When this ball was coming down, 11:26 it was pulling this ball towards it. 11:29 And as soon as it hit it, whoa, it speeded everything up. 11:32 Let's try it one more time. Are you ready? 11:34 Count down. Three, two. one. 11:37 Look how fast that thing went. 11:39 It went a lot faster, didn't it? 11:41 It did. It really did. 11:43 Now, that's interesting to me. 11:44 Magnets are very powerful, aren't they? 11:46 I love playing... 11:48 But we couldn't even see. 11:49 We couldn't see the magnetic field. 11:51 We can't see them. It's invisible. 11:53 Can you think of anything else that's invisible? 11:57 Can you think of anything else that's invisible? 11:58 Wind. 12:00 I'm sorry. Wind. 12:01 The wind. Yeah, the wind. 12:02 Oh, it's interesting. 12:04 We don't know where it comes from 12:05 or where it goes. 12:07 Okay. That's interesting. 12:08 Wow. What else is invisible? 12:10 You know, that most things are invisible. 12:12 Did you know that? 12:13 Most things are made 12:14 out of things that are invisible. 12:16 You know, the Bible says that God created, 12:17 Jesus created everything 12:19 that we can see, touch, feel and hear. 12:20 He even created things that are invisible 12:23 and you and I and the table and our food and everything 12:27 is made out of things that are invisible. 12:30 It's mostly things are invisible, 12:32 isn't that amazing? 12:33 It's hard to believe. 12:35 It really is. Wow! 12:36 That is exciting 12:37 and I like how the magnetic field, 12:39 because that even puts a protection, 12:41 a hedge around the earth 12:43 and these North and the South Poles. 12:45 That is amazing how God created it, 12:48 and even to go around in the solar system. 12:50 That is just amazing. 12:52 And it reminds me of a Bible text. 12:54 Do you want to pull out a Bible text, Aiden, for us? 12:58 I believe it's found in 1 John 2:6. 13:05 "He who says he abides in Him 13:08 ought himself also to walk just as He walked." 13:12 Who do we wanna walk like? 13:14 Jesus. 13:16 We do wanna walk like Jesus. 13:17 We wanna follow His example. 13:19 Just like these magnets. 13:21 How they connect to each other. 13:23 We wanna be connected to who? 13:25 Who do we want be to be connected to? 13:27 You're right, Jesus and God. 13:29 You're right, we want to be connected totally to Him. 13:31 I'm so glad that God made all these wonderful things 13:35 like these magnets, 13:36 because we can play with them. 13:38 And I see, 13:39 are you already playing with them, William? 13:40 Yeah. 13:42 We enjoy playing with them 13:43 and let's go ahead 13:44 and continue playing because what? 13:46 What do we like to do? 13:48 Oh, this one, 13:49 sometimes we can play connection. 13:50 You have a strong one. 13:52 We've got, maybe let's see. 13:54 I like playing with them. 13:55 I wanted to see if this could roll. 13:57 Whoa! 13:59 I'm trying to see if mine will roll. Nope. 14:01 Sometimes they work, but I like stringing magnets. 14:04 How about you? 14:06 We can see God's creation all around us 14:08 'cause creation is what? 14:09 Science! |
