00:01 The experiments you will see
00:02 have been carefully done by professionals, 00:04 and should not be tried at home without parental guidance. 00:06 Please follow the caution signs throughout this program. 00:33 Hey, kids, are you ready 00:34 for some fun and exciting experiments? 00:36 Today, we're going to learn about Jesus, 00:38 our light and the giver of life. 00:41 And I have here Professor Roy, and I have Leah, Aiden, 00:46 Sebastian, and Jasmine joining us today. 00:49 So I think we're learning a little bit about air, 00:53 is that correct? 00:55 That's right, some air. 00:56 Are you using air? 00:57 Yes. Not hot air, right? 00:59 No, not hot air. Okay. 01:00 But air, air is all around us, isn't it? 01:03 You know, we have heavy air and light air. 01:04 Isn't that right? 01:05 Can you think of something that's light air, 01:07 that's light? 01:08 Helium? Helium. Okay. 01:10 What do you think I have in that balloon? 01:11 Helium. 01:12 We have a helium balloon right here. 01:14 But are there other gases 01:15 that will float a balloon like helium? 01:18 Are there? 01:20 Can you think of one? 01:21 We know the number one lightest gas 01:22 is what? 01:24 It's a gas that starts with H and it's hydrogen, 01:26 that's exactly right. 01:27 And hydrogen, as far as we know 01:29 that Jesus created more hydrogen 01:31 than any other element 01:32 as far as we know in the entire universe. 01:34 That's cool, isn't it? 01:36 Well, today, we've got a neat experiment outside. 01:38 And we're actually going to take 01:39 some air that's outside air, 01:42 and we're going to make some lighter than air 01:45 inside of a big container. 01:47 And you're going to help us do that. 01:49 I can't wait. 01:50 Are you ready to see what happens? 01:52 Yes. 01:53 Oh, let's get ready to head out there. 01:56 And again, you want to follow directions. 01:59 So let's head on out. 02:00 Let's walk on off. Let's go. 02:05 Hey, have you ever wanted to fly? 02:06 Yes. 02:08 You know, I used to have dreams about flying. 02:09 I mean, every night. 02:10 It was crazy. 02:12 But I really wanted to fly, but I can't fly. 02:13 Can you fly? No. 02:15 No. Have you flown before? 02:16 Yes. How did you do that? 02:18 In an airplane. In an airplane. 02:19 Have you flown before? Yes. 02:20 How did you fly? In an airplane. 02:22 In an airplane, hmm. 02:23 What about you? 02:25 It's only the airplane too. The airplane, what about you? 02:27 I wish I could go. An airplane and an airplane. 02:30 Well, you know, we need an airplane to fly 02:32 or a helicopter, right? 02:33 Or maybe a hot air balloon, 02:35 you can kind of fly in a hot air balloon. 02:36 But today we're going to fly in something different, okay. 02:39 This is called a UFO. 02:41 What's a UFO? 02:42 An Unidentified Flying Object. 02:44 An Unidentified Flying Object. 02:47 Interesting, isn't it? 02:48 Now, and it happens to be very, very long, 02:50 it's about 60 feet long. 02:52 And that's why you're part of our ground crew. 02:55 Because your job is to keep it from crashing into the ground. 02:59 And we have to fill it up with air. 03:00 If we're going to fly, 03:02 we're going to need air, aren't we? 03:03 Especially if something's going to be 03:04 floating in the air. 03:06 All right, so here's, here's what we got. 03:07 We got this bag right here. 03:09 In fact, this bag is 60 feet long. 03:11 And it's made out of some material, 03:12 you can touch the material 03:14 made out of very, very thin material. 03:16 And if we're not, if we're not careful, 03:17 you can actually put your finger through the bag. 03:20 We don't want our fingers through the bag, 03:22 because that will start to leak, right? 03:24 We're going to fill it up with some air 03:26 and the air that we're going to use 03:28 is, well, see that leaf blower over there. 03:31 We're going to fill it up using the leaf blower 03:34 and then we're going to seal off 03:35 both ends of this big tube 03:37 because it's about this big around 03:39 about two feet in diameter. 03:41 And then we're going to seal both ends up. 03:43 And then we're going to let something happen. 03:46 We're going to let something do what to the air inside. 03:50 What do you think? 03:52 Let go. 03:53 Yeah, well, no, we can't let it go 03:55 because it'll just keep flying away 03:56 and it'll just be. 03:57 You know, we've had them to go 03:59 a couple of thousand feet in the air. 04:00 That's not a good thing. You don't want to do that. 04:01 So we have to keep them on a string. 04:03 What's going to cause this to heat up? 04:05 Well, how are we going to heat up 04:07 the air inside of this thing? 04:08 We have to heat up the air? 04:10 How could we heat it up in here? 04:12 Think about the color. 04:13 I'm thinking the color I can use up there. 04:15 What can we use to heat up air inside of this? 04:16 Heat. 04:18 Heat, yes, or what's our source of heat? 04:20 The sun. 04:22 The sun, that's right. 04:23 We're going to use solar energy 04:24 in order to heat up the air in here. 04:26 That will be cool, won't it? I think so. 04:28 All right, so here's what we got. 04:29 All right, so in fact, I think we have 04:31 some more helpers for our crew. 04:33 And we're going to get this all lined up over here. 04:37 All right, let's see what we got right here. 04:38 All right. So come over here. 04:41 All right, let's go over. 04:42 And then remember, we need to spread out. 04:44 Here we go, here. 04:45 I want you to take that right there 04:47 and I want you to walk that direction right there. 04:49 We're going to walk right over there by the camera. 04:51 We're going to walk that way. 04:53 Okay, okay, and we need, okay, keep going, keep going, 04:56 keep going, keep going. 04:57 All right. 04:59 Then we're going to have to get space out a little bit 05:00 because we want people to keep this off of the ground, 05:03 you're going to have to keep going, 05:05 you're going to have to keep moving, 05:06 you're going to have to keep going, okay. 05:09 Just keep the string like that. 05:10 Don't let any more string out. 05:12 But I want you to walk. I want you to walk that way. 05:14 I want you to walk that way. 05:15 Now help me to keep this off of the ground. 05:17 Okay, keep going. 05:19 Keep going. Keep going. Keep going. 05:21 Keep going, and we're gonna spread out. 05:23 We're gonna spread out because we don't want it to hit 05:26 the ground, okay? 05:28 Spread out, spread out, spread out. 05:30 Keep going, keep going, keep going. 05:34 This way, right away you need to move this way. 05:36 Here we go. 05:38 Here we go, here we go. 05:39 Amanda, come out of the loop. 05:40 Come down the pipe this way. 05:42 Okay. All right. 05:43 Don't pull on it, don't pull on it. 05:44 You got it? Okay. 05:46 All right. All right, here we go. 05:47 All right, cool. All right. 05:48 Now, what we have to do now is we're going to fill this up 05:50 with some air, okay? 05:51 So that's what we're going to do. 05:53 So we've got our leaf blower, 05:54 and we're going to fill this up with some air. 05:56 Here, can you help me? 05:58 Can you help me up here? Okay, here we go. 05:59 Can you help me also? 06:01 Can you get on this other side and you hold this? 06:02 What we want to do is want to hold it 06:04 open like this with two hands. 06:05 Can you hold it open with two hands? 06:07 All right, here we go. 06:09 All right, we got our little leaf blower. 06:10 We're going to start to fill this up with some air. 06:13 And we're going to try to make this 06:14 as straight as possible right here. 06:16 Can we get it straight? 06:18 No, no, no, you stay where you're at, 06:19 you stay where you're at, 06:21 and I'm going to direct the air. 06:31 And you gonna have to let me know 06:32 when it's quite full there. 06:36 Okay, I'm getting it. Okay. 06:38 Hold it, hold it close to that. 06:39 Hang on to it. Okay. 06:41 Okay. All right. Okay. 06:43 Close it up, close it up right there. 06:44 There we go. We're gonna close this up. 06:46 Okay, here we go. Try to keep it off the ground. 06:50 Okay, move this way, so we take it off the ground. 06:53 We got a little bit of wind going over here. 06:56 Okay. See, what we've got. 06:59 Oh, we got to attach. How are we doing here? 07:00 Now hold on. 07:02 Oh, do I already have a hole in it? 07:03 A little bit. 07:06 We have a big hole? 07:08 Oh, my. 07:09 Okay, so we got a big hole in it. 07:11 Okay, so... 07:12 Don't hold on to it like that though. 07:14 You got to just hold it up. 07:15 So just you're touching the bottom. 07:18 Okay, how are we doing? 07:21 Are there no holes now? 07:22 Uh, no. Okay, all right. 07:25 So what I'm going to do is I'm going to go ahead, 07:26 I'm going to tie my end off right here. 07:29 Here we go. 07:30 And let's see, we're going to need 07:32 the scissors down here, okay. 07:33 And let's see what we got. 07:34 I'm going to pull this through here. 07:36 We still need you to hold this so it doesn't fly away. 07:38 Hold on to it. 07:40 Okay, all right. There we go. 07:43 If you'll just hold that, hold this for me. 07:44 Okay. 07:45 What I'm going to do is I'm going to go ahead 07:47 and I'm going to tie this because we've got to have, 07:49 we have to tie it so it doesn't fly away. 07:52 That would be bad news if it flew away. 07:53 No, we don't want that to fly away. 07:55 No, we don't. 07:56 Okay, and what it's doing right now 07:58 it's absorbing a lot of heat energy 08:00 from the sun, right? 08:02 And pretty soon if you just cut it right there. 08:05 Cool. There we go. Right. There we go. 08:08 We got it, just like that. 08:09 Let's see what we got. 08:11 Okay, now, if that wants to go up, 08:13 then we're just going to let it go up. 08:14 Why don't you come over here and help? 08:16 No, you, yes, come on over here and help me. 08:17 Okay, there you go. 08:18 You hang on to that for us. All right. 08:20 We're just going to see if it's going to fly? 08:22 No, don't grab it. 08:23 We're going to try to keep it up if we can. 08:27 Okay, we're going to try to keep it up. 08:29 If it's going to go, if it tries to come down, 08:31 you can try to keep it up. 08:33 I definitely try to go that way. 08:36 Oh, wait, somebody let go of the string. 08:38 Okay, grab the string down there, 08:40 but let some more string out. 08:43 Get more string out. All right. 08:45 Now you can. 08:46 Okay, we're trying to heat up that air, 08:48 that solar energy is heating up the air inside 08:52 just keep it off of the ground. 08:54 Don't push it, okay. 08:55 If it wants to fly, let it fly. 08:58 Okay, just keep letting it off. 08:59 There we go. Keep letting it off. 09:01 There we go. 09:03 Okay, it's flying pretty good right now. 09:05 Keep going. Keep letting some off. 09:06 Keep letting it some off. 09:08 Just keep it from, there you go, 09:09 keep it off the ground. 09:11 Okay, yeah, you can let 09:12 some more string out down there, okay. 09:15 Letting it go. Watch out, watch out. 09:17 How are we doing? 09:18 Are we doing good? 09:20 Is it flying? Yeah. 09:22 Okay, it's flying. 09:24 And it should go up a little bit higher right here. 09:27 Okay. So the sunlight is doing what? 09:30 It's heating up the air inside. 09:32 And what happens when we heat air up? 09:34 When we heat air up, what does it do? 09:36 It goes up. 09:37 It starts the molecules of air 09:38 move faster and faster and faster, 09:40 and that the molecules actually take up more space. 09:44 And so the bag is getting larger 09:46 because of that expanding air. 09:48 And then the air around it is heavier 09:51 than the air inside of the bag. 09:53 So it wants to fly. 09:54 Now we do have hot air balloons 09:56 but we have to put hot air in them 09:57 from a furnace or a fire 09:59 but here we're using sunlight, sun energy to heat it up. 10:03 You can go, everybody walk this way. 10:05 Come this way. 10:06 No, not yet. We might break the string. 10:09 Might be too much tension. 10:12 And this will even work in the wintertime, 10:14 isn't that interesting? 10:15 It'll work in the wintertime because in wintertime, 10:17 you have what? 10:18 We still have sunlight. 10:20 And that's what we need. 10:21 Why do you suppose that this big tube, 10:24 this big solar bag is so black in color or dark in color? 10:29 As black absorbs more heat. 10:30 That's right, black absorbs more heat. 10:32 If it was white, you think it would do that? 10:35 No. No, it wouldn't. 10:36 Hey, look at that. 10:38 Man, look, it's almost straight up and down. 10:40 How cool is that? 10:41 That's amazing. That is amazing. 10:44 So color makes 10:46 a lot of difference, doesn't it? 10:47 It does. 10:49 That's right, if you had a dark colored car, 10:51 or a white colored car which would be hotter? 10:53 The black. 10:55 The dark one because it would absorb 10:56 that heat energy, that is interesting. 10:59 And it wants to fly away, look at there. 11:01 Yeah, just keep it off the ground. 11:02 There we go. Keep it up, keep it up. 11:04 We got some wind 11:05 and so that complicates things just a little bit. 11:08 But it's flying away from us. That is so cool. 11:11 How cool is that? 11:12 Thank you, Jesus, that is so amazing. 11:16 Aren't you thankful that Jesus provides all the sunlight? 11:20 Yes. 11:21 How many of you are thankful 11:22 that Jesus is providing all the sunlight for us? 11:25 Because in the Bible, 11:26 it talks about Jesus being the light, right? 11:28 Yeah. Yeah. 11:29 Jesus is our light. 11:31 That is awesome. 11:34 I can't wait. Can you think of another... 11:36 Oops, oops, oops, oops. 11:38 How about Jesus being the light? 11:41 How many of you are scared of the darkness? 11:45 Are you scared of the darkness? 11:46 No, because who's our light? 11:48 Jesus. Jesus, yay! 11:51 That is awesome. Thank you, Jesus. 11:54 Let's wrap it up. 11:56 That was so much fun. 11:58 Didn't you enjoy that? Yeah. 11:59 I'm glad to be coming in in the air conditioning. 12:01 That was pretty hot, wasn't it? 12:03 Yeah. 12:04 That was amazing about the different kinds 12:06 of how the air was moving in it. 12:09 You were having a lot of fun holding it up, weren't you? 12:12 Reminds me of Jesus talking about 12:15 the light of the world. 12:17 I think, Sebastian, can you grab that Bible for me? 12:21 And I think it was, and let's see John 8:12, 12:26 I think it was John 8:12. 12:27 Let's, can you read that for us please? 12:30 "Then Jesus spoke to them again, saying, 12:33 'I am the light of the world. 12:34 He who follows Me shall not walk in darkness, 12:37 but have the light of life." 12:39 The light of life. 12:40 That reminds me that, 12:41 yes, Jesus is the light of the world. 12:43 And remember how the bag was dark, right? 12:48 What was happening with the bag that was black? 12:51 It was absorbing sun. 12:53 It was rising. 12:54 Do you think it would have worked it 12:56 as well if it was clear? 12:57 No. Why not? 12:59 Because it wouldn't absorb the sun. 13:00 It wouldn't absorb the sun. 13:02 And who do we want to reflect? 13:03 Jesus. 13:05 We want to reflect Jesus and His light 13:07 because He is the source of light, 13:08 just like the sun was the source of light, right? 13:12 Yes. I think so. 13:13 He was the source of light. 13:15 And yet, all of that we want to be 13:17 like Jesus and have that source of light. 13:19 And I am so thankful because without the sun, 13:22 would anything grow? 13:23 No. 13:24 Would we be able to live on this earth? 13:26 No. 13:27 No, we need the sun, the sunlight. 13:29 But most of all, who do we need for our breath? 13:32 God. Jesus. 13:34 Jesus is our Savior. 13:35 And don't we want to ask Him all the time daily 13:38 to have Him in our hearts all the time? 13:40 Don't you agree? 13:41 Is there anything else that you wanted to say? 13:43 Absolutely. 13:44 Well, you know, Jesus created 13:46 all that just for us, didn't He? 13:47 He did. 13:48 All that air, that atmosphere... 13:50 Me being able to take a big breath. 13:51 Can you take a big breath for every... 13:54 Yeah. 13:55 Can we blow that balloon, let's try. 13:57 One, two, three. 13:59 Woah! Woah! 14:00 It might take away 14:02 and I am so thankful 14:03 that Jesus is always the light. 14:05 We can see God's creation all around us 14:08 because creation is... 14:11 Science. |
