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, welcome to Creation is Science. 00:36 I'm Aunt Francine and this is Professor Roy. 00:39 I'm delighted to see you. Thank you. 00:41 I think we need to introduce part of our staff. 00:44 Here is Sebastian, Amy, Jefet, and Adrian. 00:48 Are you glad to be here? Yes. 00:50 I see something here. What do you have for us today? 00:53 Well, we've got some liquid nitrogen 00:54 in this ice chest. 00:55 Isn't that cool? 00:57 And we got a little frost over here, 00:58 but you know what we're gonna do is, 00:59 we're gonna take some energy away 01:01 from something. 01:02 When we go outside, 01:04 we're gonna put energy into something. 01:05 That'd be cool. I can't wait. 01:06 So what I have is, 01:08 I have a little racquetball right here 01:09 and the racquetball can bounce. 01:11 So I can bounce it on that steel plate. 01:13 And that bounces pretty well. 01:14 And now, and you can hold that for me. 01:16 But now inside of that 01:17 liquid nitrogen cooler right here, 01:19 I have another racquetball just like that. 01:20 And what we've done 01:22 is we're taking energy away from it 01:23 and we're getting it very, very cold. 01:25 In fact, we're getting that as cold as outer space. 01:27 Do you think it'll bounce if we bounce it? 01:30 No. Oh, let's give it a try. 01:31 Are you ready? Okay. 01:33 You got your safety glasses on? 01:34 Get your safety glasses on, all right. 01:36 Everybody has a safety glass. Okay. 01:37 So what I'm gonna do, I'm gonna put that right there. 01:38 We're gonna give a countdown three, two, one. 01:41 I'm gonna take it out 01:43 and I'm gonna bounce it on here. 01:44 I hope it doesn't hit the ceiling. 01:45 Are you ready? Yes. 01:47 Countdown, let's go. 01:48 Three, two, one and... 01:52 Oh, my... What happened to it? 01:54 Did you find some pieces over there? 01:56 I found some pieces. 01:58 What happened to this racquetball? 02:00 We took so much energy away from it 02:02 and it just cracked into many, many pieces. 02:04 Isn't that cool? 02:06 That is cool. Wow. 02:07 Hey, so what we can do now 02:08 is we can put some energy into a lot of air. 02:11 Would you like to see that? 02:12 Yes, I can't wait. You wanna lead us out? 02:14 Oh, let's go. Let's go. 02:16 Yay! 02:18 Let's find out what's happening. 02:21 Whoa! Did you see this? 02:23 What is it doing? 02:25 What do you think it is? 02:27 I don't know. 02:28 That's pretty cool. 02:29 Is it hot or cold? 02:31 What is it? Cold. 02:32 Cold, but hot looks at the same way, doesn't it? 02:34 Yeah. How did you know if it's cold? 02:36 We got some white stuff around. 02:38 What is that white stuff? 02:39 What do you think that white stuff is? 02:40 Frost. It's frost. 02:42 That's right. Cool. 02:43 Where did the frost come from? 02:44 It's not snowing or nothing. 02:46 Huh? The stuff inside? 02:47 It's warming up. 02:48 How about the moisture in the air? 02:50 Yeah, the moisture in the air. 02:51 We're condensing the moisture in the air 02:53 and it forms that little fog, 02:54 a little, little, crusty stuff over there, 02:55 that frost. 02:57 That's interesting, isn't it? 02:58 Now what do you think we have in there? 03:01 It's liquid nitrogen? That's right. 03:02 We have liquid nitrogen in there. 03:04 Now, liquid nitrogen happens to be the second coldest liquid 03:06 that we know of in the universe, 03:08 isn't that interesting? 03:09 Do you know what the first, first one is? 03:12 No. It's North Dakota. 03:14 No, not really. 03:15 It happens to be liquid helium, 03:16 but we don't have liquid helium. 03:18 We have liquid nitrogen today. 03:19 So we're gonna do an experiment, right? 03:21 Now, take a deep breath. Here we go. 03:23 And exhale. 03:25 Now, most of the air that 03:26 we're breathing right now is made out of what element? 03:29 Say nitrogen. Nitrogen. 03:30 Nitrogen, it's right. 03:32 It's nitrogen about 78% of the air 03:33 that we breathe is nitrogen only about 21% of the air 03:35 that we breathe is oxygen. 03:37 Then we add those two up and we get what? 03:38 78 plus 21 is get that compute 99. 03:42 That's right. 03:44 So 99% of the air is a combination of all that, 03:46 that 1% that's leftover, 03:47 it's another gas that we call argon, 03:49 interesting, isn't it? 03:51 Well, what we're gonna do is if we take liquid nitrogen 03:53 and we change it from a liquid into an air gas 03:56 and it takes a whole lot more space 03:58 and that's what it's all about. 04:00 And we're gonna build up a whole lot of pressure. 04:02 So what I have right here, 04:04 let me go ahead and let me put my glove on. 04:05 We're gonna show you what happens 04:07 with the expansion rate from a liquid, into an air gas. 04:10 So what I have, let me move this over right here. 04:13 I have these little containers right here. 04:14 Do you know what these are? No. 04:15 No, but you know. Film canisters. 04:17 The film canisters. That's right. 04:18 You know our cameras today, 04:20 a lot of our cameras don't use film, right? 04:23 While some do, some professionals may, 04:25 but we use, you know, video, right? 04:26 Sure. 04:27 But what I'm gonna do is I'm gonna pour 04:29 some of this in each one of these 04:30 little cups right here. 04:31 Okay. 04:33 And let's see what we got 04:34 and it's gonna start to boil away. 04:36 By the way the liquid nitrogen is boiling away right now. 04:37 It's boiling right now. 04:39 And the temperature of it 04:40 is about a minus 321 degrees Fahrenheit. 04:44 Do we use Fahrenheit measurements 04:46 in science now? 04:47 Say no. No. 04:49 So we use what? We use what. 04:51 What's the other scale? 04:52 Celsius. Celsius. 04:54 That's right. 04:55 So on the Celsius scale, 04:56 it's about a minus 196 degrees Celsius. 05:00 It's very, very cold. 05:02 Now what I'm gonna do is I'm gonna put 05:03 these little lids on really, really lightly. 05:04 Okay. 05:06 And then here, let me move this over there, 05:07 but be careful. 05:08 All right. 05:10 And I'm gonna put them on really, really tight. 05:11 They snap on really, really tight. 05:12 Then when we do that, 05:14 we're gonna cause a lot of pressure to build up. 05:16 We've got so much pressure to build up. 05:17 What do you think is gonna happen to the lids? 05:19 They're gonna pop off. They're gonna pop off. 05:21 Okay, cool. And maybe you can catch one. 05:22 Okay. I'm not sure. 05:24 Let me put this down here so that won't spill, 05:27 and I'm gonna click them down tight. 05:29 Are you ready? Okay, here we go. 05:31 Oops. 05:32 So there's one, there's two, there's three and there's four. 05:36 And then we'll have a little, oh, there goes one, 05:38 there goes one, there goes one. 05:40 What do we got? You got your glasses on. 05:41 Let's turn to three, we got one more. 05:43 Well, we got one. Anybody catch up? 05:46 I didn't know where that one went though. 05:48 Hey, let's go ahead. Hey would that be... 05:50 Was that fun to see? Yeah. 05:51 Let's supersize this. Okay? 05:54 Let's supersize this. 05:55 We got an experiment 05:56 where we're gonna take all about a hundred milliliters 05:59 of the liquid nitrogen. 06:01 And what we're gonna try to do 06:02 is we're gonna make a canon out of it. 06:04 Would that be cool? Yeah. 06:05 Come on over here. Let's see what we got. 06:06 Come on over here. Let's see what we've got. 06:10 All right. Here we go. 06:11 And here's our little canon, all right? 06:14 There's our canon. 06:15 And let's see, what we're gonna need 06:16 is we're gonna need a little bottle. 06:18 We're not gonna use a film container. 06:20 We're gonna use a bottle. Okay? 06:22 And we're going to put 06:24 a little bit of liquid nitrogen, okay? 06:26 Right inside of our little bottle 06:27 right here. 06:29 Okay? 06:30 And let's see and let's make sure 06:31 we have enough in there. 06:33 Are you ready? I'm ready. 06:34 Okay. If it gets too cold, just yell. 06:36 Okay? All right. There we go. 06:37 And we're making a cloud 06:38 because we're condensing the water molecules in the air. 06:42 We're building up a lot of pressure right there, 06:44 right there. 06:45 Okay. You missed it. 06:46 I'm sorry. That's okay. 06:48 All right. All right. 06:49 There we go. There we go. Thank you. 06:50 And we're going to get some more in there. 06:52 Some more in there. 06:53 Some more in there, some more in there. 06:55 Okay. I think we're good right there. 06:56 This is really cool. Look at that. 06:58 Now it's starting to frost on the outside, isn't it? 07:01 We're picking up some frost right there. 07:02 Okay. 07:04 The next thing we're gonna do is we're gonna come over here. 07:06 All right. And here's our little cannon. 07:08 If you'll take that football... Okay. 07:10 Football out of there. Okay. Okay. 07:11 And we're gonna try to make a field goal with football. 07:14 Whoa! 07:15 We want this to happen really, really quickly. 07:17 So we're going to warm up the liquid nitrogen in a hurry. 07:20 And we can do that if we put it in some water. 07:22 All right? All right. 07:23 So I'm gonna put a little bit of water 07:25 in our little canon right here. 07:27 See what we got right here. See how much water we got. 07:29 Oh, that's just about perfect. All right. 07:31 I'm gonna put the lid back on this right here. 07:33 And maybe you could set that down over there someplace. 07:36 All right. 07:37 The next thing we're gonna do is I'm going to take my lid, 07:40 whatever it happened to my lid, did I do it with my lid? 07:44 You have my lid? No. 07:45 Oh, I need a lid. Maybe this lid. 07:48 I'm sorry. No, you're fine. 07:50 Okay, cool. 07:51 And I'm gonna go is, I'm going put the lid on this 07:54 and I'm gonna drop it in there. 07:56 Okay? 07:57 And then you can hand me the football. 07:58 Okay. 08:00 And then I'm gonna join you over there. 08:01 Do you want this other glove? No, no. 08:02 Okay. All right. 08:04 Here we go. All right. 08:05 So I'm gonna put the lid on this right here. 08:07 All right. 08:08 And get ready to hand me the football. 08:09 Right, get ready to hand me the football. 08:11 Yeah, probably. Okay, here we go. 08:13 We're gonna put it right in there. 08:14 All right, here we go. 08:16 And you might wanna cover your ears 08:17 because that does make a loud noise. 08:18 It should shoot over there someplace. 08:20 How about a countdown? 08:21 Ten, nine, eight, seven, six, 08:25 five, four, three, two, one. 08:29 It should blast. Oh! 08:32 There goes the football, way over there in that grass. 08:36 How about that? 08:38 Isn't that cool? 08:39 That was cool. He's let's come one over here. 08:40 Let's come back over here. Come back over here. 08:44 Let's come back to the table. 08:46 Let's check this out. Let's check this out. 08:49 And pick up a lid if you can find the lid, 08:51 the lids are all over the place. 08:52 Isn't that interesting? That is interesting. 08:55 Look at the bottle. What happened to the bottle? 08:57 Ah, shredded up. 08:59 It just blew apart, isn't that? 09:00 When we get uptight, you know, we could explode, you know, 09:03 people could explode when we get uptight. 09:05 So, you know, but God never gave us a cap. 09:08 Did He? We don't have a screw cap. 09:09 So what do we need to do 09:11 if we get too much pressure inside of us? 09:14 Can we let it out? Yeah. 09:16 What's a good way of letting out pressure? 09:18 Well, I can think of something. 09:19 Sometimes when I get frustrated, 09:21 I need to go outside in nature. 09:23 Do you like to going out in nature? 09:25 Yes. I love nature. 09:27 And sometimes the best place is in a quiet place, 09:30 maybe by the water. 09:32 Do you have a stream by your house anywhere? 09:34 Yeah. I love doing that. 09:36 What do you like to do when there's a lot of pressure 09:39 and you feel stressed out? 09:40 Some people like to do what? 09:41 Kinda disconnect of the world and just go outside and relax. 09:44 Outside and relax. 09:46 What do you like to do? 09:47 I also like nature, 09:48 but sometimes talking to my friends 09:50 or my best friend, God really helps. 09:51 Yeah. 09:53 I thought you might say singing. 09:54 I thought you'd do a lot of singing. 09:56 Yeah, music is nice too. 09:57 Yeah, I thought so. 09:58 How about you, Professor Roy? 10:00 Oh, man, I like to go outside too 10:02 and take walks in nature. 10:03 That's pretty cool. 10:05 These science experiments, that's really a good way. 10:06 It is fun. I love that. 10:08 I love to see that ball, 10:09 it went high up in the air, didn't it? 10:11 It really flew up high. Awesome. 10:13 Very high. 10:15 How about you, Adrian? 10:16 What do you like to do 10:18 when you're feeling a lot of stress and pressure? 10:21 Just go and stay somewhere by myself. 10:24 Sometimes a quiet time. 10:26 How about you, Sebastian? 10:27 Just go outside and sit with by myself. 10:30 I agree. I agree. 10:32 Nature is a really good time to have and outside 10:37 and being out in the sun. 10:39 Sunshine. Yeah. 10:40 And you know, 10:42 it reminds me of a lot of things. 10:43 How far did that go? 10:44 Did that go really far? 10:46 Quite a ways. 10:47 It went really, now is this something 10:49 you can do at home? 10:50 No. Please don't do this at home. 10:52 I've never bought liquid nitrogen, 10:54 because that can be... 10:56 Do it in somebody else's house. 10:57 Yeah, like you said, with the Mentos, right? 11:00 You can do that with the Mentos, 11:02 but you know what? 11:03 I like how far that went, 11:05 and it reminds me of a story in the Bible about mounting on, 11:09 do you know what on? 11:10 Eagle's wings. Eagle's wings. 11:12 I love that song and mounting on eagle's wings 11:15 because God helps us soar further than we can do. 11:18 Does God know your plans? Yes. 11:20 And what He's doing in your life? 11:21 He does. He sure does. 11:22 He has a lot of plans. 11:24 And I really wanna say, 11:25 thank you for all that you're doing 11:26 out here, because this is fun. 11:28 Do any of you have any questions? 11:31 I can think of some. 11:33 Is liquid nitrogen flammable? 11:35 No, you know, it's not flammable at all. 11:36 You put a match in there and it just will go out, 11:39 which is interesting. It's an inert element. 11:42 Things usually don't combine with it. 11:43 Pretty cool. 11:44 It's crystal clear, it looks just like water. 11:46 Didn't it look like water when it went in the air? 11:47 Yes. Yeah. 11:49 It's crystal clear, has no smell, has no taste, 11:51 but do you wanna put it in your mouth? 11:52 No. 11:54 Think I wanna put it in my mouth. 11:55 They do surgery with it too. Wow. 11:56 Let's go. 11:58 Well, have you ever had a wart or something on your skin? 11:59 Yes. 12:01 They can actually freeze it off. 12:02 It's interesting because when this comes in contact 12:04 with your skin cells, 12:05 all of our skin cells has moisture in it, right? 12:08 What happens with water when we freeze it? 12:10 What happens to it? It expands. 12:12 It expands, that's right. 12:14 The crystal end structure gets larger 12:16 and that's what happens to the water in your cells. 12:19 It expands and it ruptures yourself. 12:21 It just ruptures it. 12:23 And that's what kills your cells. 12:24 How interesting? 12:25 They do brain surgery with it too. 12:27 How about that? 12:28 Yeah, it's just awesome stuff, isn't it? 12:29 But it's very, very cold. 12:31 You know, we could make a little 12:34 waterfall cloud coming over there. 12:36 Would that be fun? Okay. Yes. 12:37 I'm just gonna pour it out there 12:39 and watch and see what happens. 12:40 And it makes that cloud 12:41 because of the condensation 12:43 of the water molecules in the air. 12:45 We can't see those little molecules. 12:46 We're gonna see a bunch of them. 12:47 Are you ready? Yes. 12:49 How about a countdown three, two, one. 12:50 Three, two, one. 12:52 Whoa! 12:53 Oh, that's so cool. 12:56 Look at that. 12:57 Oh, there's a little tiny water molecule. 12:59 Wow. Trillions of them. 13:01 That's amazing. It is. 13:02 And it's gonna go away 13:03 just like the clouds that you see sometimes... 13:05 It is. 13:06 They appear and then they, then they just disappear. 13:08 That's fun. Huh? 13:09 Are you ready? It's getting hot out here. 13:10 Oh, I'm ready. Are you ready to go in? 13:12 Thank you. Let's get out of here. 13:13 Let's go. 13:19 I surely enjoyed all that energy. 13:21 Wasn't that powerful? 13:22 Yes. I enjoyed that. 13:24 That reminds me about some strength. 13:27 Can you read that Bible text for us? 13:29 Sure. Amy? 13:31 Can you help us out? 13:33 Was that verse in Isaiah, I believe. 13:35 Isaiah 40:31, and it says, 13:39 "But those who wait on the Lord shall renew their strength, 13:42 they shall mount up with wings like eagles. 13:44 They shall run and not be weary, 13:46 they shall walk and not faint." 13:48 I would like not to ever get tired. 13:50 Wouldn't you like to do that? 13:52 Always have the strength on whom? 13:53 God. From God. 13:55 We can always ask Jesus for a lot of strength 13:58 because He's going carry us through everything. 14:00 Aren't you excited about that? Yes. 14:02 We can see God's creation all around us 14:04 because creation is? 14:06 Science. Science. |
